Drop assembly for 24-bit fixed-point operations
...
Now i386 compiler is smart enough to generate a single imul
instruction per fixed-point multiplication. This change also allows
24-bit precision to be used on all archs (if -DADATA_BITS=24 is used).
Tested on arm64 by Doug Moss <dougmoss710 at yahoo.com>, thanks

Don't rely on the resampling code to calculate the number of samples

to process, as it may produce one extra sample (to handle accumulation
of fractional samples), which would cause access to one sample past
the end of the buffer and crash aucat. Fix this by limiting the number
of samples processed to a single block.

When resampling, use the exact resampling factor instead of the ration
