First cut at client side configuration of wireless nodes. Redhat only,
no freebsd support. The primary change is that tmcd now sends down a list of setting to apply to each interface, and that list is turned into a hash table, and provided to rc.config, which passes them along to the machine dependent routine in liblocsetup. Then in the linux version of liblocsetup there is a bunch of new code to configure wireless links using iwconfig and iwpriv, using the settings array. All of this is bound to change once we get more experience with it.
