sndiod: Use the channel mapping code of aucat

For now sndiod uses only a subset of the available channel mappings.
It gives the same result as the previous one, but having the same
in both programs makes code review and testing easier.

algorithm makes code review and testing easier.

Use a 8-th order FIR low-pass filter for resampling

noise in most practical use-cases.

Remplace aucat server by a new sndiod daemon aimed to be simpler
smaller and faster than aucat. It's a drop in replacement with the
following exceptions that don't affect the default setup:
  - The sample rate and the encoding are a per-device parameters
    thus -r and -e options must precede the corresponding -f option
  - MIDI thru boxes are dynamically created and no -M option
    is required anymore, so -M was removed.
  - MIDI ports are exposed with a new ``midi/N'' name, rather
    than abusing MIDI thru boxes.
