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.

also added to explicitly enable or disable SMP. But SMP can only be

i386. With the stub BSP support, a BSP can be run as a single core
SMP system from an RTEMS data structure standpoint.

Refactoring of priority handling, to isolate the bitmap
implementation of priorities in the supercore so that priority
management is a little more modular. This change is in anticipation
of scheduler implementations that can select how they manage tracking
priority levels / finding the highest priority ready task. Note that
most of the changes here are simple renaming, to clarify the use of
the bitmap-based priority management.
