bc98bc9ecb eapol: Add functions to set own/ap WPA IEs

WPA elements are required.

0b48ba3a4a wiphy: Use CMD_DISCONNECT, not CMD_DEAUTHENTICATE 
CMD_DEAUTHENTICATE seems to carry only the management frame pdu
information.  CMD_DISCONNECT is carrying the information that is
actually needed by us:
> Event: Disconnect (0x30) len 28		1140.118545
    Wiphy: 0 (0x00000000)
    Interface Index: 3 (0x00000003)
    Reason Code: 2 (0x0002)
    Disconnect by AP: true

6921e239a4 wiphy: Only support UTF-8 SSIDs 
We will ignore non-UTF8 based SSIDs.  Support for non-UTF8 SSIDs seems
to be of dubious value in the real world as the vast majority of
consumer devices would not even allow such SSIDs to be configured or
used.

There also seems to be no compelling argument to support such SSIDs, so
until that argument arrives, non-UTF8 SSIDs will be filtered out.  This
makes the D-Bus API and implementation much easier.

445ad55796 eapol: Start a handshake timer 
We start a timer.  This handles the case that the Authenticator does
not send us the first message of the 4-way handshake, or disappears
before sending us the 3rd message.

7b945d948f wiphy: Set the linkmode and operstate of the link 
We need to set the linkmode and operstate after successful
authentication.

Initial value for linkmode is 1 (user space controlled) and
IF_OPER_DORMANT for opermode. After successful authentication,
the operstate is set to IF_OPER_UP.

More specific details can be seen in kernel sources at
https://www.kernel.org/doc/Documentation/networking/operstates.txt
