Drop the mpegvideo dependency for svq3 in configure.

Unused buffers scratchpad and temp have been dropped too.

This is done to disentangle ER from mpegvideo. In order to use a
classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function
to set the fields. Please note that buffers need to be allocated before
calling ff_er_frame_end().

For live audio streams, requiring 500 frames for a stream to
be detected is a bit overkill.

This allows live ADTS streams that don't start nicely at
a frame boundary to start up more quickly, e.g.
http://mp3.streampower.be/radio1.aac.

If a portion of the probe buffer seem to resemble ADTS frames,
but some data at the end is a mismatch, disregard the whole
probing attempt. If it actually is ADTS data, there shouldn't be
any mismatches within the sequential frame data.

get_channel() returns 0 on success

mp4 files embedding DVD subtitles do not use the same extradata format
as the rest of Libav expects. The subtitle decoder in libavcodec in
particular does not understand this format.

Convert the extradata to the vobsub .idx format. mp4 stores the palette
as binary 32 bit ints in YUV. The subtitle resolution is stored
separately in the track header, which we access through AVStream.

Group checks into logical groups and sort alphabetically within those groups
unless checks have close coupling. Keep closely coupled checks together.

The function is assigned to a function pointer that does not have the
restrict keyword for that parameter.

This fixes compilation for MSVC builds that don't recognize "restrict",
broken since ed9625eb.

Drop non-informative _bfin suffix, rename some files for consistency with
other architectures, rename others to reflect their content.
