42b66bd809 QTaggedPointer: disable operator= with an empty initializer list
Given a QTaggedPointer, users may write

  taggedPtr = {};

to mean "reset it". This is error-prone: due to overload resolution,
this actually ends up calling QTaggedPointer<T>::operator=(T *),
which changes the pointer but *not* the tag, and not the implicitly
declared QTaggedPointer<T>:operator=(const QTaggedPointer<T> &)
which would reset both pointer and tag.

Given the idiomatic usage of {} is indeed to perform a full reset (cf.
std::exchange(obj, {}), std::take, etc.), work around this by disabling
the operator= overload for pointers in case an initializer list is
passed. In other words, make `={}` fall back to the implicitly
declared overload.

Note, this breaks some usages, such as

  taggedPtr = {rawPtr};

but at least we get a compile error for these, and they don't look
common at all.

[ChangeLog][QtCore][QTaggedPointer] The operator assignment
taking a raw pointer has been reimplemented in order to avoid
subtle issues when assigning `{}` to a QTaggedPointer. This will
cause code that assigns a braced-init-list to a QTaggedPointer object
to stop compiling (for instance, `tagPtr = {ptr}` is now ill-formed).

[ChangeLog][QtCore][QDateTime] The 't' format character in a

0bc92c01e3 Support parsing time-zone specifiers more selectively
[ChangeLog][QtCore][QDateTime] The 't' format used in fromString() can
now be repeated to restrict parsing to particular forms. Thus 'tt' now
matches the [+-]hhmm offset format (no colon), 'ttt' the [+-]hh:mm

how to interpret as a zone specifier.

1e625033be tst_QSharedMemory: remove mention of gravlaks.troll.no
It was our old, HP-UX machine on Itanium (ran on big-endian mode). We
don't support HP-UX any more; HP will still support the 11i v3 release
until 2025, but I doubt anyone wants to run any new software there. One
hopes that HP has long since fixed the issue, but I doubt it since the
last release is from 2007. Gravlaks probably ran HP-UX 11i v3.

There are a couple other left-overs of ".troll.no" in the repository,
the majority of which are URL manipulation in tst_qurl.cpp and in
tst_qnetworkcookie.cpp, then the certificates for fluke.troll.no (valid
until 2035) and aspiriniks.troll.no (expired in 2009, but we don't need
it for validity).

7a7051b58f QMetaType: Support custom unary converters with optional<To> return type
To indicate success of a conversion, the public API has previously only
supported registering member functions of the form To (From::*)(bool *).
When adding custom converters for types that cannot be modified, this is
usually not a possibility.
As an alternative, this patch adds support for std::optional in the
UnaryFunction overload of QMetaType::registerConverter. If the returned
optional has no value, the conversion is considered failed.

d8387fc538 Reduce foldCasing of the needle in Boyer-Moore QString searches
Before searching, foldCase the first up to 256 characters, and use this
buffer to compare against the haystack. If the needle is larger than the
buffer, compare the rest of the needle against the rest of the haystack
for every potential match. The buffer is placed on the stack and must be
refolded for each search, but this change does not break the API.

This is faster than the old implementation, except if the needle is long
and it is found near the beginning of the haystack, or if the needle is
long and it is not found in a short haystack where few comparisons are
done and hence few case foldings were needed in the old implementation.

Benchmarking using tst_bench_qstringtokenizer tokenize_qstring_qstring
shows an improvement for the the total testcase and usually for each
individual test.

24dedaeaa1 QFuture: fix handling of cancelled continuation chain
To support cancellation of continuations attached via the parent future,
for each future returned by a continuation we store a pointer to its
parent (i.e. future the continuation is attached to). Later, before
executing a continuation, we go through chain of parents and check if
any of them is cancelled. However, if one of the parents is destroyed
while the chain is executing, the next continuations' parent pointers
will become invalid. So storing the parent pointers isn't safe.

