837781db52 Add Qt::ISODateWithMs date format, with support in QTime/Date/DateTime
The Qt::ISODate format strips milliseconds, so a new format is introduced
that keeps the milliseconds. A new format was chosen over fixing the
existing format due to the behavioral change of suddenly having ms
as part of Qt::ISODate.

e80faf3db6 QTimer: don't circumvent <chrono> safety net
By templating on the <chrono> types and unconditionally using
duration_cast to coerce the duration into a milliseconds, we
violate a principal design rule of <chrono>, namely that non-
narrowing conversions are implicit, but narrowing conversions
need duration_cast. By accepting any duration, we allow non-
sensical code such as

   QTimer::singleShot(10us, ...)

to compile, which is misleading, since it's actually a zero-
timeout timer.

Overloading a non-template with a template also has adverse
effects: it breaks qOverload().

Fix by replacing the function templates with functions that
just take std::chrono::milliseconds. This way, benign code
such as

    QTimer::singleShot(10s, ...)
    QTimer::singleShot(10min, ...)
    QTimer::singleShot(1h, ...)

work as expected, but attempts to use sub-millisecond
resolution fails to compile / needs an explicit user-
provided duration_cast.

To allow future extension to more precise timers, forcibly
inline the functions, so they don't partake in the ABI of the
class and we can later support sub-millisecond resolution by
simply taking micro- or nano- instead of milliseconds.

063997f44f QMenu: don't force platform instance creation on construction
There's a conflict between QGtk3Menu and QDbusPlatformMenuBar. The
problem is that on Unity the type of the platform menu instance must
be different depending on whether the menu is in the global menubar or
a standalone context menu.

Since QMenu creates a platform menu instance at construction time, it
does not yet know whether it will be added into a menubar. QMenuBar
checks that the QMenu already has a platform menu instance, and passes
it to the platform menubar. As a result, a QGtk3Menu instance is passed
to QDbusPlatformMenuBar.

Currently, a standalone QMenu does not use the native platform menu
instance. Only menus that are added to a QMenuBar do. Therefore we
don't need to create the platform instance when QMenu is constructed,
but only after it is added to QMenuBar. The platform menu instance
creation is implemented in QMenuBarPrivate::getPlatformMenu(), and
QMenu::setPlatformMenu() calls syncPlatformMenu() to take care of
syncing the QMenu properties and actions to the new platform menu
instance.

The macOS-specific methods QMenu::toNSMenu() and QMenu::setAsDockMenu()
rely on the platform menu instance, and must therefore create it on
demand.

This is a hot fix for the release blocker, not a long term solution.
In the future, if standalone QMenus are made to use native platform
menu instances, the instance must be created lazily when the menu is
about to be made visible.

6a35e77ef3 Change confusing Q_DEAD_CODE_FROM_QT4_FOO define
Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.

This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.

To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

5cc0d92c24 QAbstractItemView: use only a 1x1 QRect for selecting on mouse press
Before commit f1e9076809, mousePressEvent
called the virtual method setSelection(const QRect&, SelectionFlags)
with the 1x1 rectangle which contains only the clicked QPoint, unless
the SelectionFlag "Current" was set because Shift was pressed during
the mouse press.

Since that commit, the behavior has been changed such that the
rectangle is the one that is spanned by the center of the clicked item
and the clicked pixel. In theory, the result should be the same (i.e.,
only the clicked item should be selected), but

* the code path in QListView::setSelection for 1x1 QRects is more
  efficient, and
* using a larger QRect can cause problems with custom views, see the
  comments in QTBUG-18009

This commit ensures that the 1x1 QRect is used again, unless the
SelectionFlag "Current" is used.

... and avoid detach()ing potentially large data for just

A QBitmap differs from a QPixmap (its base class, urgh)
by always having a data != nullptr and a Bitmap pixel
type, yet load() was unconditionally setting 'data' to

Fix by move-assigning a null QBitmap instead of resetting
'data'.

Add some tests.

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.

The solution, of course, would be to use a static_cast here, but
why go via int in the first place? Qt::Orientation can perfectly
well be used in QFETCH, as proven by tst_qmainwindow, among other
things.

c35eff2ace Add qtest_network.h
... and move toString() implementations there which were repeated in
network tests, or #ifdef'ed in qtest.h.

