lavc/dvdsubdec: accept palette from options.

On DVDs, the palette is part of the IFO file and therefore
not available when reading from a dumped VOB file.

pcmdec: move read_packet function to pcm.c so it can be shared with other demuxers

While here remove pts/dts code, it is apparently not needed and cause
problems for demuxers that will use such function.

  lavc: don't reuse audio buffers

This commit causes a 0.5% speedloss for mp3 and 2% for raw pcm, that is
"time ffmpeg" style tested thus includes disk IO, demux and parsing

I would not have merged it if it wasnt required for the "new" buffer API
but sadly it is.
Once the new API is in ill reimplement proper buffer reuse, which will
fix this speedloss. In case we choose not to merge the "new" buffer
API then this commit here should be reverted.
