[Libvir] [PATCH] parse URI once in src/libvirt.c, pass parsed URI to all drivers

The basic change here is that the virDrvOpen call (the internal "open" call for drivers) now takes the parsed xmlURIPtr instead of the raw name string. typedef virDrvOpenStatus (*virDrvOpen) (virConnectPtr conn, - const char *name, + xmlURIPtr uri, int flags); So we avoid the redundant URI parsing which was going on inside all the drivers, and also the ad-hoc "does-it-look-like-a-URI" string comparisons. That's straightforward enough except that all of the drivers were saving the name string in their private data so that they could implement the virConnectGetURI call. I've changed this so that the name is copied and saved in the main virConnect structure, and virConnectGetURI will return that unless the driver wants to override it. You need another patch (coming shortly) to allow URIs like xen://localhost (without the trailing slash) to work, which was IIRC the original point of this discussion.
