Add global wpa_supplicant DUP_NETWORK command

Browse source 
This command allows network variables to be copied from one network to
another when the networks belong to different radios. This is similar to
the per-interface DUP_NETWORK command. On the global control interface,
the command syntax is as follows:

DUP_NETWORK <src ifname> <dst ifname> <src network id> <dst network id> <variable name>
