Most of the stuff in this init function is global, and thus should be
done via ff_thread_once, and caps_internal should have
FF_CODEC_CAP_INIT_THREADSAFE.

This utility helps avoid undefined behavior when doing things like
checking how much memory we need to allocate for an image before we have
allocated a buffer.

When there are potentially annotation (i.e. metadata) fields to write,
au_get_annotations() is called to produce a string with them. To do so,
it uses an AVBPrint which is finalized to create the string. This is
wasteful, because it always leads to an allocation even if the string
actually fits int
by using av_bprintf() instead of several av_bprint_append().

This av_freep(&key) in conjunction with the fact that the loop condition
