I got your patch off-list, and it's now included in CVS.  I just had to 
un-MSDOS-ify the files and merge new diffs.

It compiles clean, but I haven't actually tried it, but I'm sure people 
on the list will let us know how it works out..

If someone wants to, you can probably make decoding much faster by 
compiling a table at initialization time, and then just doing a table 
lookup at run time, like we do for ulaw.  There's really no downside to 
this, because there are only 256 2-byte entries in the table, so it only 
takes up 512 bytes.  OTOH, for a client, this all doesn't make much 
difference, because we're unlikely to tax anything with encoding or 
decoding.

Encoding is a bit different, because even with the method we use in 
ulaw, there might still be some quantization.  (and a 64K table does 
take more memory, doesn't always fit in cache well, etc).
