better seeking
Ok, the patch from 2003 about improving seeking still didn't make it
to CVS, so here is another try.
I made some benchmarking with the test_seeking utility from flac
sources to show how bad the current seeking is, especially without
seektable. Track used for the experiment had about 50 minutes.
In the following table is average number of seeks and number of
decoded frames required for one
