Speex: Add a patch to improve resampler performance.
Add neon optimization and use the full sinc table. This improves
performance by a factor of five on daisy, so we can afford to increase
the quality factor used in cras.
BUG=chrome-os-partner:23275
TEST=(1) build for daisy and parrot (2) run aplay -f dat /dev/zero in one
terminal (3) play 44.1k wav file in another terminal (4) use "perf" to check
cpu used for libspeexdsp.
