ppc: Drop a bunch of unnecessary dsputil_altivec.h #includes
x86: Drop some unnecessary YASM ifdefs

Dead code elimination is enough to avoid undefined references in these cases.
x86: h264_qpel: Simplify an #if conditional

The extra conditions are covered by previous #ifs and conditional compilation.

Support raw dvdsub palette as stored on normal dvd's

This is how the palette is stored on dvd's. Currently
only xbmc passes the palette information to libavcodec
this way.
Check return value of avio_seek and avoid modifying state if it fails

The code still modifies state if the timestamp is not found. Not
sure exactly how to avoid that.
asf hacks
if av_read_packet returns AVERROR_IO, we are done. ffmpeg's codecs might or might not handle returning any completed demuxed packets correctly
added: Ticket #7187, TV Teletext support for DVB EBU Teletext streams
Don't accept mpegts PMT that isn't current
