27522fb64c avcodec/put_bits: Relax requirements to rebase PutBitContext 
The earlier requirement was for the new buffer to be bigger than the old
one. This has been relaxed to only demand that the new buffer can hold
all the data written so far. This is in preparation for further commits.

73ee53f317 avcodec/encode: add missing assert to avcodec_receive_packet() 
Encoders must return reference counted packets.

This was checked only for encoders using the AVCodec->encode2() API, while
blindly accepting whatever encoders using the AVCodec->receive_packet() API
were returning.

41b05b849f avcodec/avcodec: Adapt the doc of av_bsf_send_packet to match its actual implementation. 
Explicitly allowing empty packets to signal flushing helps getting rid
of special cases. It does not hinder the ability to send i.e.
timing-only packets, because one can send packets with zero size and
pkt->data set.

004ebd4b added a function with a parameter that was declared as restrict
and not av_restrict. This is not supported by MSVC as several FATE-boxes
that now fail to build show. So use av_restrict.
