Adrian Chadd 04d1980289 Introduce wtap, the beginnings of a net80211 wlan simulator.
This introduces:

* a basic wtap interface
* a HAL, which implements an abstraction layer for implementing
  different device behavious;
* A visibility plugin, which allows for control over which nodes
  see other nodes (useful for mesh work.)

It doesn't yet implement sta/adhoc/hostap modes but these are quite
feasible to implement.

Monthadar uses it to do 802.11s mesh verification.

The userland tools will be committed in a follow-up commit.
