Andrew Friedley cf9246f7b9 Long overdue commit.. many changes.
In short, I'm very close to having connection establishment and eager send/recv working.

Part of the connection process involves sending address information from the
client to server.  For some reason, I am never receiving an event indicating
completetion of the send on the client side.  Otherwise, connection
establishment is working and eager send/recv should be trivial from here.


Some more detailed changes:
 - Send partially implemented, just handles starting up new connections.
 - Several support functions implemented for establishing connection.  Client
   side code went in btl_udapl_endpoint.c, server side in btl_udapl_component.c
 - Frags list and send/recv locks added to the endpoint structure.
 - BTL sets up a public service point, which listens for new connections.
   Steps over ports that are already bound, iterating through a range of ports.
 - Remove any traces of recv frags, don't think I need them after all.
 - Pieces of component_progress() implemented for connection establishment.
 - Frags have two new types for connection establishment - CONN_SEND and
   CONN_RECV.
 - Many other minor cleanups not affecting functionality
