Fixes ticket #883

FourCC CYUV can be Creative YUV and uyvy422 rawvideo.

Avoid unsupported pix_fmts by upscaling chroma.

Fixes ticket #878.

This issue was discovered while decoding the FATE sample vqa/ws_snd.vqa.
For some unknown reason only audio decoding is tested by FATE for that file,
but not video.

Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

This fixes compilation failures related to START_TIMER/STOP_TIMER macros and
-Werror=declaration-after-statement.  START_TIMER declares variables and thus
may not be placed after statements outside of a new block.

Make use of the experimental framesize enumeration ioctl if available.

Unbreak direct streamcopy.

Check capabilities directly in the function, further simplify the code.

Only mmap is supported.

Video4linux2 supports both interlaced and non-interlaced mode, do not
ask for interlaced if not necessary.

Fixes an invalid free() with ass in avi. The sample in bug 98 passes
parts of AVPacket.data as buffer for the AVIOContext. Since the packet
is quite large fill_buffer tries to reallocate the buffer before doing
nothing. Fixes bug 98.
