[libvirt] [PATCH] fix EventImpl-related error paths in remote driver

This patch makes the remote driver behave properly in the face of: (a) no registered EventImpl, or (b) an EventImpl that returns failure from AddHandle/Timeout In both cases, we now cleanup properly (rather than always passing bogus values to virEventRemoveHandle/Timeout) and fail attempts to register for domain events (w/VIR_ERR_NO_SUPPORT rather than blissfully continue when we can't possibly deliver events).
