[libvirt] [PATCH 04/12] Prepare to define proper domain event callback support.

[Claudio Bley]

The old wrapping was of no use since the only thing you could
register was a "generic" callback.

At runtime,you would have to provide a real callback function matching
the prototype of the native callback type.

Trying to use a generic callback instead quickly leads to failure or
JVM crashes.

Thus, it's safe to remove those methods now.
