Justin Ruggles b6f6204db9 Allocate all large per-channel arrays using av_malloc().
Decreases memory usage for less than 6 channels.

Justin Ruggles aa645b9888 Make windowed_samples 16-byte aligned.
This will allow future SIMD optimization of the window function.

Justin Ruggles e8d21fba3f Allocate planar_samples using av_mallocz().
Lowers memory usage when encoding less than 6 channels.

Justin Ruggles 171bc51c9b Allocate bap and bap1 buffers using av_malloc().
This reduces the memory footprint when using less than 6 channels.
Modify bit allocation to swap the 2 buffers instead of using memcpy() and use
per-block pointers for bap. This is slightly faster (0.3%) in function
cbr_bit_allocation().

Martin Storsjö bbd8f5477d 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.

Justin Ruggles 1c3e117e0b 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.

Luca Barbato a4a3bade0a Reinstate default time_base for rtp streams
The generic default is 0/0 and that obviously triggers once the value is used.

Alexander Strange 0f01602362 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.
