Add an option to webm_dash_manifest demuxer to specify a value for

the muxer. Fixes an existing FIXME in the code.

  build: Fix dependencies for alsa/jack/sndio support

Added explicit enable (which will be automatically added later on in
ee480790) to actually fix this commit. Without the explicit enables,
alsa, jack and sndio gets disabled.

Also added jack, alsa and sndio to the have list so the HAVE_* are
populated to make (this fixes the SKIPHEADERS chunks).

  vdpau: Do not #include vdpau_x11.h from the main vdpau header
Merged-by: Clément Bœsch <u@pkh.me>

Purpose: avdevice/decklink: Removed pthread dependency by replacing
semaphore used in code appropriately.  Doing so makes it easier to
build ffmpeg using Visual C++ on Windows.  This is a contination of
Kyle Schwarz's "avdevice/decklink: Remove pthread dependency" patch
that is available at https://patchwork.ffmpeg.org/patch/2654/ .  This
patch wasn't accepted, and as far as I can tell, there was no
follow-up after it was rejected.

Notes: Used Visual Studio 2015 (with update 3) for this.

Comments:

-- configure: Eliminated pthreads dependency for decklink_indev_deps
   and decklink_outdev_deps and replaced with threads dependency

-- libavdevice/decklink_common.cpp / .h:
a) Eliminated semaphore and replaced with a combination of a mutex,
   condition variable, and a counter (frames_buffer_available_spots).
b) Removed include of pthread.h and semaphore.h and now using
   libavutil/thread.h instead.

-- libavdevice/decklink_dec.cpp: Eliminated include of pthread.h and
   semaphore.h.

-- libavdevice/decklink_enc.cpp:
a) Eliminated include of pthread.h and semaphore.h.
b) Replaced use of semaphore with the equivalent using a combination
   of a mutex, condition variable, and a counter
   (frames_buffer_available_spots).  In theory, libavutil/thread.h and
   the associated code could have been modified instead to add
   cross-platform implementations of the sem_ functions, but an
   inspection of the ffmpeg source base indicates that there are only
   two cases in which semaphores are used (including this one that was
   replaced), so it was deemed to not be worth the effort.
