tremor: drop internal tremor library

Drop internal copy of the tremor library. Note that the internal ogg
demuxer (which is still sometimes useful to work around libavformat
ogg demuxer problems, though it's itself quite buggy) now cannot be
compiled without either external libvorbis or libvorbisidec (tremor).
