* Move ipv6comat.h code into opal_config_bottom.h and change into some
more intelligent testing of structures
* Change opal's if interface to use sockaddr instead of sockaddr_storage,
as the RFCs suggest we do
* Move the networking code in opal that isn't directly related to if
detection into net.h
* Add quicky function to get the port out of either a sockaddr_in
or sockaddr_in6, saving a bunch of code in the oob.
* Update TCP oob and btl with new interface
