Request for updated bit manipulation library

[Mak Kolybabi <mak () kolybabi com>]

I have a need for the ability to perform bitwise operations on 64-bit integers.
I have been struggling with strange behaviour with the current bit library when
the numbers get too large. The website Nmap's bit library originally came from
has a new version, and its changes mention that there were issues with shifting
previously. Any chance someone would be kind enough to integrate the newer
version of the library into Nmap?

The odd behaviour is as follows (script attached):

NSE: Starting bit-test against 127.0.0.1.
NSE: 0000000000000000 = 0000000000000000 << 8
NSE: 00000000000000ff = 0000000000000000 or 0xFF
NSE: 000000000000ff00 = 00000000000000ff << 8
