The move of avio_seek in avi_read_seek is to avoiding modifying
state if the seek would fail.

This reduces problems when underlying protocol is not
seekable even if marked as such or if the file has been
cut short.

mpegts: When playing mpegts over rtp/rtsp/sdp, lavf must still read PAT/SDT to get available streams

The code path using for mpegts over rtp doesn't open the demuxer using
mpegts_read_header,
so it never starts listening for PAT/SDT, only uses auto_guess

This changes so we assume EOF when we can't find the next
streams index entry for non interleaved file.

This uses the RIFF header stored size to figure out the expected AVI file size, instead
of the actual file. To work fully it requires handling failed avio_seek() instead
of assuming they always succeed.

Some fate file has been cut off and contains half a frame at the end which previously
was not output during demuxing. This frame is now output to encoder, thus fate
diff update.

Also trim some redundant stream specifiers descriptions.

They are misleading and carry no useful information.

Add a per-stream -filter option, make -vf an alias for -filter:v. Move
vfilters to the options context.

It's redundant -- -flags +psnr does the same thing.

It's only shadowing the AVOption with the same name.

Also remove redundant -pix_fmt list syntax, it's inconsistent and  only
makes the code more complicated. -pix_fmts should be enough for
everyone.
