Start using signalfd where we can. Drop the crash (SIGSEGV, SIGBUS) handling completely.
The crash handling that was in place previously was not async-safe. It also prevented getting
a core dump. So just remove it. There is no safe solution for a single application process since
restoring the keyboard, video modes, etc. all need unsafe calls in the signal handler almost for sure.
We can however improve the handling of non-crash scenarios greatly:
Introduce support for SIGINT, allowing nicely and cleanly restoring the video
mode with the KMS backend when pressing Ctrl+C while QT_QPA_ENABLE_TERMINAL_KEYBOARD
is set.
Same goes for keyboard suspend (SIGTSTP, Ctrl+Z). When QT_QPA_ENABLE_TERMINAL_KEYBOARD is set,
platform plugins now have the possibility to act upon Ctrl+Z. As an example eglfs' KMS backend
is enhanced to handle this by restoring the video mode before suspending the process, and
reinitializing when brought into foreground again (SIGCONT).
SIGTERM is also handled. This is extremely handy when starting an application locally on the embedded
device and then kill-ing it via a remote ssh session. Keyboard and video mode is now cleanly restored.
Finally, when disabling the keyboard, try setting also KDSKBMUTE.

In QFontEngineMulti::stringToCMap() we call the primary engine's
implementation of the same function. If this engine does not support
the character in question, then it's supposed to clear the glyph array,
otherwise there may be left-over junk in the glyph array from previous
script items and the font selection algorithm will think it has already
found a match for the character corresponding to the glyph position.
The freetype engine, for instance, clears the respective entries
in the array when it gets a 0 glyph from the font engine.
In particular, this would happen when you had a ligature preceding
an item that was shaped separately. The ligature (e.g. "fi") would
set the first two slots of the glyph array, but later replace
them with a single glyph. The next item would then get an offset
of 1, i.e. pointing to the position in the glyph array where the
glyph for i was originally contained. If this was not cleared,
it would assume the primary engine supported the character. If
the character was of an unsupported writing system, then you would
get a box in place of it instead.
[ChangeLog][OS X][Text] Fixed appending text with a different
writing system and formatting to a latin ligature.

Use it also in the context initialization code which also relied on pbuffers
until now.
This is safe to do since QOffscreenSurface is deliberately kept minimal: we only
support it for rendering to FBOs or uploading textures, it is quite useless for
any rendering type of operation. Therefore simply not creating a surface when
the extension is available is viable and should not break anything.
While we should have done this a long time ago, the real inspiration now is
to avoid crashes with some bad EGL implementations.
Mesa in particular tends to crash in its interal configuration handling when
trying to create a pbuffer surface with more exotic attributes, for example with
multisampling enabled. Just getting rid of those properties is not an option
since the resulting pbuffer would not be compatible with the existing context.
Therefore our only option is to avoid the pbuffer altogether.
There's a so-far-ignored patch for Mesa http://patchwork.freedesktop.org/patch/38100/
which tries to solve some of this but it turns out it is not sufficient to avoid problems
with the multisampled case. So to avoid more headache, we just stop using pbuffers
there.
[ChangeLog][QtGui] QOffscreenSurface is now relying on EGL_KHR_surfaceless_context when
available, and avoids creating a pbuffer surface when the extension is present.
