Noticed this bug while adding qemu monitor events; there's probably
lots of other misuse of libvirt_virDomainPtrWrap, but for now I'm
limiting the fix to all copied-and-pasted event callbacks, since
I'm about to copy it again in the next patch. While at it, check
for failure to extract the "conn" key from the opaque callback
struct, and hoist that check to occur before we reach the point
where it is harder to undo on failure (the network code was the
only code that had it in the right place, but then it failed to
restore thread state on failure).
The graphics callback is still not clean; but incremental
improvements are better than nothing.
