f0d6b841a2 matroskademux: improve stream synchronization 
In particular, do not make it send newsegment updates that
sort-of contradict the indented playback segment (e.g. start time).

b527360f21 matroskademux: fix bridging (time) gaps in streams 
As a side effect, avoid sending newsegment updates with start times
that go back and forth, which leads to bogus downstream running_time.

Also fixes seeking in bug #606744.

9bec2b1127 matroskademux: fix stream synchronization 
.. by initializing streams starting at 0, as that is basically
where we 'seek to' at the start and assume streams to start elsewhere.
Also enables newsegment update events for subtitle streams.

01f0a5ce32 avidemux: ignore streams that finished 
When we receive an UNEXPECTED from a stream, move to the next stream and only go
EOS when all streams are EOS. When selecting a stream to push, ignore streams
that went EOS.

avoids a couple of copies of the SDES structure when generating RTCP
packets.

4687199348 rtph264pay: add option to insert PPS/SPS in streams 
Add a new spspps-interval property to instruct the payloader to insert
SPS and PPS at periodic intervals in the stream.
Rework the SPS/PPS handling so that bytestream and AVC sample code both use the
same code paths to handle sprop-parameter-sets. This also allows to have the AVC
code to insert SPS/PPS like the bytestream code.

02960383c1 audiofxbasefirfilter: FFT convolution implementation 
This provides a great speedup, especially the relationship between kernel
length and processing size is now logarithmic instead of linear. Below a
kernel size of 32 it's a bit slower, afterwards it's much faster:

17     0.788000 -> 0.950000
33     1.208000 -> 1.146000
65     2.166000 -> 1.146000
...
4097 107.444000 -> 1.508000

For sizes smaller 32 the normal time-domain convolution is chosen,
for larger sizes the FFT convolution is automatically used.
