rS323577: Implement gawk multiple-arg extension to and, or, and xor.
rS323576: Bring in bit operation functions, ala gawk.
Summary

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@

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

Minor tab/space issues but otherwise looks fine. Thanks!

There should be TAB instead of space after the #define.

Looks like someone s/0/NULL in the context of a pointer,
so make it look the same.

OK. All the bugs I found are fixed, and the gawk extensions are now implemented more fully. I intend to commit this, unless I hear otherwise.
