Well, the virshDomainEventGetName() function doesn't necessarily have to
live in virsh-utils.c. And now that I'm looking into other sources,
maybe this function can be renamed to virshDomainEventToString()? To
match the other functions like virshSecretEventToString() for instance.

We can have virshSecretEventToString(), virshPoolEventToString(), ...
exposed and used in completers.
