53253a0b83 Simplify asynth sample generation.
One rule can be used to generate all asynth files.
Requires renaming the mapchan files though.
Also switch to using the .wav variants for mapchan
while changing the name anyway, this allows getting rid
of the explicitly specified format.

7521c4bab2 matroska: Clear prev_pkt between seeks.
The new incremental parser doesn't always clear prev_pkt,
however the packet queue is cleared when seeking. Which leads
to a use-after-free.

Verified using Valgrind.

8336eb6f85 matroska: Add incremental parsing of clusters.
Reduces the amount of upfront data required for cluster parsing
thus decreasing latency on seek and startup.

The change in the seek-lavf_mkv FATE test is due to incremental
parsing no longer reading as much data as the old parser and
thus not having that additional data to generate index entries
based on keyframes.  Index entries are added correctly as the
file is parsed.

All FATE tests pass and Chrome has been using this patch for ~6
months without issue.

Currently incremental parsing is not supported for files with
SSA tracks since they require merging packets between clusters.
In this case the code falls back to non-incremental parsing.

269cb6751b mpegts: Try seeking back even for nonseekable protocols
The mpegts demuxer reads 5 KB at startup just for discovering
the packet size. Since the default avio buffer size is 32 KB,
the seek back to the start will in most cases be within the
avio buffer, and will in most cases succeed even if the actual
protocol isn't seekable.

This makes the demuxer startup faster/with less data when
reading data from a non-seekable input, by not skipping
the first few KB.

If it fails, don't warn if the protocol isn't seekable, making
it behave as before in the failure case.
