It is implemented for win32 and when sched_getaffinity() is available.

It is cleaner. Also, it seems that ffmpeg-mt correctly handles it
and so will allow using it.

aout_Restart() is quite buggy (IMHO) and restarts the audio output
from the interface thread. Then Qt4 external dialogs are buggy as
they deadlock if called from the interface thread (I cannot find a
direct way to use BlockingQueuedConnection for foreign threads and
DirectConnection for the interface thread).

Until either or both of those bugs are fixed, we cannot use modal
dialog from the audio output.

It is a bit safer.

Close #3439

The XCB/XVideo (for a long time) and the XCB/X11 (since the commit
before the previous one) video output plugins will fail safe in case
the embedding window has an alpha channel. In VLC 1.0, the Xlib plugins
needed this hack as the Xlib error handler would terminate VLC.

If compositing is in use, VLC will now use GLX. This will require
software chroma conversion from YUV to RGB. Also, unless the GLX output
is explicitly selected, VLC will flash twice before it starts rendering.
First, it tries (and fail) to use XVideo, then plain X11. To fix this
cosmetic problem, we would need to keep the window across plugins.

I assume this change is needed to fix #3581, but I have not tested, so
it may or may not be sufficient.

Neither of them support YUV. But GLX is much more likely to work than
FB, and also fails in a safer way.

VLC does not currently handle color masks for ARGB chromas, so this can
not work yet. Instead, fail safe to the GLX output.

It fixes #3522.
