bf868c4a9b tiny_psnr: fix range calculation for sample size of 32 bits 
For a sample size of 32 bits, the shift would overflow producing
undefined results.  Incidentally, in the only test currently using
32-bit samples, the output matches the reference exactly on most
systems meaning the bad 'max' value is never used.

3dc06b6972 tiny_psnr: check for specified sample size less than 1 
A zero or negative sample size is impossible and should be
reported as an error.

c43d77c163 tiny_psnr: skip wav headers on input files 
The byte count printed excludes the header, and offsets are applied
after the the headers are skipped.

Reference files updated to reflect new output.  Some stddev/psnr values
have changed slightly due to headers no longer being compared.

1e90317b65 Fix tiny_psnr so it compares all bytes (it did skip the last block). 
Also display both file sizes and slightly change the output formatting.
[not split in 3 patches to avoid the huge checksum files from being changed
 and having to be reviewed 3 times, if people want it split i can revert and
 split it]
