aucat: Add generic channel mapping in place of -j and -c options. The argument to the -m option specifies the source and destination channel ranges to be mapped. Compatibility is maintained: if -m is not used, the -c and -j options still work. Help and suggestions from Jan Stary <hans@stare.cz>, thanks.

Add resamp_getcnt() routine to calculate the exact number of samples that would be consumed and produced by the sampler rate converter. Use it to avoid partial samples that are not properly handled. Fixes last samples of certain files causing aucat to abort.

When resampling, use the exact resampling factor instead of the ratio between input and output block sizes. This was inherited from sndiod, but is not required for files because they are continuous streams of samples and do not need to be split in blocks of equal duration. This change makes playback/recording rate match exactly the requested sample rate.

Make resamp_do() get the exact number input and output samples and provide routines to calculate them. This way we don't rely on it to calculate the bytes procuded/consumed anymore. No behaviour change.

Simplify internals and rewrite file header parsing code: - remove -M, -t, -w, -C, -x flags that don't make sense anymore - make "-j off" the default (sndiod already does the job) - don't limit the number of played/recorded files. - add support for floating-point encoded files. - add support for apple .aiff and sun/next .au files
