avcodec/dnxhd_parser: fix parsing interlaced video, simplify code

There appears to be no need to treat interlaced videos differently,
also that code is flawed, as for at least one input cur_field would
be always 0.

avcodec/crystalhd: Adapt to new new decode API

The new new decode API requires the decoder to ask for the next input
packet, and it cannot just return EAGAIN if that packet cannot be
processed yet. This means we must finally confront how we get this
decoder to block when the input buffer is full and no output frames
are ready yet.

In the end, that isn't too hard to achieve - the main trick seems to
be that you have to aggressively poll the hardware - it doesn't seem
to make any forward progress if you sleep.

libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1

Purpose: libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL
is greater than 1.  This is only relevant when thread.h is included by
C++ files.  In this case, the relevant code is only defined if
HAVE_PTHREADS is defined as 1.  Use configure --assert-level=2 to do
so.

Note: Issue discovered as a result of Coverity build failure.  Cause
of build failure pinpointed by Hendrik Leppkes.

Comments:

-- libavutil/thread.h: Altered ASSERT_PTHREAD_NORET definition such
   that it uses av_make_error_string instead of av_err2str().
   av_err2str() uses a "parenthesized type followed by an initializer
   list", which is apparently not valid C++.  This issue started
   occurring because thread.h is now included by the DeckLink C++
   files.  The alteration does the equivalent of what av_err2str()
   does, but instead declares the character buffer as a local
   variable.

avdevice/decklink: remove pthread dependency

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.

Support building C++ files with MSVC

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.
