Improve LINEAR_LINEARN macro - inparticular BE/LE conversions.
Addresses part of PR kern/52586 analyzed and reported by isaki@.
--
Allow maxused to be an odd number of bytes.  This makes single byte
conversions work for the test described in the PR.
Addresses another part of PR kern/52586.
--
Remove 24 bit in a 32 bit container filters.
At present this filter did not work well and has caused problems with
the audio mixer disabled for hdaudio(4).
These filters may return when they are fixed.
--
Replace LINEARN_TO_LINEARN macro with individual optimized functions for
8, 16, 24 and 32 bits linear to linear conversions.
Addresses PR kern/52586.
--
mulaw/alaw_to_linearN macros replaced with individual faster filters.