This commit changes the logic of handling the cancelled continuation
chain in the following way:

- Instead of storing a parent pointer in the continuation future's data,
  we do the opposite: we store a pointer to continuation's future in the
  parent.
- When a future is cancelled, we mark all continuation futures in the
  chain with a flag indicating that the chain is cancelled.
- To guarantee that the pointers to continuation future's data don't
  become invalid, we clean the continuation (that stores a copy of its
  future's data and keeps it alive) only when the associated promise
  is destructed, instead of cleaning it after the continuation is run.

The long term goal is to port QSettings registry code to

much more registry code in QSettings and migrate them to this
class needs a large refactor, so jsut leave it for now. Will
fix it in some future commit.

6a14ad4993 Perform uiLanguages() likely-adjusted processing purely on IDs
The collection of translations available to us need not have anything
to do with whether CLDR has matching data, so preserve the system UI
language list's entries as they are, rather than forcing them through
the QLocale constructor's exercise of likely sub-tag rules.

Instead, simply parse the given locale tags to QLocaleId instances and
use these in the likely-subtag processing to determine what other
entries to add to the list in addition to those supplied by the
operating system. Since going via QLocale did usually supply a
territory, that was included in the BCP 47 name, it's now possible for
the given entry to lack the language_territory name, so be sure to add
that if missing.

This incidentally reduces heap traffic and saves a fair deal of hidden
likely-subtag processing in calls to the constructor and bcp47Name().

Expand testing of QLocale::uiLanguages(), both plain and system.  In
the process, cross-link the two closely-related tests, move a comment
on one's _data() to the other's, where it really belongs, and add
reporting of the actual lists on failure. Enable MySystemLocale to
remember the requested locale's ID, before likely sub-tag processing,
so that we can make query() report results for language, script and
territory as requested, to ensure the fake system locale really does
match what was requested. The new german-britain test failed without
it, because there is no de-GB locale in CLDR.

753bfdf6a1 Work round macOS's omission of en_DE from its own uiLanguages()
When the system locale is en_DE, macOS seems to think we should use
en_GB as the right translation. While that probably is a sensible
choice in the absence of an en_DE translation, we should definitely
use the en_DE translation if available, especially if en_GB isn't
available (which lead to a fall-back to de_DE, given later entries in
macOS's list). So prepend the system locale's own pcp47Name() if it
(isn't the C locale and) is missing from what we would otherwise have
used for uiLanguages(), after likely sub-tag perturbations.

Add a test simulating (some approximation to) what macOS was doing
that would have caught this case; and add a scope-guard reporter to
the test to report what shows up when lists don't match.

cd4a3a1dc7 CMake: Fix tst_qlibrary to work on macOS with debug builds
The test expects the helper libraries to contain the .dylib suffix
rather than .so.

Replace glob copying of the libraries (which depends on the underlying
shell) with manual copy calls.
This also ensures the libraries don't contain a _debug postfix in the
file name even in a debug build, which would break the tests.

[ChangeLog][QtCore][Meta Objects] The QMetaObject::invokeMethod() taking
a method name by string, QMetaObject::newInstance(), and
QMetaMethod::invoke() now support more than 10 arguments.

[ChangeLog][QtCore][Meta Objects] The use of the Q_ARG and Q_RETURN_ARG
macros is now optional with QMetaObject::invokeMethod(),
QMetaObject::newInstance(), and QMetaMethod::invoke(): the type name
will be obtained from the C++ type (the same as QMetaType). The function
qReturnArg() can be used in place of the Q_RETURN_ARG macro. The macros
are still useful in rare conditions where the type was typedef'ed from
its original name.

