Scheduler: Layer-2 complete and tested (see #1326)

Browse source 
* the implementation logic of the Scheduler is essentially complete now
 * all functionality necessary for the worker-function has been demonstrated

As next step, the »Scheduler Service« can be assembled from the two
Implementation Layers, the Activity-Language and the `BlockFlow` allocator
This should then be verified by a multi-threaded integration test...

/** @file scheduler-commutator.hpp
** Layer-2 of the Scheduler: coordination and interaction of activities.
** This is the upper layer of the implementation and provides high-level functionality.
**
** Rendering Activities are represented as a chain of \ref Activity verbs (records),
** which are interconnected to create a low-level _execution language._ The prime
** Activity obviously is to \ref Activity::Verb::INVOKE a \ref JobFunctor encapsulating
** media processing operations; further Activity verbs provide building blocks for
** execution logic, to check preconditions, notify follow-up tasks after calculation
** results are available and to control the scheduling process itself. The Scheduler
** as a service allows to execute Activities while observing time and dependency
** constraints and in response to external events (notably after IO callback).
**
** Activity records are tiny data records (standard layout and trivially constructible);
** they are comprised of a verb tag and a `union` for variant parameter storage, and will
** be managed _elsewhere_ relying on the \ref BlockFlow allocation scheme. Within the
** scheduler queues and execution environment it is thus sufficient to pass `Activity*`.
** While the actual media processing is performed concurrently by a \ref WorkForce with
** a pool of _actively pulling workers,_ any allocations and changes to internal state
** and data structures of the Scheduler itself must be protected against data corruption
** by concurrency. The intended usage scenario involves media data computations which
** are by several orders of magnitude more expensive than all the further internal
** management operations. Thus the design of the Scheduler relies on simple mutual
** exclusion (implemented by atomic lock, see \ref SchedulerCommutator::groomingToken_).
** Each worker in search for the next task will first _acquire_ the Grooming-Token, then
** execute some internal Activities until encountering an actual media computation JobFunctor.
** At this point, the execution will switch from _»grooming mode«_ into _work mode;_ the
** worker _drops_ the Grooming-Token at this point and will then refrain from touching
** any further Scheduler internals. Finally, after completion of the current Render Job,
** the worker will again contend for the Grooming-Token to retrieve more work.
**
** In typical usage, Layer-2 of the Scheduler will perform the following operations
** - accept and enqueue new task descriptions (as chain-of-Activities)
** - retrieve the most urgent entry from Layer-1
** - use the [Activity Language environment](\ref ActivityLang) to _perform_
** the retrieved chain within some worker thread; this is called _dispatch_
** The central cross road of this implementation is the #postDispatch function.
** @see SchedulerCommutator::acquireGroomingToken()
** @see SchedulerCommutator::findWork()
** @see SchedulerCommutator::postDispatch()
