config: Simplify clustered scheduler configuration

Do not use names derived from scheduler implementation details. Instead
use names derived from the scheduler configuration or documentation.

Provide defines for backward compatibility.

66 * This module contains all RTEMS Configuration parameters.
67 *
68 * The model is to estimate the memory required for each configured item
69 * and sum those estimates.  The estimate can be too high or too low for
70 * a variety of reasons:
71 *
72 * Reasons estimate is too high:
73 *   + FP contexts (not all tasks are FP)
74 *
75 * Reasons estimate is too low:
76 *   + stacks greater than minimum size
77 *   + messages
78 *   + application must account for device driver resources
79 *   + application must account for add-on library resource requirements
80 *
81 * NOTE:  Eventually this may be able to take into account some of
82 *        the above.  This procedure has evolved from just enough to
83 *        support the RTEMS Test Suites into something that can be
84 *        used remarkably reliably by most applications.

650 * @brief Maximum priority configuration.
651 *
652 * This configures the maximum priority value that
653 * a task may have.
654 *
655 * The following applies to the data space requirements
656 * of the Priority Scheduler.
657 *
658 * By reducing the number of priorities in a system,
659 * the amount of RAM required by RTEMS can be significantly
660 * reduced.  RTEMS allocates a Chain_Control structure per
661 * priority and this structure contains 3 pointers.  So
662 * the default is (256 * 12) = 3K on 32-bit architectures.
663 *
664 * This must be one less than a power of 2 between
665 * 4 and 256.  Valid values along with the application
666 * priority levels and memory saved when pointers are
667 * 32-bits in size are:
668 *
669 *   + 3,  2 application priorities, 3024 bytes saved
670 *   + 7, 5 application priorities, 2976 bytes saved
671 *   + 15, 13 application priorities, 2880 bytes saved
672 *   + 31, 29 application priorities, 2688 bytes saved
673 *   + 63, 61 application priorities, 2304 bytes saved
674 *   + 127, 125 application priorities, 1536 bytes saved
675 *   + 255, 253 application priorities, 0 bytes saved
676 *
677 * It is specified in terms of Classic API priority values.