95542b386a tst_qobject: port away from deprecated methods
The patch includes the following replacements:
* QMetaType::type("name") -> QMetaType::fromType<Type>().id()
* QMetaProperty::type() -> QMetaProperty::typeId()
* QVariant::Type -> QMetaType::Type
* qRegisterMetaType<T>("name") -> qResigeterMetaType<T>()
* The static QMetaType::{load,save} methods are replaced with

* Replace QCOMPARE(property.type(), QVariant::UserType) with
  QCOMPARE_GT(property.typeId(), QMetaType::User), because the

  (id >= QVariant::UserType) as QVariant::UserType, while the

6234182d82 QMetaType: don't use global relocations to the lambdas and structures
The way the Qt 6.0 QMetaTypeInterface was designed, using a static
inline variable in a template, would normally require the linker and
dynamic linker to merge all copies and choose a single copy as the
official one. But because of hidden visibility and of Windows DLLs,
QMetaType already copes with multiple copies NOT getting merged. So we
may as well ask the linkers not to bother and use simpler, local
relocations to find those symbols.

They are all supposed to still be equivalent and it's an ODR violation
if they're not.

The Apple ld64 linker complains if you use this type of global
relocation:

15422d191f qputenv: defend against non-NUL-terminated QByteArray values
The old code assumed that a QByteArray's data() is always
NUL-terminated. Due to the conflation of owners and non-owners in
QByteArray (but also in case we ever get efficient substringing), this
is not always the case, e.g. QByteArray::fromRawData() does not ensure
NUL-termination.

From QString::utf16(), we learn that the condition to check for is
QArrayData::isMutable(). After working around the fact that
QByteArray::data_ptr() doesn't exist for const QBAs and that empty
QBAs always refer to QByteArray::empty_, which is !isMutable(), we can
detect this situation and re-allocate without introducing new API.

This is the fix for Qt ≤ 6.4. For Qt 6.5, we'll port the function to
QByteArrayView.

0a36a7c1db Make 'zz' format an alias for 'z' in time format strings
Also document the (seldom helpful) handling of over-long repeats of a

[ChangeLog][QtCore][QDateTime] Doubling the 'z' format in a date-time

Previously, this would have produced two copies of the milliseconds
field (eliding any trailing zeros in each). Contrast with 'zzz', which
produces the full milliseconds field, including any trailing zeros.

f1b1773d0a QProperty: Notify observers even when dependency is gone
Problem description:
--------------------
Assume we have two properties, P1 and P2. Assume further that we assign
a binding to P2, so that it depends on P1. Let the binding additionally
capture some (non-QProperty) boolean, and only create the dependency to
P1 if the boolean is true.

The state afterwards is
P1:[p1vaue|firstObserver]
                      |
                      |
                      v
                ---[p2binding]
	       /
P2:[p2value|binding]

If the boolean is set to false, and P1 changes its value, we still
correctly re-evaluate the binding and update P2's value. However, during
binding evaluation we will notice that there is no further dependency
from P2 on P1, and remove its observer.

The state afterwards is
P1:[p1vaue|firstObserver=nullptr]

                ---[p2binding]
	       /
P2:[p2value|binding]

Then, during the notify phase, we traverse the observer's again,
starting from P1's firstObserver. Given that it is nullptr now, we never
reach P2's binding, and thus won't send a notification from it.

Fix:
----

We store a list of all visited binding-observers (in a QVarLengthArray,
to avoid allocations as long as possible). After the binding evaluation
phase, we then use that list to send notifications from every binding
that we visited. As we already have a list of all bindings, we no longer
need to recurse on binding-observes during the notification process;
instead, we only need to deal with static callbacks and ChangeHandlers.

The pre-existing notification logic is still kept for the grouped update
case, where we already have a list of all delayed properties, and should
therefore not encounter the same issue. Unifying its codepath with the
existing logic is left as an exercise for a later patch.

e540d4a864 QRegularExpression: introduce (global)matchView
QRegularExpression::match (and globalMatch) is currently overloaded
for QString and QStringView. This creates a subtle API asymmetry:

  QRegularExpression re;

  auto m1 = re.match(getQString());       // OK
  auto m2 = re.match(getStdU16String());  // Dangling

This goes against our decision that every time that there's a possible
lifetime issue at play, it should be "evident". Solving the lifetime
issue here is possible, but tricky -- since QRegularExpression
is out-of-line, one needs a type-erased container for the input
string (basically, std::any) to keep it alive and so on.

