This all looks pretty good to me. The only thing I'm not really liking
is the VIR_EVENT_NAMESPACE stuff exposed in the public header. Since we
have separate public APIs for registering event callbacks for each type
of object, there is no need to have namespaces for event IDs from an
app developers POV. I understand you want to encode things into a single
event ID space internally for ease of handling, but I think we should
not expose this to apps.

The internal code alwas has VIR_ENUM_SENTINELS defined so can rely
on using any _LAST constant. We simply hide from the client applications
by default.
