48286d4d98 avcodec/codec_internal: Add macro to set AVCodec.long_name
It reduces typing: Before this patch, there were 105 codecs
whose long_name-definition exceeded the 80 char line length
limit. Now there are only nine of them.

b9eaf77ed1 avcodec/internal: Move ff_set_dimensions() to decode.h
Decoder-only, as the dimensions are set by the user when encoding.

Also fixup the other headers a bit while removing unnecessary internal.h
inclusions.

66b691f99f avcodec/internal: Move ff_get_buffer() to decode.h
Only used by decoders (encoders have ff_encode_alloc_frame()).

Also clean up the other headers a bit while removing now redundant
internal.h inclusions.

21b23ceab3 avcodec: Make init-threadsafety the default
and remove FF_CODEC_CAP_INIT_THREADSAFE
All our native codecs are already init-threadsafe
(only wrappers for external libraries and hwaccels
are typically not marked as init-threadsafe yet),
so it is only natural for this to also be the default state.

cc0a4fa630 avcodec/vbn(dec|enc): Avoid always-false checks
Do this by switching to bytestream2_(get|put)_le32u() from
bytestream2_(get|put)_le32(); it has after all already been checked
that the packet contains at least a full header, making all
the implicit checks in bytestream2_(get|put)_le32() dead code.

300dd79c3d avcodec/vbn(dec|enc): Avoid leaving stale pointers in context
Therefore move the (Get|Put)ByteContext from the context to the stack.
It is transient anyway.