Instead I went for the simpler solution: deprecate match(QStringView)
and introduce matchView(QStringView) (same for globalMatch). This
makes it clear that the call is matching over a view and therefore
users are supposed to keep the source object alive.

Drive-by, remove the documentation that says that the QString
overloads might not keep the string alive: they do and forever will.

[ChangeLog][QtCore][QRegularExpression] Added the matchView()
and globalMatchView() functions that operate on string views.
The match(QStringView) and globalMatch(QStringView) overloads
have been deprecated.

74fac865cf QMetaType: add registerType() and qRegisterMetaType(QMetaType)
This also rewrites QMetaType::id() on top of the helper, with the benefit
of calling a member static function, so QMetaType doesn't need to be
spilled onto the stack. In some upcoming changes I need to ensure that
QMetaTypes are registered so they can be found by name and I'd like to
have a dedicated function name for that, instead of calling .id().

Since I needed to add docs for the new function, I've updated for the
old one too.

[ChangeLog][QMetaType] Added QMetaType::registerType() and an overload
of qRegisterMetaType() taking QMetaType (the two functions do the same
thing). These two functions ensure a given QMetaType is registered with
the Qt global registry, so they can be found by name later. Using
qRegisterMetaType<T>() also accomplishes the same thing, but is slightly
better for completely generic code because it will avoid emitting the
registration for built-in types.

6f852935e0 QString: fix lifetime issues with QRegularExpression APIs
QString has several functions taking a QRegularExpression: indexOf(),
contains(), and so on. Some of those have an out-argument of type
QRegularExpressionMatch, to report the details of the match (if any).
For instance:

  QRegularExpression re(...);
  QRegularExpressionMatch match;

  if (string.contains(re, &match))
    use(match);

The code used to route the implementation of these functions through
QStringView (which has the very same functions). This however opens
up a lifetime problem with temporary strings:

  if (getString().contains(re, &match))
    use(match); // match is dangling

Here `match` is dangling because it is referencing data into the
destroyed temporary -- nothing is keeping the string alive. This is
against the rules we've decided for Qt, and it's also asymmetric with
the corresponding code that uses QRegularExpression directly instead:

  match = re.match(getString());
  if (match.hasMatch())
    use(match); // not dangling

... although we've documented not to do this. (In light of the decision
we've made w.r.t. temporaries, the documentation is wrong anyways.)
Here QRE takes a copy of the string and stores it in the match object,
thus keeping it alive.

Hence, extend the implementation of the QString functions to keep a
(shallow) copy of the string. To keep the code shared as much as
possible with QStringView, in theory one could have a function taking a
std::variant<QString, QStringView> and that uses the currently active
member. However I've found that std::variant here creates some abysmal
codegen, so instead I went for a simpler approach -- pass a QStringView
and an optional pointer to a QString. Use the latter if it's loaded.

QStringView has some inline code that calls into exported functions, so
I can't change the signature of them without breaking BC; I'm instead
adding new unexported functions and a Qt 7 note to unify them.

122270d6be Long live the ICU-based QStringConverter interface!
This adds support for additional codecs to QStringConverter when ICU is
available.

We store the converter in the state (d[0]), and its canonical name in
d[1]. We need the name there, as in the clear function we close the
UConverter, and set the pointer to null. Consequently, the actual
conversion functions might need to re-open the converter again. The
advantage of this approach is that clear is used in the destructor of
State, and with this approach we properly clean up the state.
There is however a disadvantage: The clear function was so far also used
for resetting the state when QStringConverter::resetState . Discarding
the whole Uconverter for that is however rather costly. For that reason
we modify resetState to call a new function, State::reset. For existing
converters, it behaves the same as clear; for the ICU based converter,
we call the more efficient ucnv_reset. Code compiled against Qt 6.4 can
benefit from this more efficient version; code compiled against older Qt
versions will continue to work, as the conversion functions can just
recretate the converter from the name.
We can distinguish between ICU and non-ICU converters by checking if the
UsesIcu flag is set.

