72415b2adb Define AVMediaType enum, and use it instead of enum CodecType, which 
is deprecated and will be dropped at the next major bump.

ef768b0c32 Disallow VLC coding with more than 8 bits as there are several bugs 
in that code that could lead to broken files.
AC coding is unaffected.

5d7bc46c2d Throw out last experimental warning that was printed for colorspaces with more than 
8 bits per component. This does no good except scaring users away.

2ba8301769 Mark all pix_fmts and supported_framerates compound literals as const. 
Makes no difference for gcc but at least icc can put them in .rodata then.

68f8d33bec Support >8bit per component YUV in FFV1. 
decoding becomes slower, encoding becomes faster, with gcc on duron.
some inlining overrides like av_flatten are added to keep inlining similar
to before.

217d34e307 Force speed irrelevant calls to get/put_symbol() to be noinline. 
We need to change decode_line to always_inline because gcc decided not to inline
it anymore once we force some calls to get/put_symbol() to be non inlined and
this decision of gcc would lead to a 10% overall speed loss.
100k smaller object file, no speed change

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
