[RFC 0/4] wpa_supplicant: remote access for ctrl_iface

[Janusz.Dziedzic at tieto.com]

Added new option that will enable remote access
to wpa_supplicant ctrl iface.
This should be used only for test purpose
because lack of authentication, but could
be very usefull for tests tools that could
configure wpa_supplicants remotly now.

This flag will enable feature:
CONFIG_CTRL_IFACE=udp-remote

Added changes to wpa_supplicant and also to
wpa_cli. Wpa_cli could be used now as a client:

eg.
wpa_cli -i <hostname>:[port]
wpa_cli -i <IP>:[port]

Also change ports range to allow multiple 
wpa_supplicant instances and multiple VIFs.

Added also user friendly prompt to wpa_cli
when this feature is used, to be sure which
interface/host is used.

eg.
localhost/wlan0>
192.168.1.1/p2p-wlan-0-0>



I am using this during manual tests when manage
all PCs (supplicants) from one machine using
ethernet connection.

Please check and comment.
