Original commit message from CVS:
* ext/flac/gstflacdec.c: (flac_caps_factory), (raw_caps_factory),
(gst_flacdec_write), (gst_flacdec_convert_src):
* ext/flac/gstflacdec.h:
Add support for flac files with 24/32 bits per sample; and misc.
minor clean-ups. Seeking is still partly broken (for me at least).
