5715281918 gp: Implement appliers for monitoring policy changes
This is currently a significant drawback of Samba
Group Policy. CSEs MUST be aware of policy changes
such as modification, removal, etc. This is a
complex process, and is easy to mess up. Here I
add 'appliers' (the first being for files), which
handle the complexty transparently to ensure this
is done correctly.

Compression uses a 3 byte hash remember LZ77 matches in a 14-bit table.
This script runs the hash over all 16M combinations, then again over
all ASCII combinations, counting collisions to find hot-spots.

If you think you have a better hash, you are probably right, but you
should try it here -- alter h() -- before committing to it. This one is
literally the first one I thought of.
