Bring in bit operation functions, ala gawk.

These are from OpenBSD:
>>> Extend awk with bitwise operations. This is an extension to the awk
>>> spec and documented as such, but comes in handy from time to time.
>>> The prototypes make it compatible with a similar GNU awk extension.
>>>
>>> ok millert@, enthusiasm from deraadt@

Edited to fix cut and paste in error messages, as well as
using tabs instead of spaces after #defines added.

Obtained From: OpenBSD awk.h 1.12, lex.c 1.10, run.c 1.29
