This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.

It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.

Adding the thread count in frame level multithreading to has_b_frames
as an additional delay causes more problems than it solves.
For example inconsistent behaviour during timestamp calculation in
libavformat.
Thread count and frame level multithreading are both set by the user.
If the additional delay caused by frame level multithreading needs
to be considered in the calling code it has all information to take
it into account.
Should it become necessary to calculate a maximum delay inside
libavcodec it should be exported as its own field and not reusing
an existing field.

Based on a patch by Michael Niedermayer.

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.

The existing flags prior to this have a semantically different meaning and cannot be
used.

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

AVCodecContext.delay which was previously unused for decoders and fits better.

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.

Add a wrapper for libutvideo's decoder.

This supports decoding the following FOURCCs:
    ULY0 - 4:2:0 YCbCr
    ULY2 - 4:2:2 YCbCr
    ULRG - RGB
    ULRA - RGBA

Also, bump version.

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.
