WPS: Allow PIN timeout to be specified with wpa_supplicant AP/GO

Browse source 
Extend the wpa_cli wps_pin command to support specification of the PIN
expiration time in seconds similarly to hostapd_cli wps_pin command when
using wpa_supplicant for AP mode (including P2P GO).

This starts the WPS negotiation in the same way as above with the
generated PIN.
When the wps_pin command is issued for an AP (including P2P GO) mode
interface, an optional timeout parameter can be used to specify
expiration timeout for the PIN in seconds. For example:
wpa_cli wps_pin any 12345670 300
If a random PIN is needed for a user interface, "wpa_cli wps_pin get"
can be used to generate a new PIN without starting WPS negotiation.
