Add PosixSignalNotifier utility class to covert POSIX signals to
Qt signals and allow qTox to quit appropriately on Linux, FreeBSD
and macOS.
Might protect from data corruption bugs when application is being
terminated during I/O.
Fixes: #4470
This prevents opening and closing of X11 connection and associated files every 1 second.
X11 connection is used for userAutoAway feature and to read CapsLock status.
Revert needed, since otherwise there is no way to do automatic sorting
of includes.
Also reverted change to the docs, as leaving it would make incorrect
docs.
In case of conflicts, includes were sorted according to the coding
standards from #3839.
This reverts commit b4a9f04f92.
This reverts commit 5921122960.
This adds support for multi-byte builds. Users building qTox in
multi-byte instead of unicode mode would otherwise get compiler errors.
This is one step in the direction of making qTox a library with the UI
being just one application of it: it gives library users a choice of how
they build it.
There is no documentation about what this function is supposed to do or what it
should return, so I'm just guessing it's a success boolean, so it should be
returning true.

We can now get the list of video devices with the dshow ffmpeg device
(so, on Windows). Most of this patch is adapted from libavdevice's dshow
private internal interface, which retrieves useful info but is only
designed to log it to stdout. We reimplement that to get an actual list
of devices names/descriptions, that we can then open with ffmpeg the
refular way.
