5a8052f9c1 Activate tst_qxmlstream for Android
tst_qxmlstream was disabled because it crashed. It does not any more.
But it extracted an input zip archive in-place, which is not
possible on Android. To resolve this, input files are
copied to a temporary directory first.
Also, input directories were given to rcc. rcc has a problem
with recursive directories. To circumvent this,
the file list is created in CMake and then given to rcc.

6e9a3d4209 QSettings: support reading UTF-8 keys in INI files
[ChangeLog][QtCore][QSettings] The INI file reader now supports
keys encoded with UTF-8, as well as the %-encoded format. Writing
the keys back to the INI file is still done using %-encoded format.
This change does not touch the way the *values* are handled - they
are both read and written in UTF-8.

Drive-by: remove misleading comments from the reading algorithm.

e99417106f QJsonObject::erase: erase unnecessary and wrong code
Commit 35adb74ddd ("Reimplement JSON
support on top of Cbor") accidentally forgot to multiply by 2 the index
stored in the QJsonObject::iterator. The same mistake was propagated
when QJsonObject::iterator was converted to QJsonValueRef. This had no
ill effects because the o->elements container would always contain more
elements, but it meant the check was ineffective and meant nothing.

So instead of doing nothing when the iterator does not point to this
container, simply assume it does. Bad things will happen if you try to
erase an iterator that points to another container, but that's true for
almost all container/iterator mechanisms.

Drive-by modernization of some of the surrounding lines.

04dc959d49 Introduce Q{Json,Cbor}ValueConstRef
I screwed up when I wrote QCborValueRef by not having the ConstRef
type. The code worked, but it wasn't const-correct, allowing you to
write:

  const QCborArray &arr = something();
  *arr.begin() = QCborArray();

This mistake was brought over to QJsonValue in Qt 6.0, so it has to be
fixed for QJsonValue too. The actual fixes are in the next couple of
commits.

This change is believed to be binary-compatible: the Q{Json,Cbor}ValueRef
classes continue to have the exact same size, except that they're now
empty and have a new base class. They weren't trivial before this commit
doesn't change that.

[ChangeLog][Potentially Source-Incompatible Changes] The iterator
classes for Qt's JSON and CBOR containers (array and map/object) had a
const correctness issue which allowed a const_iterator to mutate the
container being iterated on, even if that container was itself const. Qt
6.4 has a fix for this, but will cause compilation issues where
QCborValueRef and QJsonValueRef were used where the correctness could be
violated. To keep code compiling with both 6.3 and 6.4, either change to
non-const iteration or replace the QxxxValueRef with a const QxxxValue
reference. This change is binary-compatible.

29fceed2ff QProcess/Unix: ensure we don't accidentally execute something from CWD
Unless "." (or the empty string) is in $PATH, we're not supposed to find
executables in the current directory. This is how the Unix shells behave
and we match their behavior. It's also the behavior Qt had prior to 5.9
(commit 28666d167a). On Windows, searching
the current directory is the norm, so we keep that behavior.

This commit does not add an explicit check for an empty return from
QStandardPaths::findExecutable(). Instead, we allow that empty string to
go all the way to execve(2), which will fail with ENOENT. We could catch
it early, before fork(2), but why add code for the error case?

See https://kde.org/info/security/advisory-20220131-1.txt

[ChangeLog][Important Behavior Changes] When passed a simple program
name with no slashes, QProcess on Unix systems will now only search the
current directory if "." is one of the entries in the PATH environment
variable. This bug fix restores the behavior QProcess had before Qt 5.9.
If launching an executable in the directory set by setWorkingDirectory()
or inherited from the parent is intended, pass a program name starting
with "./". For more information and best practices about finding an
executable, see QProcess' documentation.

ec03db7bb3 Fix C++20 ambiguous relational operators between QJsonValue{,Ref}
In C++20, any given relational operator is also considered in its
reversed form, so e.g.

   given op==(X, Y)
   and X x, Y y, then y == x will compile, by using the reversed op(X, Y)

This, unfortunately, makes some existing asymmetric operator overload
sets ambiguous, and instead of applying tie-breaker rules, at least
Clang is warning about these.

For us, this means we need to make our overload set non-ambiguous. The
QJsonValue{,Ref} classes failed this, because they only provide the
following member-operators:

- QJsonValue::op==(const QJsonValue&) const
- QJsonValueRef::op==(const QJsonValue &) const

For member functions, there are no implicit conversions on the LHS. So
in C++17, we have a nice dichotomous overload set:

- LHS is QJsonValue -> use QJsonValue::op==(QJsonValue)
- LHS is QJsonValueRef -> use QJsonValueRef::op==(QJsonValue)

In both of these, it the RHS is a QJsonValueRef, it's implicitly
converted to QJsonValue for the call.

Enter C++20, and the reversed signatures are suddenly available, too,
which is a problem for QJsonValueRef <> QJsonValueRef, which could be
resolved, as in C++17, using

  lhs.QJVR::op==(QJV(rhs))

or it could now be

  rhs.QJVR::op==(QJV(lhs)); // reversed

Says Clang 10:

  tst_qtjson.cpp:990:5: warning: ISO C++20 considers use of overloaded operator '==' (with operand types 'QJsonValueRef' and 'QJsonValueRef') to be ambiguous despite there being a unique best viable function [-Wambiguous-reversed-operator]
    CHECK(r0, a0, r1);
    ^     ~~      ~~
  qjsonvalue.h:189:17: note: ambiguity is between a regular call to this operator and a call with the argument order reversed
    inline bool operator==(const QJsonValue &other) const { return toValue() == other; }
                ^

A similar argument makes op!= ambiguous.

Says Clang 10:

  tst_qtjson.cpp:988:5: error: use of overloaded operator '!=' is ambiguous (with operand types 'QJsonValueRef' and 'QJsonValueRef')
    CHECK(r0, r0, r1);
    ^     ~~  ~~
  qjsonvalue.h:190:17: note: candidate function
    inline bool operator!=(const QJsonValue &other) const { return toValue() != other; }
                ^
  qjsonvalue.h:189:17: note: candidate function
    inline bool operator==(const QJsonValue &other) const { return toValue() == other; }
                ^
  qjsonvalue.h:189:17: note: candidate function (with reversed parameter order)

To fix, provide the missing operators as free inline functions (so Qt
6.2 and 5.15 don't get new symbols added) so there's always exactly
one best match.

This is a fix for 6.2 and 5.15. At the time of writing, 6.3 isn't
released, yet, so there, we could QT_REMOVED_SINCE the pre-existing
member operators in favor of hidden friends (as per QTBUG-87973).

Use C++17'isms to prevent an automatic merge to 5.15, which requires

   contains(QT_CONFIG,c++2a):CONFIG += c++2a

added to tst_qtjson.pro.

(libc++, even in C++20).

Use the idiomatic check (#if defined(foo) && foo >= x) instead,

830fd1908b Add some more QDate::{start,end}OfDay() tests
While investigating an assertion failure I noticed that the existing
tests didn't even exercise these methods for local time or zone time.
Of course, we can't robustly test these time-specs, due to vagueries
of offset details and zone availability, but we can at least verify
that they return date-times on the specified date. Add a test-case for
the start of 1900, on which the assertions were first seen; it is the
earliest moment representable with tm_year >= 0, after all.

One of these tests fails on 6.2 but the fix for that (as opposed to
the the assertion) requires 6.3's improvements to the handling of
time_t's fuller range - too risky a change to pick back to 6.2.
