Add backend encryption support for NTLMv2.

The leg-work for this was done by the folks at samba-tng.org, I'm just bringing
it accross to HEAD.

The MD5 implementation is seperatly derived, and does not have the copyright
problems that the one in TNG has.

Also add const to a few places where it makes sence.
