This adds tons of code for no other benefit than making VideoToolbox
support conform with the new hwaccel API (using hw_device_ctx and
hw_frames_ctx).
Since VideoToolbox decoding does not actually require the user to
allocate frames, the new code does mostly nothing.
One benefit is that ffmpeg_videotoolbox.c can be dropped once generic
hwaccel support for ffmpeg.c is merged from Libav.
Does not consider VDA or VideoToolbox encoding.
Fun fact: the frame transfer functions are copied from vaapi, as the
mapping makes copying generic boilerplate. Mapping itself is not
exported by the VT code, because I don't know how to test.

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.

This avoids potential undefined behavior in debug mode while still allowing
developers which want to check for potential additional overflows to do so
by manually enabling this.
