Jouni Malinen 200c7693c9 Make WEP functionality an optional build parameter 
WEP should not be used for anything anymore. As a step towards removing
it completely, move all WEP related functionality to be within
CONFIG_WEP blocks. This will be included in builds only if CONFIG_WEP=y
is explicitly set in build configuration.
