fixes #9919

av_set_cpu_flags_mask() is not thread-safe. So are the first call to
av_get_cpu_flags() after loading libavutil, and the first call to
av_get_cpu_flags() after a call to av_set_cpu_flags_mask(). So call
those under the avcodec lock during initialization.

When converting 1920x1080p mp4 using x264, x264 complains that it failed
to allocate memory. This flags makes it happy.

config.h includes vlc_fixup.h that can include stdint.h

The code reads the user-defined settings and adapts channel reordering accordingly,
not the other way around.

vout_macosx: remove misleading user-facing error message about Quartz Extreme being unavailable (close #9777)

While it is strongly desirable to be present, the API behavior or the driver quality seem to have changed on OS X 10.9, so this alert is triggered way to often while video is actually being displayed just fine.

Log message is retained for debugging purposes.

Previously, the is_sleeping flag was not set to true if a deadline was
passed to vout_control_Pop. Consequently, the condition variable would
not be signalled by function vout_control_Wake, called by
vout_PutPicture to give a vout a picture to display. Thus, the vout
would not wake up even when receiving several pictures, instead the
vout waits until the end of the deadline. If the deadline was computed
as the "refresh" deadline from ThreadDisplayPicture, the sleep time
can be as high as 60-70 ms.
