Scheduler: prepare for dropping obsoleted entries

Browse source 
...it is clear that there must be a way to flush the scheduler queues
an thereby silently drop any obsoleted or irrelevant entries. This topic
turns out to be somewhat involved, as it requires to consider the
deadline (due to the memory management, which is based on deadlines).
Furthermore there is a relation to yet another challenging conceptual
requirement, which is the support for other operation modes beyond
just time-bound rendering; these concerns make it desirable to
expand the internal representation of entries in the queue.

Concerns regarding performance are postponed deliberately,
until we can demonstrate the Scheduler-Service running under
regular operational conditions.
