Wraps the SincResampler for multichannel use.  Can't land until after
https://chromiumcodereview.appspot.com/10702050/ lands.

Since the SincResampler unit tests focus on accuracy, the multi channel
resampling tests just ensure the wrapper functions as expected with a
single resampling frequency and a constant fill value.

BUG=133637
TEST=MultiChannelResampler Unittests.
