ed7f77071d Replace custom type traits with std one's
Remove most type traits from qtypetraits.h, but keep the custom
implementation of is_signed/is_unsigned. This gets rid of
BSD-3 licensed code from Google in a public header (hugh!).

The custom implementations for is_signed/is_unsigned are kept
because the implementations in gcc's standard headers do not
work as we expect for enums - both is_signed and is_unsigned
always returns false there - see also
  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59027

[ChangeLog][QtCore][General] Qt now relies on type traits from
the C++ standard library.

95d1273548 Windows: Don't claim bitmap fonts support all standard sizes
We were throwing away important information by claiming that all
fonts support all the standard sizes in QFontDatabase on Windows
This caused the font dialog to list unsupported sizes for bitmap
fonts, unlike the native font dialog.

We would also claim to support creating bitmap fonts at
unsupported sizes, which would lead to
1. QFontInfo(font).pointSize() would return the requested size,
not the actual rendered size.
2. Bitmap fonts created at 64 pixels and higher would be invisible.

On Mac, there are no system bitmap fonts, and the use is not very
common, but installing some bitmap fonts on the system, it does
seem to ignore the sizes supported in the font and just displays
the standard list instead, so we keep the current behavior there.

[ChangeLog][QtGui][Text] Fixed list of supported sizes for
bitmap fonts on Windows.

cee4d0c0b7 Add a resetClean() method to the undo stack
With the current API it is not possible to reset the
index into -1. We have setClean() method, but
we are lacking setDirty(). This is needed
in case when the document has changed outside
of the editor and nothing has changed
in the undo stack history. In this case we
don't know the state of the file modified
externally so we need to mark that editor's
contents is different from the file contents
and undoing or redoing commands can't bring
the editor to the clean state.
This may also be useful to call it when
we created a new document and haven't saved
it yet or when the document was restored
from backup file.

e70e168abb Plug leaks in tst_QWizard
This completely over-engineered piece of code has a hierarchy of
Operation subclasses encapsulating but three actual operations
on a QWizard.

Because these operations and their containers were all allocated
on the heap, but never deleted, asan went crazy and reported over
50 leaks (not the record so far, but a (distant) second).

Since these collections are passed through addColumn/QFETCH, too,
it's nearly impossible to track their lifetimes. So instead of
trying, delegate that to the runtime, ie. pack the Operation
objects into QSharedPointer and pass around those instead.

080daae7cd Plug new leaks in tst_QFormLayout
The new takeRow() functions return a pair of pointers to
QLayoutItems and, as the name particle 'take' suggests,
releases ownership of these layout items. Which in turn
means that the caller of the function is supposed to deal
with them.

This was not done here.

To fix, write a RAII class that takes ownership of the
returned layout items, deleting them when it goes out of
scope or gets a new value assigned (only move special
member functions are implemented, making the class move
-only).

Deleting the QLayoutItems is not so easy, though:
QFormLayout has a special function for clearing the
QLayoutItems out, so it appears that just calling their
destructors is not going to fly (though I don't know off
the top of the head why that should be a problem).

Solve this, for now, by adding the layout items back into
a temporary QFormLayout for destruction.

512934f7e7 HTTP/2 - fix the handling of PUSH_PROMISE
HTTP/2 allows a server to pre-emptively send (or "push") responses (along
with corresponding "promised" requests) to a client in association with a
previous client-initiated request. This can be useful when the server
knows the client will need to have those responses available in order
to fully process the response to the original request.

Server push is semantically equivalent to a server responding to a request;
however, in this case, that request is also sent by the server, as a
PUSH_PROMISE frame.

The PUSH_PROMISE frame includes a header block that contains a complete set
of request header fields that the server attributes to the request.

After sending the PUSH_PROMISE frame, the server can begin delivering the
pushed response as a response on a server-initiated stream that uses the
promised stream identifier.

This patch:
- fixes the HPACK decompression of PUSH_PROMISE frames;
- allows a user to enable PUSH_PROMISE;
- processes and caches pushed data for promised streams;
- updates auto-test - emulates a simple PUSH_PROMISE
  scenario.

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.

4cb614c7ab 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.

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.

f6498fd677 Plug more than 4k leaks in tst_QGraphicsView
The vast majority is due to leaking styles in a data-driven
test with almost 100 rows (scrollBarRanges()).

Fix by creating the style into a QScopedPointer.

The remaining ~500 leaks were due to leaked QGraphicsScenes.
They had no parent, and QGraphicsView::addScene() does not
adopt them.

Fix those by passing the resp. view as their (QObject) parent.

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.

f9acbaccde QPixmap::load: ensure QBitmap stays a QBitmap even on failure
... and avoid detach()ing potentially large data for just
preserving the QPlatformPixmap::pixelType().

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
nullptr on failure, turning a QBitmap into a non-QBitmap.

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

Add some tests.

There are no source or binary compatibility guarantees for the QPA classes,
meaning the helper function in QPlatformNativeInterface can be removed.

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.
