07561dbfd1 baseparse: fix seek handling 
Allow a few more seek event type combinations, and really use the result
of gst_segment_set_seek to perform the seek.  Also add some debug.

90753ceb5e baseparse: Don't emit bitrate tags too early 
We wait to parse a minimum number of frames (10, arbitrarily) before
emiting bitrate tags so that our early estimates are not wildly
inaccurate for streams that start with a silence. If the stream ends
before that, we just emit the tags anyway.

While it _would_ be nicer to be specify the threshold to start pushing
the tags in terms of duration, this would introduce more complexity than
this merits.

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.

6663e7c1ca baseparse: Set the last stop to the buffer starttime if the duration is invalid 
...instead of not setting it at all.

af00e59528 baseparse: Send NEWSEGMENT event with correct start and position 
Instead of taking the last stop (which could be buffer endtime instead
of starttime) always take the buffer starttime.

Fixes bug #614016.

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.

76f5d96e06 flacparse: Make bitrate estimation more accurate 
This implements the get_frame_overhead() vfunc so that baseparse can
make more accurate bitrate estimates.

599401a7f9 aacparse: Fix bitrate calculation 
This patch adds the get_frame_overhead() vfunc so that baseparse can
accurately calculate the min/avg/max bitrates for aacparse.

Note: The bitrate was being incorrectly calculated for ADTS streams
(it's not in the header as the code suggests).

88c1e42567 audioparsers: Add bitrate calculation to baseparse 
This makes baseparse keep a running average of the stream bitrate, as
well as the minimum and maximum bitrates. Subclasses can override a
vfunc to make sure that per-frame overhead from the container is not
accounted for in the bitrate calculation.

We take care not to override the bitrate, minimum-bitrate, and
maximum-bitrate tags if they have been posted upstream. We also
rate-limit the emission of bitrate so that it is only triggered by a
change of >10 kbps.

b3f0b029f3 win32: Include config.h before anything else. Fix mpegdemux LIBADD 
Because config.h defines __MSVCRT_VERSION__, which should be defined
before inclusion of any system header.

Also fixes mpegdemux Makefile.am LIBADD typo.

Fixes #606665