QStringConverter::name is changed to return the name stored in d[1]. The
interface of the ICU converter has a dummy name, so code using the old
name function from QT < 6.4 still returns something, namely a message
asking the user to recompile.
The function is moved out of line, as we need to check for the private
ICU feature, and want to avoid having that check in the public header.

As the QStringConverter ctor taking a name now can allocate memory, it
can no longer be noexcept. Removing the noexceptness is safe, as it was
only added after Qt 6.3.

Note that we cannot extend the API consuming or returning Encoding, as
we use Encoding values to index into an array of converter interfaces in
inline API.

Further API to support getting an ICU converter for HTML will be added
in a future commit.

Currently, the code depending on ICU is enabled at compile time if ICU
is found. However, in the future it could be moved into a plugin to
avoid a hard dependency on ICU in Core.

[ChangeLog][Corelib][Text] QStringConverter and API using it now
supports more text codecs if Qt is compiled with ICU support.

0681a2dd5a QTestLib: rework QTest::compare_helper()
[ChangeLog][QTestLib] QCOMPARE now evaluates toString() on its
arguments lazily, speeding up the general case where the comparison
doesn't fail. This is true for the QCOMPARE functionality provided
by Qt. If you specialized qCompare() for your own types, then you
need to change its implementation in line with Qt's own qCompare()
specializations in order to enable this feature.

[ChangeLog][QTestLib] QCOMPARE calls with nullptr argument(s) will
now print the actual and expected values upon failure.

Previously it was not like that because of the compareHelper()
overload in qtestresult.cpp that treated the presence of
nullptr-arguments as a reason to ignore formatFailMessage() call.
New implementation does not have this check, and correctly
executes formatFailMessage() for all arguments.

Note that the qCompare() overloads that call QTestResult::compare()
internally were not affected by this patch, because they already
defer toString() invocation until the comparison fails.

Some numbers, collected against shared release developer build.
I checked how this change affects the test execution. The idea was
to pick some tests for types that do not have a specific
QTestResult::compare overload, so I picked a couple of QByteArray
tests.
The comparison is done by running a test 10 times and taking the
average execution duration, as reported in the log.

tst_qbytearrayapisymmetry:
 Before: 15.6 ms
 After:  14.2 ms

tst_qbytearray:
 Before: 41 ms
 After:  36 ms

The benefit is around 9% and 12% respectively.

5e48a51608 Long live QAtomicScopedValueRollback (private API)!
QScopedValueRollback has a few users that apply it on QAtomicInt,
which happens to work as QAtomicInt is copy-constructible and its
ctors are implicit.

But that's of course nonsense. We don't need to store the oldValue in
an atomic, nor do we need to pass the new value into the ctor as an
atomic.

So, add a QAtomicScopedValueRollback which works on std::atomic as
well as the Qt atomics, but distinguishes between the reference (which
is atomic) and the value (which isn't), and use it in one of the
users, tst_QList.

Keep it private until we know whether there's an actual need for this.

The test is a copy of tst_qscopedvaluefallback, so the occasional
oddity (like atomic op*=) should be ignored.

dd8da7ebd9 Compile-time generate a JNINativeMethod from a C function
Add a template function that allows us to get the method signature
string from a free function, which are used as native callbacks methods
from Java.

Provide a macro that defines a signature object, and a JNINativeMethod
object based on it, in an internal namespace so that we don't pollute
the namespace with generated names.

Add another macro to get the generated JNINativeMethod object based on
the free function name.

Lastly, add overloads to QJniEnvironment::registerNativeMethods that
take a std::initializer_list of JNINativeMethods.

