Change c2c3452ba introduced a new API in Qt to let QPA inform
whether or not shortcuts should be shown in context menus. This
was set to false by default, since by observation, this seemed to
be the most common behavior across platforms. The problem
is that it left no way for the application to override it; The
attribute Qt::AA_DontShowShortcutsInContextMenus simply doesn't work
when shortcuts are always off. And for some application, showing
shortcuts is not just a matter of look-and-feel, but also important
information to be able to use the application the way intended.
This patch reverts the behavior back to how it was in Qt-5.9, where
shortcuts where shown by default (except on macOS where we still keep
them off). It's no so much because the "always off" logic is wrong, but
because there is no (easy) way/work-around for an app developer to switch
them back on (until Qt-5.13, where a new API is introduced to fix the
situation: b1a9a77). And this lack of API can be a show-stopper for some
when upgrading from e.g 5.9 LTS to 5.12 LTS.
This downside of this patch, OTOH, is that it can cause more
change that what is normally wanted in a patch release. But out of
two evils, this is the best option. Those that wan't to hide shortcuts
can set AA_DontShowShortcutsInContextMenus to true, which now will
work.
[ChangeLog][QtWidgets][QMenu] Shortcuts are again shown by default
in context menus, except on macOS. They can be forced off by
setting AA_DontShowShortcutsInContextMenus to true.

The naïve approach used for layer-backing in the past caused a detach
of the backingstore QImage on each beginPaint, since the image was
assigned to the layer via a CGImageRef that participated in the
QImage implicit sharing (and had to, so we couldn't get around that).
We now use IOSurfaces, wrapped in a QPlatformGraphicsBuffer abstraction.
The surfaces can be assigned to the layer's content the same way images
could, but allows us to reason more closely about whether or a buffer
is in use, and increases the chance that we will have a zero-copy path
to the screen.
Unless the window has requested a surface format with single buffering
we use a dynamic swap chain of buffers. In most situations there will
be two buffers in play, one assigned to the layer and one ready to
paint to, but during resize and some other situations the buffers
will grow temporarily to accommodate the increased back-pressure.
Since QBackingStore is documented as having single-buffer behavior,
we take care to persist content between the buffers before every
swap. By doing this before swapping, instead of before each paint,
we can avoid preserving areas that will be painted to anyways, and
will in many situations (such as blinking cursors e.g.) end up not
persisting anything.
The RasterGL surface case is handled by reading out the buffer data
and doing a manual texture upload. In the future we can support
direct texture access via CGLTexImageIOSurface2D, but this requires
QPlatformBackingStore::composeAndFlush to learn how to support other
targets than GL_TEXTURE_2D, as CGLTexImageIOSurface2D only works with
GL_TEXTURE_RECTANGLE_ARB targets.

Remove wrong code changing the Bido level of line separators. This
lead to wrong ordering of the string in case the line separator was
meant to be ignored and the string should be rendered in one line. Line
breaks are anyways already reset to the paragraph level by the algorithm
and reordering is done on a line by line basis, so this will work
correctly when doing proper line breaking.
Secondly fix a small bug found while testing the above change, where
we wouldn't set the correct levels for boundary neutrals and explicit
embedding chars because we did that processing before we were fully
done with the BiDi algorithm.

We translate all pure gray colors into cmyk having c,m,y=0 and only
the k value expressing the darkness. But a fix introduced to avoid
division by 0 caused rgb(0, 0, 0) to be an exception to this; it ended
up being translated as c,m,y,k=1 instead.
Fix by catching the potential div-by-0 situation earlier and directly
set the orthodox cmyk translation: c,m,y=0,k=1.

For some overly tight beziers where the start or end point and the
next control point are closer than the pen width, the stroker's
shifting algorithm will produce a start/end tangent pointing in the
opposite direction from what is expected, for one of the sides. This
would break the square and round capping logic. Fix by detecting the
situation in the capping function and reversing the tangent when
necessary.

When a QRawFont is set explicitly on the layout, we would get certain
font properties from the QTextCharFormat instead. But when the properties
had not been set on the QTextCharFormat, we would get the default values
which were always 0/false, not the actual default values used in QFont.
Instead, we calculate a QFont query based on the format and use the
properties from this. This will give us the correct default values
in the cases where they are not overridden.
