In the Red-Black Tree Heap the administration data structures are not
contained in the managed memory area. This can be used for example in a
task stack allocator which protects the task stacks from access by other
tasks.

rtems_configuration_table.

score/Makefile.am, score/preinstall.am: Add the CBS (Constant
Bandwidth Server) scheduler. This is a complex scheduling policy
built atop of the EDF scheduler. Unlike other schedulers, this one
provides a user API and handles not only deadlines of tasks but also
claimed budget per period. The main aim of the scheduler is isolation
of tasks so that each task is guaranteed to meet all deadlines
regardless of how other tasks behave.

This was heavy handed since you can only use one scheduler

scheduler pointer being passed around when you could put all
scheduler configuration in an initialized structure.
