[Libvir] [PATCH] Allow network drivers to decline to take a connection

A couple of problems fixed in the attached patch. Firstly the path used to connect to the network driver in non-root mode was wrong. This may have affected you if you tried to use the test:///default driver as non-root. I haven't tested this fully, but in any case the path is obviously wrong and needs to be fixed. Secondly remote introduces its own network driver, and so we now need to allow network drivers to decline to take a connection (currently they either succeed or give an error - meaning in effect that there can only be one network driver). The first part of the attached patch allows this.
