flacparse: Don't parse the complete FLAC frames but only look for valid frame headers
...
Thanks to Felipe Contreras for the suggestion. This is partially
based on his patches and makes flacparse more than 3.5 times faster.
Looking for valid frame headers is unlikely to give false positives
because every frame header is at least 9 bytes long, contains a
14 bit sync code and a 8 bit checksum over the first 8 bytes.
Fixes bug #631200 .

flacparse: Really post tags only after the initial newsegment event
...
The first newsegment event will be send by the first call to
gst_base_parse_push_buffer() if necessary, posting the tags
before that is not a good idea. Instead do it from the
GstBaseParse::pre_push_buffer vfunc.

baseparse: use _set_duration to configure duration update interval

... as it logically belongs there as one or the other; either subclass

flacparse: Optionally check the overall frame checksums too before accepting a frame as valid
...
This is optional because it's a quite expensive operation and it's very
unlikely that a non-frame is detected as frame after the header CRC check
and checking all bits for valid values. The overall frame checksums are
mainly useful to detect inconsistencies in the encoded payload.

flacparse: Check the CRC-8 of the headers before accepting a frame as valid

This makes false-positives during seeking much less likely and detection of
them much faster.

flacparse: Fix buffer refcount issue
...
When called from the GST_FLAC_PARSE_STATE_HEADERS case,
gst_flac_parse_hand_headers() does a gst_buffer_set_caps() on a buffer
with refcount > 1. This change handles this case by making the buffer
metadata_Writable.
