e1389f3983 event-test: Get rid of useless and ambiguous VIR_DEBUG macro
The event test does not try to include libvirt internals. Using a macro
named VIR_DEBUG might hint to such usage. Additionally it's useless
since it's used only in the main() function.

Modernize the message strings while touching them.

cbe289d814 event-test: Check for virConnectRegisterCloseCallback return value
In an unlikely event of virConnectRegisterCloseCallback failing,
the error is ignored. This is an example file and we shouldn't
get a bad example.

bde75a895d event-test: Use goto cleanup instead of if else jungle
Like in the rest of our code we tend to prefer 'goto' and

5a9cbc6265 Add event and state details for post-copy
VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY and VIR_DOMAIN_PAUSED_POSTCOPY are
used on the source host once migration enters post-copy mode (which
means the domain gets paused on the source. After the destination host
takes over the execution of the domain, its virtual CPUs are resumed and
the domain enters VIR_DOMAIN_RUNNING_POSTCOPY state and
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event is emitted.

In case migration fails during post-copy mode and none of the hosts have
complete state of the domain, both domains will remain paused with
VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason and an upper layer may decide
what to do.

f7fee15ae8 event-test: Unregister close callback
When registering a close callback, the connection refcount is increased
as the connection object is passed to the callback and hence we must
prevent deleting it too soon. However, when closing the connection, the
connection object is just unrefed. So whenever a connection with a close
callback is closed, we end up with the connection object which has
exactly one reference. Leaving the code as-is doesn't mean the end of
the world as we know it, but why give a bad example?
