Deprecate avcodec_thread_init()

As a side effect of the last commit, avcodec_open() now calls it automatically,
so there is no longer any need for clients to call it.
Instead they should set AVCodecContext.thread_count.

avcodec_thread_free() is deprecated, and will be removed from avcodec.h at the...

Do not set audio_resample to 0 if audio_sync_method is > 1.

If audio_sync_method is >1 the resampler is used for audio drift
