build: Fix dependencies for alsa/jack/sndio support
Added explicit enable (which will be automatically added later on in
ee480790c) 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).

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.

Made appropriate changes to be able to successfully
build C++ files using a Visual C++ build on Windows.
Based on an earlier patch by Kyle Schwarz.
Comments:
-- compat/w32pthreads.h: Made appropriate changes to w32pthreads.h to
get it to build when it is being included in a C++ file and built
with Visual C++. This is mostly a copy of Kyle Schwarz's patch as
described above.
-- configure:
a) Now calling set_ccvars CXX to cause the various CXX_ variables to
be setup properly. For example, with MSVC (Microsoft Visual C++),
this causes CXX_O to be set to -Fo$@ instead of using the default
value. The default value does not work with Visual C++. This
change will also have the impact of correcting CXX_O (and possibly
CXX_C) for other compilers, although this is really only relevant
for the Intel compiler, in addition to MSVC.
b) Now using cl for the C++ compiler for the MSVC toolchain. This is
currently only relevant for building the
Blackmagic/Decklink-related files under avdevice.
