When leaving RUN state, release (stop) all used BSS.

rework socket and discovery handling
...
Swtich sockets to connected when talking to a specific AC. Use
unconnected UDP sockets only during DISCOVERY.
In JOIN, we need send our local address. The old, routing table
based local address discovery is broken for many reasons (VRF,
policy routing, ...). With a connected socket, we can the same
information with a simple getsockname.
During DISCOVERY we are talking to all potential AC's at once.
So using an unconnected socket makes still sense.

rework wifi type and rate logic
...
Hard coding basic rates is wrong. Each Wifi types does expect
some default basic rates. However those rates are not set in
stone and the AC is permited to set then to whatever it deems
ok. This might prevent client from connecting, but it still is
the AC decission to do so.
This is first step towards a more flexible basic rate handling.

This has the added benefit that AF_PACKET sockets (e.g. tcpdump)
