Avoids setting this variable multiple times, as each time vout
restart is requested. Also avoids unnecessary vout restarts at
start and when changing profiles.

refs #12063

- add signing of sparkles autoupdate tool
- directly fail on error
- fix bug preventing signing of VLC binary
- rework validation steps so that it validates frameworks and autoupdate
  tool separately, but then the complete bundle like gatekeeper (using
  --deep option)

This interferes with overlay-based outputs, and serves no useful
purpose for VLC since the video frames are always fully opaque.

Remove unused checks for locale.h, machine/parm.h, scsi/scsi.h,
sys/time.h, and sys/ioctl.h. Simplify checks for net/if.h (this has no
dependency) and sys/mounth.h (sys/param.h).

mac frameworks use symlinks for their internal structure. This
reduces size of delivered framework folders by a factor of 3.

Also correctly clean the BGHUDAppkit ressources folder. Info.plist
must remain for proper code signing.

mp4stream tries to build stream with 1.5sec runs.
mp4frag aims files by creating a compatible index.

Might need for transcode tests (fragments are 1.5 sec only).
--sout-x264-keyint=30 --sout-avcodec-strict=-2

Streaming done using http, with fragment start used as iframes.

Close #11740

At least, fedora 20 doesn't enable it.

Can still div by zero by pushing vbr codec

The convention used here matches with the Qt Wayland native platform,
and seems most generic. Note that Wayland does not allow "sharing"
surface handles between multiple display connections in general, and
multiple processes in particular.
