bb63198e8b prefill with silence the buffer when cmap_copy() stores samples 
rather than the slot/client buffer. Fixes initialized data being
treated as recorded samples when resampling and/or format
conversions are involved.

b06285beda Prefill with silence rec buffer. 
This is necessary as certain channels may not receive samples,
for instance when mono->stereo conversion is disabled.

7ddb1a5fe5 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.

Found by and help from Michael W. Bombardieri <mb at ii.net>. Thanks.

00ffc8f5ab 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.

028bb6e60d When resampling, use the exact resampling factor instead of the ration 
between input and output block sizes.  This was inherited from sndion,
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.

b347c52869 Flush rec buffer if there's less than one block space left and fill 
play buffer if there's less than one block of data left. No behaviour
change, as all input/output are still block-aligned.

4772005ac1 Give the resamp_do() the exact number input and output samples and

d6bc5ae04f Check that byte order is native only if we're using more than one 
byte per sample, check the samples are lsb-aligned only if there's
padding.
