d4cdc45426 Fix QMetaMethod::invoke and automatic type registration
This was simply not working for two reasons:
 - The index passed to QMetaObject::metacall was not right (there was an offset
   because of the return type)
 - If the registration succeeded, the arguments were not even initialized.

The tests in tst_moc always called QMetaMethod::parameterType before calling invoke,
which was properly registering the type. So this was not seen in the tests before.

[ChangeLog][QtCore][QMetaMethod] Fixed crash in invoke() with QueuedConnection and
types whose metatype gets automatically registered.

dfc2a4a537 QLoggingRegistry: remove rules vector
It only contained a concatenation of the individual rule sets,
probably to fix their order in a central place, as well as
simplifying iteration in defaultCategoryFilter().

Fix these two issues differently, but introducing a RuleSet
enum that lists rule sets in the order in which they should
be applied by defaultCategoryFilter(), and turn individual
rule sets vectors into a C array of vectors.

This enables two nested loops in defaultCategoryFilter to
replace the one loop over 'rules'. Apart from building up
'rules' in updateRules(), this was the only access to that
member. That leaves updateRules() with just the task of
running defaultCategoryFilter() on the new rule sets.
Consequently, a call to updateRules() can now replace the
identical loop in installFilter().

Performance should not suffer. Iterating over a fixed-size
array of vectors is hardly any slower than iterating over
a single vector, and while the construction of 'rules'
was probably a one-off task in most programs, this way
of keeping the rules also saves memory because rules are
not kept in two different vectors.

It is also more maintainable, of course.

0794d61c82 QMetaType: fix the test
8a375341cf added swap() to QJson* classes
and marked them shared-not-movable-until-qt6.

This change made QMetaType start reporting that QJson* classes were
movable; however, the test used QTypeInfo and not QTypeInfoQuery to
double check that information.

Port the test to QTypeInfoQuery.

126c4eae84 Split Q_COMPILER_UNICODE_STRINGS: add Q_STDLIB_UNICODE_STRINGS
Since commit bf2160e72c, we can rely on
charNN_t support in all compilers except MSVC 2013, and since that
commit, we use (in 5.10, not 5.9, yet)

  !defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS)

when we only need charNN_t, the type, as opposed to its library
support (u16string, char_traits<char16_t>, ...).

This patch splits the Q_C_UNICODE_STRINGS macro into two, adding
Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving
Q_C_UNICODE_STRINGS for when we need just charNN_t support.

In QDebug, when constructing a QChar out of a char16_t, cast to ushort
first, since QChar(char16_t) was only officially introduced in Qt 5.10.

[ChangeLog][Potentially Source-Incompatible Changes] The internal
Q_COMPILER_UNICODE_STRINGS macro is now defined if the compiler
supports charNN_t, even if the standard library does not. To check for
availability of std::uNNstring, use the new Q_STDLIB_UNICODE_STRINGS
macro.

924b02aecb Revert "Initialize QLoggingRegistry rules on first use, not qApp construction"
This reverts commit 47cc9e23a3.

We use QCoreApplication::applicationDirPath in the logging initialization to find
a possible qtlogging.ini file. Because QCoreApplication::applicationDirPath requires
a QCoreApplication instance this leads to a qWarning, which in turn leads to a
recursive call to the logging initialization, and in turn to a recursive mutex deadlock.

9a0d47bcf1 tst_largefile: fix the mapOffsetOverflow case to match actual behavior
Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
 The system shall always zero-fill any partial page at the end of an
 object. Further, the system shall never write out any modified portions
 of the last page of an object which are beyond its end. References
 within the address range starting at pa and continuing for len bytes to
 whole pages following the end of an object shall result in delivery of
 a SIGBUS signal.

However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).

Windows MapViewOfFile never allows mapping beyond the end.

5c724a6087 QChar: fix ambiguous comparisons with 0, '\0', ... for good
Commit e0ea0f6178 optimized QChar <->
QString(Ref) comparisons by adding more overloads to avoid creating
QStrings from QChars just to compare them.

