2% faster in function mdct512().

8% faster in function.

Originally committed as revision 26027 to svn://svn.ffmpeg.org/ffmpeg/trunk

Decreases memory usage for less than 6 channels.

Originally committed as revision 26026 to svn://svn.ffmpeg.org/ffmpeg/trunk

This will allow future SIMD optimization of the window function.

Originally committed as revision 26025 to svn://svn.ffmpeg.org/ffmpeg/trunk

Lowers memory usage when encoding less than 6 channels.

Originally committed as revision 26024 to svn://svn.ffmpeg.org/ffmpeg/trunk

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().

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.

Originally committed as revision 26022 to svn://svn.ffmpeg.org/ffmpeg/trunk

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.

The generic default is 0/0 and that obviously triggers once the value is used.

svq3 still doesn't support multithreading, but it's simpler for clients if
they can enable threading for all codecs by default.

Originally committed as revision 26015 to svn://svn.ffmpeg.org/ffmpeg/trunk

This makes it possible to abort a blocking connect call.
