wificfg: add shutdown hooks, and add support to wait until connected.

Browse source 
Remove the wificfg_got_sta_connect() function and replace it with
wificfg_wait_until_sta_connected(). This replaces a probe function with a wait
function, and this better fits the wifi layer using an event model - the wait
function can wait on a station connection event before returning.

The shutdown hooks are call when the wificfg restart function is used. It can
be used to implement a cleaner restart, for example blocking further i2c and
flash operations.
