Review request for qpid, Gordon Sim, Justin Ross, and Robbie Gemmell.

Bugs: PROTON-1133

Repository: qpid-proton-git

Description (updated)

This involves a change to the Reactor API.

This patch implements a new API for creating outgoing connections via the Reactor class: pn_reactor_connection_to_url().
 It is meant to replace the existing practice of creating a connection via pn_reactor_connection()
then setting the transport address in the connection's hostname field.

Not 100% convinced this is appropriate.  It introduces a URL parameter to the Proton Connection
object, where it may make better sense to associate the URL with the Transport instead (pn_reactor_transport_to_url()???).

The URL parameter is used by the Proton iohandler to create the socket connection.  If an
application does not use the Proton iohandler (by overriding the reactor's global handler),
then it is the responsiblity of whatever handler is being provided to use the URL to set up
the socket connection.  This was also the case for the old method that used the connection's
hostname setting, so this is not a behavioral change.
