Add external EAPOL transmission option for testing purposes

Browse source 
The new ext_eapol_frame_io parameter can be used to configure hostapd
and wpa_supplicant to use control interface for receiving and
transmitting EAPOL frames. This makes it easier to implement automated
test cases for protocol testing. This functionality is included only in
CONFIG_TESTING_OPTIONS=y builds.
