A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.

Moved internal_buffer, internal_buffer_count, and is_copy.

Add a decoder for the VBLE Lossless Codec, which
still has a cult following. Used to be popular
several years ago on doom9.

It is found in some 8svx files (e.g. ones created by SoX).
Currently the decoder reuses the 8svx functions because we already have
handling of a single large planar packet for the compressed 8svx codecs.

This extends the lock manager in avcodec to manage two separate
mutexes via the user-specified lock functions.

The documentation for CODEC_CAP_PARSE_ONLY and AVCodecContext.parse_only
indicates that they are utilized through avcodec_parse_frame(), which was
never actually implemented.

It's never been touched or used in any way since it was added in 2003
and only works for PIX_FMT_PAL8, which makes me conclude that nobody's
ever used it.

Deprecate CODEC_FLAG_EXTERN_HUFF

Deprecate CODEC_FLAG2_MEMC_ONLY

Deprecate CODEC_FLAG2_BIT_RESERVOIR

Deprecate CODEC_FLAG2_INTRA_VLC.

Deprecate corresponding global option.

Ideally all x264 private options should be generated automatically, but
x264 doesn't provide the API for this yet.

It's called from avcodec_register() anyway, so there's no reason for it
to be public.

Use AV_PKT_FLAG_CORRUPT flag to mark packets that might be incomplete
or have errors. Formats that have a mean to validate their packets
should use this flag to deliver such information instead of silently
dropping the packets.

Deprecate avcodec_alloc_context/2.

Deprecate corresponding AVCodecContext option.

This is the first test of decoder private options.

Adds support for decoder-private options and makes setting other options
simpler.

Also deprecate avcodec_get_pix_fmt_name() in its favor.

This adds basic stream format support and allows for arbitrary bit rates
rather than just those supported in AC-3.

This will allow audio decoders to support output of different sample formats
as a runtime option.

Also deprecate av_get_pict_type_char() in favor of
av_get_picture_type_char().

The new enum and av_get_picture_type_char() are defined in libavutil.
This allows the use in libavfilter without the need to link against
libavcodec.

It was deprecated only recently.

AVOptions were moved to libavutil only recently.
