wpa_gui-qt4: Add support for selecting between WEP open/shared key auth

Split the auth=none option into three: open, WEP, WEP with shared key to
allow the user specify WEP with shared key authentication. In addition,
fix static WEP key edits to be enabled only when using static WEP keys
(i.e., not for IEEE 802.1X).

+0.7.x branch:
 - clean up common.[ch]
 - change TLS/crypto library interface to use a structure of function
   pointers and helper inline functions (like driver_ops) instead of
   requiring every TLS wrapper to implement all functions
 - add support for encrypted configuration fields (e.g., password, psk,
   passphrase, pin)
-- wpa_gui: add support for setting and showing priority, auth_alg
-  (open/shared for static WEP)
+- wpa_gui: add support for setting and showing priority
 
 - cleanup TLS/PEAP/TTLS/FAST fragmentation: both the handshake and Appl. Data
   phases should be able to use the same functions for this;
