Also emit port info the the merger monitor ports.
Proxy params and buffers to the right monitor ports.
fmtconvert does not always have dsp ports
Increase resampler output buffer sizes so that we can up and downsample.
Fix little off by one in native resampler.
Fix passthrough in speex resampler.
Add a sinc based resampler that, unlike speex, avoids memcpy and
works directly on the source data. It also allows for ssse3
optimizations and aligned loads. It will later switch to table
interpolation when doing variable rate.
