Commit 17b73b0d2b regressed performance by grabbing
the entire screen and then copying the grab region.
Move back to grabbing a minimal rectangle instead.
Also handle multi-screen grabs at different device
pixel ratios.
Multi-screen grabbing is handled by grabbing each screen
individually, and then stitching together the result.
The returned pixmap is created using the highest DPR
available, upscaling lower resolution parts as needed.

The only reason why we bundled this library ~6 years ago was because
it was not available on distributions that we supported at the time,
but library was a hard dependency for XCB plugin. See:
2122e731ab
Later more and more projects started to depend on it (compose input
context plugin, libinput, mir, wayland). The configuration had become
too complex, because some projects used bundled and some used the
version from the system.
Having libxkbcommon in 3rdparty sources is not necessary anymore, after
RHEL 6.6 was removed from the list of supported platforms for Qt 5.12.
Ubuntu 16.04 - 0.5.0
Ubuntu 18.04 - 0.8.0
openSUSE 42.3 - 0.6.1
RHEL-7.4 - 0.7.1
This will also simplify further development, e.g. QTBUG-42181
Bumped the minimal required version 0.4.1 -> 0.5.0.
The patch also contains a code marked with "TRANSITION HACK", which
is temporary needed so we can update the dependent wayland module.

The setting is not relevant for modern macOS applications, and none of

The only code path in macOS that picks it up is +[NSFont initialize] in
the UIFoundation framework, storing it for later so that -[NSFont screenFont]
and -[NSFont screenFontWithRenderingMode:] can use it, but these APIs are
deprecated and we don't use them in Qt.
Other NSFont code paths will not hit these APIs unless screen font
substitution is enabled, something it hasn't been since OSX 10.7.

The function doesn't need the flags argument, nor does it need the
ctfont or fontdef arguments if it's a normal const member function.
It can also be used from QCoreTextFontEngine::stringToCMap(), instead
of duplicating the code. This was originally the case before b4aa5d97
which improved surrogate pair handling, but for some reason the change
introduced the duplicate code instead of just changing the arguments
in the function call slightly.
The use of 0xff000000 to skip certain glyphs looks dubious, and is
probably related to QFontEngineMulti's use of the high byte to
indicate which engine the glyph came from, but the multi engine
strips this away before calling out to the concrete engine so
it could potentially be removed in a later patch.

First of all, we were using the wrong size variable: instead of the size
of the section, found in the section header, we were using the size of
each section entry in the section table. Since that's usually smaller,
we weren't hitting a problem.
Second, if the string table is the last thing in the file and there's
nothing else after it, not even padding, then offset + section_size can
be equal to the file size. In fact, the .shstrtab section is usually the
last one, as it contains the section names themselves, so it stands to
reason that it's the second to last thing written.
For generic linkers, the last data in the file is the section table
itself, so usually the file is larger by at least a kilobyte, which is
why we haven't hit this bug. It could only manifest as deciding that
certain specially-crafted but valid ELF files were invalid. I can't
think of a way to trick it into thinking an invalid ELF is valid.
That's another reason why this code needs to be rewritten with more
modern coding styles and actually using <elf.h>

If a focus frame is set around a widget that exist inside a
QAbstractItemView, both the focus frame and the widget will
be scrolled when the table is scrolled (since the focus frame
is a child of the view). The result is that after the widget
has been scrolled (which will move the focus frame to the
correct position as well), the focus frame will be scrolled
next, and therefore away from the widget.
This patch will catch this case by always adjusting the
focus frame position when someone tries to move it. Trying
to move the focus frame away from the widget it tracks
will anyway be flaky.

The previous implementation leads to infinite chain of showing/hidden
line edit under circumstances described in QTBUG-54676. We basically got
the situation when size hint were calculated differently depending on
the line edit visibility state. In this case toolbar layout have to
show/hide extension button and line edit a lot of times and can never
leave this "loop" (please note, that the chain is much more complicated
in reality):
Resize toolbar -> Set layout geometry -> Size is OK to display line edit
-> Set layout geometry -> Hide extension button -> Set layout geometry
(wrong size is calculated here, so "run out of space") -> Hide line edit
-> Set layout geometry -> Show extension button -> Set layout geometry -
> Size is OK to display line edit ... And we're in the "loop"
Clear button is hidden if there is no text in a line edit.
In the previous implementation, the button was always visible, only
opacity was changing in order to "hide" the button. It resulted to
incorrect size hints (regular and minimum).
In the current implementation the button is really hidden/shown, and
size hints calculated correctly.
Also updated unit test for line edit.
