0bb654ed66 baseparse: increase keyframe awareness
... which is not particular relevant for audio parsing, but more so
in video cases.  In particular, auto-determine if dealing with video (caps).

a45019fdd6 baseparse: use correct offset when adding index entry
... bearing in mind that BUFFER_OFFSET is media specific and may not
reflect the basic offset after having been parsed.

76b322a429 baseparse: enhancements for timestamp marked framed formats
That is, as such formats allow subclass to extract position from frame,
it is possible to extract duration (if not otherwise provided)
from (near) last frame, and a seek can fairly accurately target the required
position.

Fixes #631389.

5eeb1f2e1f baseparse: minor fixes and enhancements
Arrange for upstream as well as downstream flushing when seeking.
Also determine upstream size as well as seekability.  Adjust some comments
to reality and employ debug statement in proper order.

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.
