Intra-only codecs should either be able to read these items from the
bitstream, or they should be set upon codec initialization. In both
cases, syncing these items at runtime is unnecessary.
In practice, this fixes race conditions for decoders that read these
values from the bitstream.
If ret is NULL, a dummy common holder is created to hold *all* the
parallel function returns, which gets written concurrently. This commit
simplify the whole logic by simply not writing to that holder when not
set.
Needed for the C+11 atomics. Also change add_cxxflags to check_cxxflags.

adding demuxer and other logs should be easy
This forces single threaded decoding for simplicity
It also requires pthreads, this could be avoided either with
some lockless tricks or simply by assuming av_log would never be called from
another thread.
