75735c4573 audioparsers: add very basic dts/dca parser
Still some issues, e.g. with seekable queries in totem, but also
processing already-chunked input (created with matroskademux ! gdppay).

46ea4eaa1f flacparse: Adjust unit tests to new flacparse behaviour
Garbage after frames is now included in the frames because flacparse
has no easy way to detect the real end of a frame. Decoders are
expected to everything after the frame because only decoding the
bitstream will reveal the real end of the frame.

Fixes bug #631814.

572366e179 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.

bfdc132ad0 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.

6b71b65289 Revert "baseparse: add skip property"
This reverts commit b5a3d60363.

Reverting this for now, since no one really seems to remember why this
property exists or what it could possibly be good for. It seems to have
been in the original mp3parse since the beginning of time and was back-
ported from there.

8ef15e6247 baseparse: Fix debug output
We lose the reference to the buffer after gst_pad_push(), so the debug

0198d6320b baseparse: remove is_seekable vmethod and use a set_seek instead
Seekability, like duration, etc is unlikely to change (frequently), and
the default assumption covers most cases, so let subclass set when needed.
At the same time, allow subclass to indicate if it has seek-metadata (table)
available, and possibly have it provide an average bitrate.
