[FFmpeg-devel] [PATCH 1/3] lavc/thread: move generic-layer API to avcodec_internal.h

[Anton Khirnov <anton@khirnov.net>]

thread.h currently contains both API for decoder use and functions
internal to lavc generic layer. Move the latter to avcodec_internal.h,
which is a more appropriate place for them.
