Subject: [PATCH] ext/flac/gstflacdec.*: Remove some unused vars.

Original commit message from CVS:
* ext/flac/gstflacdec.c: (gst_flac_dec_reset_decoders),
(gst_flac_dec_update_metadata), (gst_flac_dec_metadata_callback),
(gst_flac_dec_write):
* ext/flac/gstflacdec.h:
Remove some unused vars.
Do more cleanup of leftover events and tags.
Output tags after the segment event. Fixes #504018.
