[Libvir] [PATCH] Don't throw away errors in virConnectOpen (at least not so often)

Error messages, I like them. I don't like them to be thrown away. A nice feature of virterror is that it'll throw away errors under the following conditions: (1) You are in virConnectOpen, and (2) You pass a non-NULL virConnectPtr to __virRaiseError. libvirt has a lot of errors which meet those conditions - the attached patch fixes the ones I could find. It also fixes qemuOpenConnection so that it doesn't try to open a Unix socket with random stack data. It also adds error messages in some useful places where previously there was an error, but no message.
