3f53c84847 lavc: factor out encoder init/validation from avcodec_open2()
avcodec_open2() is massive, splitting it makes it more readable.

Also, add a missing error code to ticks_per_frame sanity check.

6e7e3a3820 avcodec: add a get_encode_buffer() callback to AVCodecContext
This callback is functionally the same as get_buffer2() is for decoders, and
implements for the new encode API the functionality of the old encode API had
where the user could provide their own buffers.

827d6fe73d avcodec/encode: restructure the core encoding code
This commit follows the same logic as 061a0c14bb, but for the encode API: The
new public encoding API will no longer be a wrapper around the old deprecated
one, and the internal API used by the encoders now consists of a single
receive_packet() callback that pulls frames as required.