We can now declare a free function to be a JNI native method:

static bool callbackFromJava(JNIEnv *e, jobject /*thiz*/, jstring p1)
{
   // ...
}
Q_JNI_DECLARE_NATIVE_METHOD(callbackFromJava);

and register it with the JNI environment like this:

QJniEnvironment jni;
jni.registerNativeMethods(clazz, {
    Q_JNI_NATIVE_METHOD(callbackFromJava)
});

removing a significant amount of boiler plate code.

367092d7e0 Return specific types for frequently used Java objects
This allows us to specialize JNI type signature templates for e.g. the
context object, which in Java signatures is "android/content/Context".

Introduce a Q_DECLARE_JNI_TYPE macro that takes care of the plumbing.
The types declared this way live in the QtJniTypes namespace, and
transparently convert from and to jobject. Since jobject is a typedef
to _jobject* we cannot create a subclass. Use a "Object" superclass
that we can provide a QJniObject constructor for so that we don't
require the QJniObject declaration to be able to use the macro.

The APIs in the QNativeInterface namespace doesn't provide source or
binary compatibility guarantees, so we can change the return types.

601dbd6499 Add variadic template overloads for QJniObject/Environment methods
This allows the compiler to deduce the template arguments based on the
provided method parameters, which we can then pass to the methodSignature
and fieldSignature helpers to generate the signature string completely at
compile time.

Since we can't partially specialize template member functions, replace
the specializations for void methods with compile-time-if branches in
the general templates.

This variadic template now prevents implicit conversion from the
LiteralStorage types to const char* signatures, so catch the case where
such a type ends up in the parameter list.

Due to overload resolution rules for constructors, we need to explicitly
disable the constructor if any of the arguments is a string literal type,
as we have to keep the old C-style variadic function working for such
calls.

Add variations that use the variadic templates to the unit tests.

[ChangeLog][QtCore][QByteArray/QByteArrayView/QLatin1String/QString/QStringView]
The string-to-integer conversion functions (toInt() etc) now support

make toInt() (etc) skip an optional 0b.

[ChangeLog][QtCore][Important Behavior Changes] Due to the
newly-introduced support for 0b (binary) prefixes in integer parsing,
some strings that were previously rejected as invalid now parse as

0b5b98c4ae Fix qlocale_unix's handling of uiLanguages to take script into account
Some languages have, in the same territory, locales for more than one
script. In such cases, since we ignored the script, we got the one
that is used by default, instead of the one actually asked for. Take
the script into account.

Added TODO comment in test listing the known examples of this;
manually tested before and after the fix to verify the prior code was
indeed getting it wrong and now does do it right.

7a7f2547f3 Return more specific entries before less in QLocale::uiLanguages()
The documentation overtly listed entries in this order but the code
gave less specific entries before more specific (and the tests
verified the same). This is now reversed.

[ChangeLog][QtCore][QLocale] uiLanguages() now prefers more specific
locale names over less specific ones, matching its own documentation,
except where the system backend supplies them in some other order.
This means a translation with the expected script and/or territory as
well as language will be used in preference to a generic one for just
the language, rather than only as a fall-back when the more generic
one is missing.

2b16997116 Clean up tst_QSettings::testVariantTypes()
Give the macro and its parameters clearer names, wrap the macro body
in do {...} while (0), use QCOMPARE() rather than QVERIFY()ing
comparisons, convert the result type to QMetaType::Type rather than
QVariant's deprecated equivalent, save one macro parameter by using
decltype() on another. Simplify one check by pulling out a common
sub-expression as a local variable.

In the process, give the settings keys meaningful names rather than
just "key" with a numeric suffix.

Ideally this test would be reworked to be data-driven, instead of
using macros, but the use of qvariant_cast<> to convert a read-back
value, along with the variable type of the input value compared to the
result of that cast, precludes this (as far as I can see).

7de83f06c1 QDateTime: add conversions for time_point and zoned_time
In C++20, QDateTime is a direct equivalent of a sys_time<milliseconds>
time point. (Before, it might not have been, because system_clock before
C++20 was not guaranteed to be tracking Unix time, AKA UTC time without
leap seconds.) To be specific, sys_time<milliseconds> corresponds to
a QDateTime using the Qt::UTC timespec.

