- hardcode the processing chain (it used to be setup dynamically)
- merge simpler processing code from sndiod
- remove -M option, aucat is not a midi tool, sorry.
- remove -t flag (redundant with -q flag)
- remove -w flag (makes sense for server mode only)
- remove -C flag (necessary for full-duplex streams only)
- remove -x flag (xruns already handled by sndiod)
- make "-j off" the default (sndiod already does the job)
- don't limit the number of played/recorded files.
- stream definitions (-ios) now must follow devices definitions they
are attached to (-fMn).
- the -n option is now a special "loopback" device and is thus used
like -f, eg it must precede streams
- channel numbers (-Cc options) correspond always to channel numbers
of the hardware.
- removed -u option (not needed anymore)