But these new overloads made existing comparisons to QChar ambiguous.
This was known at the time for QChar/int comparisons.

It has since turned out that also comparing to '\0' is ambiguous,
ie. not comparing to int or char per se is ambiguous, but comparing to
nullptr constants is, because QString(const char*) is just as good a
candidate as QChar(char)/QChar(int).

Since we allow QString/QChar comparisons, it seems logical to solve
the problem by adding QChar<->nullptr overloads.

[ChangeLog][QtCore][QChar] Disambiguated comparisons with nullptr
constants such as '\0', which 5.8.0 broke. As a consequence,
QChar<->int comparisons are no longer deprecated, as this was a failed
attempt at fixing the ambiguity.

16d1ddfc42 moc: Support signals that return movable-only type
By adding std::move where it makes sense.
This is not only good for move-only types, but for any type which
can be moved as it saves copies of the return value in any case.

[ChangeLog][moc] Move-only types are now supported as return types
of signals and slots.

75f5e2bef2 Deprecate QString::null
It's a Qt 3 compatibility vehicle, and as such inherits the now-alien
property to distinguish empty and null strings. Particularly worrisome
is the following asymmetry:

   QString("") == QString::null          // false
   QString("") == QString(QString::null) // true

Instead of fixing this behavior, recognize that people might use it as
a weird way to call isNull(), albeit one that once was idiomatic, and
simply deprecate everything that deals with QString::null.

[ChangeLog][QtCore][QString] QString::null is now deprecated. When
used to construct a QString, use QString() instead. When used to
compare to a QString, replace with QString::isNull().

b52b509ae4 QLockFile: Don't deadlock if the lock file has a mtime in the future
Stale Lock files in the future can happen in some situations. For exemple
two computers with different clocks access the same file system. It could
be that one of the timestamp is totaly off (several years into the future).

[ChangeLog][QtCore][QLockFile] Fixed a deadlock occurring if a corrupted
lock file's modification time is in the future.

ef26467eb2 Reintroduce a directed QMetaType::typeName array
Commit fb376e0fcc removed an array that
facilitated returning the names of built-in types, to avoid the jump tables
from the switch statement. This commit brings it back but makes the array a
compile-time constant string offset table.

The array is created by way of a set of C++11 constexpr functions, so we
require that compiler feature. I've tested that MSVC 2015 does support
it as well as the ICC 17 when masquerading as MSVC 2015, so I've enabled
for that too. The only compiler left out is MSVC 2013.

If we didn't need to support MSVC 2015, this could have been written
more simply with C++14 relaxed constexpr.

This also adds unit tests to confirm that QMetaType::typeName() does
return null when we said it would. We're testing QMetaType::User-1
(which we'll likely never use) and QMetaType::LastWidgetsType-1 to
select something inside the range of the built-in types.

Let's take the beginning of the description: WaitForSingleObjectEx can
be up to 16 milliseconds early. This is proven by the fact that there
are tests doing:

    wait(waitTime);
    QVERIFY(timer.elapsed() >= waitTime - systemTimersResolution);

and failing.

6797570a59 Fix UB in QFutureInterface: invalid casts from ResultStoreBase to ResultStore<>
ResultStore never actually exists, only ResutStoreBase does. So casting to
ResultStore<T> and calling its  member functions is UB. Put the type dependent
function as template member functions within ResultStoreBase and so we don't
need QtPrivate::ResultStore anymore.
Same goes for the iterator.

d6330a19b2 Use QT_CONFIG(library) instead of QT_NO_LIBRARY
For the windows file system engine, we add an extra macro to use
library loading if configured to do so, but avoid it on WinRT, as
none of the symbols would be found.

We also QT_REQUIRE_CONFIG(library) in the library headers and
exclude the sources from the build if library loading is disabled.
This, in turn, makes it necessary to clean up some header inclusions.
