hostapd: add support for wifi-station and wifi-vlan sections

This patch adds support for 2 new uci sections.

config wifi-vlan
	# iface is optional. if it is not defined the vlan will apply
	# to all interfaces
        option iface	default_radio0
        option name	guest
        option vid	100
        option network	guest

config wifi-station
	# iface is optional. if it is not defined the station will apply
	# to all interfaces
        option iface	default_radio0
        # mac is optional. if it is not defined it will be a catch all
	# for any sta using this key
	option mac	'00:11:22:33:44:55'
        # vid is optional. if it is not defined, the sta will be part of
	# the primary iface.
	option vid	100
        option key	testtest

With this patch applied it is possible to use multiple PSKs on a single BSS.
