* DESCRIPTION:
*
* Mix 3 32-bit values reversibly. For every delta with one or two
* bits set, and the deltas of all three high bits or all three low
* bits, whether the original value of a,b,c is almost all zero or is
* uniformly distributed.
*
* If HASH_MIX() is run forward or backward, at least 32 bits in a,b,c
* have at least 1/4 probability of changing. If mix() is run
* forward, every bit of c will change between 1/3 and 2/3 of the
* time. (Well, 22/100 and 78/100 for some 2-bit deltas.)
*
* HASH_MIX() takes 36 machine instructions, but only 18 cycles on a
* superscalar machine (like a Pentium or a Sparc). No faster mixer
* seems to work, that's the result of my brute-force search. There
* were about 2^68 hashes to choose from. I only tested about a
* billion of those.

* expand_chars
*
* DESCRIPTION:
*
* Copies a buffer into a output buffer while translates
* non-printables into %03o octal values. If it can, it will also
* translate certain \ characters (\r, \n, etc.) into \\%c. The
* routine is useful for printing out binary values.
*
* NOTE: It does _not_ add a \0 at the end of the output buffer.
*
* RETURNS:
*
* Returns the number of characters added to the output buffer.
*
* ARGUMENTS:
*
* buf - the buffer to convert.
*
* buf_size - size of the buffer. If < 0 then it will expand till it
* sees a \0 character.
*
* out - destination buffer for the convertion.
*
* out_size - size of the output buffer.
