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. Submitted by: Monthadar Al Jaberi <monthadar@gmail.com>
