bef57b317f testlib: Deprecate QWARN() in favor of qWarning()
The QtTest best practices documentations recommends using output
mechanisms such as qDebug() and qWarning() for diagnostic messages,
and this is also what most of our own tests do.

The QWARN() macro and corresponding internal QTest::qWarn() function
was added when QtTest was first implemented, but was likely meant as
an internal implementation detail, like its cousin QTestLog::info(),
which does not have any corresponding macro.

This theory is backed by our own QtTest self-test (tst_silent)
describing the output from QWARN() as "an internal testlib warning".

The only difference between QWARN() and qWarning(), besides the much
richer feature set of the latter, is that qWarning() will not pass
on file and line number information in release mode, but QWARN() will.
This is an acceptable loss of functionality, considering that the user
can override this behavior by defining QT_MESSAGELOGCONTEXT.

[ChangeLog][QtTest] QWARN() has been deprecated in favor of qWarning()

3eac6079d9 macOS: Don't mangle QByteArray settings with @ prefix by decoding as UTF-8
QSettings encodes QVariants as @Type(data) strings. If that data contains
a null-byte, we write the string as UTF-8 encoded CFData. When reading it
back we look for a @ prefix, and then pass it as UTF-8 through stringToVariant.

The problem arises then the user writes raw QByteArrays with a @ prefix.
We can detect this situation by checking the result of stringToVariant,
and if it's just a simple conversion of the string into a QVariant, we
know that stringToVariant hit its fallback path due to not finding any
embedded variants.

If that's the case, we return the raw bytes as a QByteArray.

bbc385150f Fix warnings from deprecated posix functions
Windows wants ISO C++ _fileno and _unlink instead of posix fileno and

85416ae6fd Split up the QMetaType unit test
gcc 9 consumed enourmous amounts of memory building the test, regularly
dying on a VM with 4GB RAM. Splitting it up helps.

As a drive-by, use inline static variables, and rename the header used by
other tests to tst_qmetatype_common.h.

9d36032370 Implement QMetaType::canConvert() and use it in QVariant
Use the fact that we return the conversion function as a lambda
to find out reliably whether a conversion between two types
can be done.

This requires some minor adjustments to our tests:

* Nothing can convert to an unknown type and vice versa
* Adjust results to the fact that we don't convert from char
  to QString anymore (where the old method was incorrect)
* QStringList->QString requires some adjustments, as we only
  convert if the string list has exactly one element. For now
  we return true in canConvert(), but the conversion behavior
  in this case is something we should rethink, as it is very
  surprising.

a383d79772 Get rid of QSettings::iniCodec()
Always encodee INI files as utf-8 in Qt6. This is mostly backwards
compatible, as old ini files would encode all non ascii characters.

[ChangeLog][Important behavioral changes] QSettings will now always
encode INI files as utf-8 (and the iniCodec/setIniCode methods are
removed). This is a change from Qt 5 and earlier, where QSettings would
by default escape all non ascii characters. The behavior is equivalent to
what you got in Qt5 by setting a utf-8 iniCodec on the settings object.
Settings files written in Qt 5 will still be readable in Qt 6 (unless
an iniCodec different from utf-8 was used), but to read Qt6 based ini
files in Qt 5 applications, setting the iniCodec to utf-8 is required.

76f53791a1 tst_QSettings: Don't assume the presence of a key means isWritable
The previous sync() of the specific scope and domain may have failed due
to not having the necessary permissions, but the saved value may still be
cached, so we need to check both.

This was observed on macOS Sierra, where a failed sync() will result in
marking the CFPrefsPlistSource as read-only, eg:

f90d6445a0 tst_QSettings: Fix tests on sandboxed platforms such as iOS
WinRT is not the only sandboxed platform. Since it doesn't hurt to keep
the test data in a well known location, we enable the code for all
platforms. We also make sure to mkpath the location, since writableLocation
doesn't guarantee that the location exists.

fd7e00aff5 Don't truncate QDateTime milliseconds when storing QSettings on Apple platforms
The fix is trivial, but the patch adds a new QSettings tests that iterates most
of the QMetaTypes and verifies that storing and retrieving them again gives the
same value. This is a more complete test than the testVariantTypes tests, which
is limited to a subset of the QVariant types. The new tests borrows logic from
the QMetaType test machinery.

QSettings has been Q_ENUM'ified in the process, for improved debug output.

Note that on backends such as the INI backend, the metatype of the QVariant read
from the settings will be a string, so it won't match the input QVariant type,
but the result of converting that to the original value type should still work.

764f5bf48c Apple OS: Handle QSetting strings with embedded zero-bytes
Saving strings with embedded zero-bytes (\0) as CFStrings would
sometimes fail, and only write the part of the string leading
up to the first zero-byte, instead of all the way to the final
zero-terminator. This bug was revealed by the code-path that
falls back to storing e.g. QTime as strings, via the helper
method QSettingsPrivate::variantToString().

We now use the same approach as on platforms such as Windows
and WinRT, where the string produced by variantToString() is
checked for null-bytes, and if so, stored using a binary
representation instead of as a string. For our case that
means we fall back to CFData when detecting the null-byte.

To separate strings from regular byte arrays, new logic has
been added to variantToString() that wraps the null-byte
strings in @String(). That way we can implement a fast-path
when converting back from CFData, that doesn't go via the
slow and lossy conversion via UTF8, and the resulting QVariant
will be of type QVariant::ByteArray. The reason for using
UTF-8 as the binary representation of the string is that
in the case of storing a QByteArray("@foo") we need to
still be able to convert it back to the same byte array,
which doesn't work if the on-disk format is UTF-16.