This patch:

1) adds named constructors taking time_points:

* a generic one taking any time_point convertible (via clock_cast) to
  a system_clock (this obviously includes system_clock, but also e.g.
  utc_clock)

* another couple taking local_time, interpreted as a duration from
  1/1/1970 in local time.

2) adds a named constructor from zoned_time (i.e. a sys_time + a
   timezone), that we can easily support via QTimeZone.

3) add conversion functions towards sys_time, matching the existing
   to(M)SecsSinceEpoch() functions.

[ChangeLog][QtCore][QDateTime] QDateTime can now be constructed
from std::chrono::time_point objects (including local_time), as
well as from std::chrono::zoned_time objects. Moreover, they
can be converted to std::chrono::time_point using system_clock
as their clock.

2e29f55f76 QDate: add conversions for std::chrono calendaring classes
std::chrono::year_month_day and related classes offer very
convenient to specify dates.

This patch adds implicit constructors to QDate to support this
convenience, e.g.:

  // YYYY-MM-DD, DD-MM-YYYY, MM-DD-YYYY formats:
  QDate d1 = 1985y / December / 8;
  QDate d2 = 8d / December / 1985;
  QDate d3 = December / 8d / 1985;

  // Indexed weekday:
  QDate d4 = 2000y / January / Monday[0];
  QDate d5 = 2000y / January / Monday[last];

and so on.

These are all implemented using the conversion from the std
calendaring classes to sys_days. Conversions between sys_days
and QDate are also added, since they're basically "for free".

I don't expect "ordinary" users to stumble upon it, but it's
worthy mentioning that std::chrono::year *does* have a year
zero (hence, year_month_day in year 0 or below are offset
by one with the corresponding QDate). I've left a note
in the documentation.

[ChangeLog][QtCore][QDate] QDate (and therefore QDateTime)
is now constructible using the year/month/day/week classes
available in the std::chrono library. Moreover, it now
features conversions from and to std::chrono::sys_days.

33c88f86b5 QAbstractProxyModel: do not access invalid indexes
QAbstractProxyModel::headerData tries to do the "smart" thing and
map sections in the proxy to sections in the source. However there's
no "mapSectionToSource" virtual. Instead, to map horizontal headers, the
code builds a proxy index at row 0 and section N, maps it to the source,
and finds out which source column it gets mapped to. (Same story
for the vertical headers).

... in general this can obviously fail, say you've got a "horizontal
scrambling" proxy model, but in the common case this is OK.

Except, if the proxy is empty (e.g. 0 rows or columns). In this case,
it asks for an illegal index, and if you reimplemented index() yourself
(which you must, since it's a pure virtual in QAPM) and you do bounds
checking, you'll not be pleased at the result.

This turns out to be a massive API liability. To fix this somehow properly,
we can decide that empty models don't get the section remapped (easy).
Less easy is the fact that, when the model does get some data, we have to
emit headerDataChanged() otherwise the views will get broken. So add
this logic too.

Note that QAPM does not normally forward any source model's signal -- a
subclass has to connect to them and handle them explicitly. That's
*another* API liability, all over the place -- data(), headerData(),
flags(), etc.

What I mean by this is that one can create a valid QAPM (by implementing
its pure virtuals) that however is immediately broken by the convenience
that QAPM provides for the rest (data(), headerData(), etc.).

This commit doesn't try and change this in any way, but I'm less and
less convinced of the usefulness of QAPM in its current shape.

it's meant to (e.g. a single-digit seconds field when format ss was

the minimum and maximum for the parser object failed, triggering an
assertion.

In any case, an invalid default-value wasn't useful to the code that
parsed a single section of the date-time string, so brute-force the
current value to a valid date-time (when possible) using the usual
round-trip via milliseconds since the epoch.
