[PATCH 0/2] Support the RADIUS server probe

[Gary Ching-Pang Lin <chingpang gmail com>]

wpa_supplicant already provides the function[*] to probe the
certificate of the RADIUS server, and these patches implement the
functions to allow the client of NetworkManager to probe and receive
the certificate for further use.

SHA-256 hash support is also added to nm-settings-8021x as an
alternative of CA certificate file path.
