hostapd: Add some testing options

Browse source 
In order to test clients in scenarios where APs may (randomly)
drop certain management frames, introduce some testing options
into the hostapd configuration that can make it ignore certain
frames. For now, these are probe requests, authentication and
(re)association frames.
