DPP: Automatic network profile creation

Browse source 
wpa_supplicant can now be configured to generate a network profile
automatically based on DPP configuration. The following
dpp_config_processing values can be used to specify the behavior:
0 = report received configuration to an external program for
    processing; do not generate any network profile internally (default)
1 = report received configuration to an external program and generate
    a network profile internally, but do not automatically connect
    to the created (disabled) profile; the network profile id is
    reported to external programs
2 = report received configuration to an external program, generate
    a network profile internally, try to connect to the created
    profile automatically
