[Flac-dev] new SEEKTABLE block

I've checked in code that supports a new metadata block called
SEEKTABLE. Basically, it is an optional, arbitrarily-long list
of seek points, by sample number and stream offset. I also added
command-line options to flac so you can specify seek points by
specific sample number and/or a specific number of evenly-spaced
seek points. The table cost about 18 bytes per seek point.
This seems to radically speed up seeks. I should point out a
SEEKTABLE is optional; FLAC doesn't need it to seek but they can
help. And 1% resolution within a stream only costs 1808 bytes.
