avcodec/parser: move parsers list and related API to its own file And add it to the CONFIGURABLE_COMPONENTS list in Makefile. This way, changes to the new file will be tracked and the usual warning to suggest re-running configure will be shown.

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 20f972701806be20a77f808db332d9489343bb78 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.
