Jouni Malinen d07d3fbda2 Add peer certificate alt subject name information to EAP events
A new "CTRL-EVENT-EAP-PEER-ALT depth=<i> <alt name>" event is now used
to provide information about server certificate chain alternative
subject names for upper layers, e.g., to make it easier to configure
constraints on the server certificate. For example:
CTRL-EVENT-EAP-PEER-ALT depth=0 DNS:server.example.com

Currently, this includes DNS, EMAIL, and URI components from the
certificates. Similar information is priovided to D-Bus Certification
signal in the new altsubject argument which is a string array of these
items.
