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.

e9fe30ccd1 avcodec/parsers: Add macro to set list of codec ids
The current code relies on AV_CODEC_ID_NONE being zero, so that
unused codec ids are set to their proper value. This commit adds
a macro to set unset ids to AV_CODEC_ID_NONE.

(The actual rationale for this macro is to simplify
the transition to making the private fields that are
currently public in avcodec.h really private.)

b668662939 get_bits: Move BITSTREAM_READER_LE definition before all relevant #includes
This avoids the danger that get_bits.h might get indirectly #included before
BITSTREAM_READER_LE is defined.

Also sort headers into canonical order where appropriate.
