This patchset initially grew out of my dissatisfaction with the fact
that the AVBuffer API contains implicit allocations in av_buffer_ref()
that need to be checked. Later this combined with my dissatisfaction
with the current ThreadFrame API (which contains an implicit
av_frame_ref()) which forbids decoders to set any AVFrame field
of a frame that is used for syncing after having called
ff_thread_finish_setup(). This leads to a race in the vp9-encparams
test that is fixed in this patchset.
