64407ca94b 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.

396501784c 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.

7e581aebe2 flacparse: Fix uninitialized variable compiler warnings
These warnings are wrong, the variables are only used if they were
initialized by the bit reader.

13f85c8f11 baseparse: use _set_duration to configure duration update interval
... as it logically belongs there as one or the other; either subclass
can provide a duration, or an estimate must be made (reguarly updated).

09223cc719 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.

9fa738d36b 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.

cc6c4ef00b 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.

This implements the get_frame_overhead() vfunc so that baseparse can
make more accurate bitrate estimates.
