audioconvert: resampler: change resample_phase() unit to input samples
...
Report fractional delay in input samples instead of nsec at the nominal
input rate, as that is closer to what the value actually means.

treewide: use SPDX tags to specify copyright information
...
SPDX tags make the licensing information easy to understand and clear,
and they are machine parseable.
See https://spdx.dev for more information.

audioconvert: add resample.prefill option
...
Add a resampler option to prefill the resampler with 0. This then
results in the resampler always outputing and consuming the same
amount of data instead of a short buffer in the beginning.

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.

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.

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.

resample: Let the resampler object handle all channels
...
Move the code to loop over all channels in the resampler itself.
This is better because the resampler can reuse its state for
each channel.
