rtsp: Don't set the RTP time base from the sample rate if no sample rate is set
This also reverts SVN rev 26016, which incorrectly overwrote the time base
with 90 kHz for all streams, regardless of what was set by the SDP parsing.
The stream that triggered the fix in 26016 still works after this commit.

Remove last_samples[] and copy directly from planar_samples[].
Avoids memcpy that was used to store last samples for next frame.
Approx. 3% faster in function deinterleave_input_samples() and reduces memory
usage by 3kB.

SVQ3: Allow decoding if thread_count is > 1
svq3 still doesn't support multithreading, but it's simpler for clients if
they can enable threading for all codecs by default.
