Andreas Rheinhardt e0b0ca8111 avcodec/avcodec: Schedule moving private fields of AVCodecParser out of avcodec.h
AVCodecParser has several fields which are not really meant
to be accessed by users, but it has no public-private
demarkation line, so these fields are technically public
and can therefore not simply be made private like
20f9727018 did for AVCodec.*

This commit therefore deprecates these fields and
schedules them to become private. All parsers have already
been switched to FFCodecParser, which (for now) is a union
of AVCodecParser and an unnamed clone of AVCodecParser
(new fields can be added at the end of this clone).

*: This is also the reason why split has never been removed despite
not being set for several years now.
