JunitTest_unoxml_complex crashed with an assertion:

    error: attempt to increment a singular iterator.

This is because the CEventDispatcher::dispatchEvent() attempts to copy the
m_TargetListeners onto the stack, before dropping the mutex to call the,
listeners, but the copy is unintentionally shallow and the ListenerMap
that is the value of the outer type is not copied, so this member is
accessed in callListeners() without MutexGuard.

Fix this by replacing ListenerMap* with ListenerMap as the value,
which also allows getting rid of explicit delete calls.
