mac80211: make bridge_packets a virtual interface option

Browse Source 
The bridge_packets configuration really should be per virtual
interface (theoretically per AP/VLAN, but this is much easier);
there currently is no way to set it yet though. Also invert
the option to "NO_BRIDGE_PACKETS" so the default is to bridge.

While at it, also document the flags properly.