Since the functions moved from network tests are now in a public header,
had to massage them a bit to pass headersclean:

- replace Q_FOREACH with C++11 range-for
- avoid implicit conversion from QByteArray -> const char* (done by
  re-using toString(QByteArray) instead of calling strdup() manually)

Also made the functions overloads instead of specializations. This
allows to pass the enum by value instead of by const-&.

Like the existing QHostAddress, the newly-added toString() overloads are
marked as \internal. We can decide later whether to turn them into
public API.

462f6029ed Fix crash when doing many text layouts with superscript/subscript
After e109b8a0f3, it is possible
that the cache will be flushed as a result of inserting a new
font rather than just when the timer event triggers. When doing
superscript and subscript text layouts, we would first get
a regular font engine, then a scaled one, and then reference
the regular font engine *after* getting the scaled one. If the
regular font engine was deleted as a result of inserting the scaled
one, we would get a dangling pointer and crash.

The situation was improved by 49926bb9ef.
You would now to switch between 256 different fonts in the layout
in order to trigger it. The test in the commit will trigger the
crash even with this change.

[ChangeLog][Qt Gui][Text] Fixed a crash that could happen if you
were doing many different text layouts with different fonts
and superscript or subscript alignment.

da2c73ad2b Plug memleaks in tst_QWidget
We need to delete the style returned from QStyleFactory::create()
ourselves, so put them into a QScopedPointer.

The alternative would have been to create this once, as a member
of tst_QWidget, but this is the minimal approach that ensures
behavior just as the old code, but without the leak.

5571d2bf62 tst_QApplication: Fix UBs (invalid cast) in focusMouseClick()
Found by UBSan:

  tst_qapplication.cpp:1754:48: runtime error: member access within address 0x7ffda11f2220 which does not point to an object of type 'SpontaneousEvent'
  0x7ffda11f2220: note: object is of type 'QMouseEvent'

The code attempted to model the layout of a QEvent with another class
that allows public access to the memory location that (hopefully)
corresponds to QEvent::spont, gaining access by casting a QEvent
object to that specifically-crafted class.

Fix by the using the existing QSpontaneKeyEvent::setSpontaneous()
call, which, despite its name, works for all QEvent subclasses, and
which has already been fixed to not invoke UB (in bc087db).

3379ace11b QDateTimeEdit: synchronize time-spec before initializing display
QDateTimeEdit ignores the time-spec of its date-time value, using its
own time-spec instead; mostly, this works because it first conforms
the value to its own time-spec.  However, during construction, before
doing this, it set up its display data, which could leave it with a
different time (rather than a different representation of the given
time) than it was asked to use.

Moved the updateTimeSpec() calls to immediately after setting value in
QDateTimeEditPrivate::init() to ensure correct handling.  Added test.

158781ff25 QSslSocket: respect read buffer's max size (SecureTransport)
1. QSslSocketBackendPrivate::transmit was ignoring 'readBufferMaxSize';
as a result, we can have a user trying to set read buffer's size
to a small value (and more important - reading slowly in a small
chunks from this socket), but SSL itself socket reading 'too fast',
potentially growing its internal buffer to a huge size. This also
results in auto-tests failing - whenever we're trying to limit read
rate in some test.

2. Update qsslsocket auto-test.

since the spacer is owned by the layout until we remove it).

In distributeMultiCell(), allocate the QStyle subclass on the stack so
the compiler cleans it up properly on all exit paths (was:
unconditional leak).

8cd28ea885 QGuiApplication, platform plugins: don't modify AA_DontUseNativeMenuBar
The default should be false, meaning the application will prefer to
use a native menubar if the platform supports it.  The application
author can set it to true if he wants to always use a Qt-rendered
menubar instead; or, he can call QMenuBar::setNativeMenuBar().
Qt and its plugins should not override the author's wishes.
Instead, if the platform plugin cannot create a native menubar
for whatever reason, createPlatformMenuBar() will return null,
and QMenuBar will fall back to using a Qt menubar instead.
The application can check the result via QMenuBar::isNativeMenuBar().

QMdiArea when maximized inside a QMainWindow with an empty title
does not replace the main window's title if we are using native menus.
This behavior turned out to be the same on Unity as it is on macOS,
so the autotest needed adjustment to expect that behavior whenever
the menubar is native, not only on certain platforms.

tst_QMenuBar::allowActiveAndDisabled() tests a standalone QMenuBar.
In f92f78094 it was disabled on macOS, but on Ubuntu it passes as
long as we force it to be a non-native menubar, so it should pass
that way on macOS too.  Removed unused variable RESET to fix warning.
