The callers in the monitor code invoking the callbacks after events are
received don't actually check the return value from the callbacks and
there isn't really anything we could do on failure.
Remove the return value from the intermediary functions so we can later
remove them from the callback prototypes.

When doing a peer-to-peer migration it may happen that the
connection to the destination disappears. If that happens,
there's no point in trying to unregister the close callback
because the connection is closed already. It results only in
polluting logs with this message:
error : virNetSocketReadWire:1814 : End of file while reading data: : Input/output error
and the reason for that is unregistering a connection callback
results in RPC (among other things).

The code is correct, and this only happens when building at -O2.
The docs for -Warray-bounds say that a value of "2" is known to
be liable to generate false positives. Rather than downgrade the
check everywhere, we do it selectively for sanitizers.

Signaling the condition before vm->def->id is reset to -1 is dangerous:
in case a waiting thread wakes up, it does not see anything interesting
(the domain is still marked as running) and just enters virDomainObjWait
where it waits forever because the condition will never be signalled
again.
Originally it was impossible to get into such situation because the vm
object was locked all the time between signaling the condition and
resetting vm->def->id, but after commit 860a999802 released in 6.8.0,
qemuDomainObjStopWorker called in qemuProcessStop between
virDomainObjBroadcast and setting vm->def->id to -1 unlocks the vm
object giving other threads a chance to wake up and possibly hang.
In real world, this can be easily reproduced by killing, destroying, or
just shutting down (from the guest OS) a domain while it is being
migrated somewhere else. The migration job would never finish.
So let's make sure we delay signaling the domain condition to the point
when a woken up thread can detect the domain is not active anymore.
