The majority of frame-threaded decoders (mainly the intra-only) need exactly one part of ThreadFrame: The AVFrame. They don't need the owners nor the progress, yet they had to use it because ff_thread_(get|release)_buffer() requires it. This commit changes this and makes these functions work with ordinary AVFrames; the decoders that need the extra fields for progress use ff_thread_(get|release)_ext_buffer() which work exactly as ff_thread_(get|release)_buffer() used to do. This also avoids some unnecessary allocations of progress AVBuffers, namely for H.264 and HEVC film grain frames: These frames are not used for synchronization and therefore don't need a ThreadFrame. Also move the ThreadFrame structure as well as ff_thread_ref_frame() to threadframe.h, the header for frame-threaded decoders with inter-frame dependencies.
