Add ubus interface to hostapd and wpa_supplicant to allow dynamically
reloading wiface configuration without having to restart the hostapd
process.
As a consequence, both hostapd and wpa_supplicant are now started
persistently on boot for each wifi device in the system and then
receive ubus calls adding, modifying or removing interface
configuration.
At a later stage it would be desirable to reduce the services to one
single instance managing all radios.

b1daf498a tests: Multi-AP WPS provisioning
Add support for Multi-AP to the UCI configuration. Every wifi-iface gets
an option 'multi_ap'. For APs, its value can be 0 (multi-AP support
disabled), 1 (backhaul AP), 2 (fronthaul AP), or 3 (fronthaul + backhaul
AP). For STAs, it can be 0 (not a backhaul STA) or 1 (backhaul STA, can
only associate with backhaul AP).
Also add new optional parameter to wps_start ubus call of
wpa_supplicant to indicate that a Multi-AP backhaul link is required.

similar to hostapd, also add a ubus interface for wpa_supplicant
which will allow handling WPS push-button just as it works for hostapd.
In order to have wpa_supplicant running without any network
configuration (so you can use it to retrieve credentials via WPS),
configure wifi-iface in /etc/config/wireless:
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'wwan'
option mode 'sta'
option encryption 'wps'
This section will automatically be edited if credentials have
successfully been acquired via WPS.
Size difference (mips_24kc): roughly +4kb for the 'full' variants of
wpa_supplicant and wpad which do support WPS.
