[Libvir] PATCH: Fix remote driver to handle network API for local non-QEMU

The remote_internal.c code is basically a no-op in its remoteNetworkOpen method. This means the remote driver will only handle the networking APIs, if it is also handling the main domain APIs. This works fine if connecting to a remote URI, or if using QEMU URIs, but it does not work if using the test or Xen drivers. To make this work the remoteNetworkOpen method needs to open a connection to the remote daemon IIF the remoteOpen method did not already open one. So the attached patch adds the neccessary logic in remoteNetworkOpen. It also adds code to remoteNetworkClose to make it shutdown& free the connection IIF it was opened by the remoteNetworkOpen method. This is what the extra 'networkOnly' field in the 'struct private_data' is used to check. Second, all of the implementations of virNetwork* APIs in the remote_internal.c driver must use the 'struct private_data *' from networkPrivateData field in virConnectPtr, not the 'privateData' field. This is because the 'privateData' field is probably storing data related to the Xen or Test drivers. Third, this also fixes the qemu_driver.c which incorrectly used the privateData field insteadof the networkPrivateData field for 2 of the networking APIs, and finally makes sure the qemu_driver.c also acccepts the use of qemu:///session APIs for root user.
