761119f640 resample: fix start position of new samples
When we finished processing the history it might be possible that we
need to skip some samples from the input. Implement this by adding
a start offset for the samples in the buffer.

a232e67dd8 resample: completely fill resampler
start with a completely filled resampler so that the first
input byte immediately gives an output sample. When then have
n_taps/2 leading (almost) 0 samples.

Also make the passthrough resampler act like the real resampler
by introducing an n_taps/2 delay.

93006d6d90 resample-native: only do full resample when rate == 1.0
Otherwise choose the interpollating resampler.

2912d2506f audioconvert: improve resampler
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.

dc01b294a2 resample: return the number of consumed samples
We need to return the number of consumed samples, even when we don't
start from the first sample in the buffer.
Add some more logging.

9c8913437b audioconvert: add simple and faster 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.
