I've committed the 802.11 simulator

[Adrian Chadd]

Hi,

I've committed monthadar's wifi simulator to -HEAD. The userland tools
aren't there yet but I'll work towards getting those included in the
base system.

It only builds as a module for now - it doesn't have sys/conf/files
entries and the Makefile isn't included in sys/modules/Makefile. I'll
chase these up in subsequent commits.

Monthadar - I had to do a couple of modifications in order to make it
compile on -HEAD with no warnings. Otherwise, it's basically a copy of
'src' in your git tree.

Please send diffs to what's in -HEAD. :-)
