7824e87c5b flacparse: On sink caps change restart parser
Draining the parser is not enough here, on caps change we need to
reset it so it is ready to accept new caps.

336a97157c flacparse: Drain the parser when a CAPS event is received
After a CAPS event, in theory a new stream can start and it might start
with the FLAC headers again. We can't detect FLAC headers in the middle
of the stream, so we drain the parser to be able to detect either FLAC
headers after the CAPS event or the continuation of the previous stream.

This fixes for example

    audiotestsrc num-buffers=200 freq=880 ! flacenc ! c. \

d4c04cb079 Revert "flacparse: fix header rewriting being ignored"
This caused broken metadata and also looks a bit dodgy.
Revert until we can figure out a solution that works for
all cases and doesn't break anything.

This reverts commit adeee44b07.

b02350bd62 flacparse: Request at least the full header size when parsing headers
Otherwise baseparse will incrementally send us bigger buffers until the
full header size is reached, which is not only pointless but also means
that baseparse will reallocate and copy into a bigger buffer for every
input buffers. In pull mode that's done in 64kb increments, in push mode
usually in much smaller increments, causing a lot of overhead for
example when parsing high-quality coverart.

29b807685d Revert "flacparse: fix playback if sample number does not start at 0"
This breaks gst-validate on the build server (though not locally),
and a unit test, and I can't run unit tests right now for some
unrelated reason.

This reverts commit 0747b56f8e.

66e9e4c202 Revert "flacparse: push tags in pre_push_frame"
This reverts commit 4065fcb80a.

flacparse should not push tags by itself, the base class is going to do that
while properly merging in upstream tags. It just didn't because of a bug in
the base class, which was hidden by this commit.

Additionally. values 7-126 are currently reserved by the
spec so the situation might change in the future.

8a745837aa flacparse: warn on wishful parsing of weird headers
If we get anything from 7 to 126 as type when parsing
a metadata block header, we are likely dealing with a
FLAC stream version we don't fully understand. Issue
a warning if so.

Document function assumptions regarding the passed-on
type while at this.

0d88f27108 flacparse: set both pts and dts so baseparse doesn't make up wrong dts after a seek
flac contains the sample offset in the frame header, so after a seek
without index flacparse will know the exact position we landed on and
timestamp buffers accordingly. It only set the pts though, which means
the baseparse-set dts which was set to the seek position prevails, and
since the seek was based on an estimate, there's likely a discrepancy
between where we wanted to land and where we did land, so from here on
that dts/pts difference will be maintained, with dts possibly multiple
seconds ahead of pts, which is just wrong. The easiest way to fix this
is to just set both pts and dts based on the sample offset, but perhaps
parsed audio should just not have dts set at all.

e0a5c07e8d audioparsers: use ACCEPT_INTERSECT flag
The parser can accept input that is not completely specified. Use the
ACCEPT_INTERSECT flag on the sinkpad to tweak the acceptcaps function to
check for intersection only. This allows us to proxy downstream
constraints while still allowing non-subset caps as input.
We can then also remove the appended template caps workaround.
Make a unit-test to check the new feature.
