score: Static Objects_Information initialization

Statically allocate the objects information together with the initial
set of objects either via <rtems/confdefs.h>. Provide default object
informations with zero objects via librtemscpu.a. This greatly
simplifies the workspace size estimate. RTEMS applications which do not
use the unlimited objects option are easier to debug since all objects
reside now in statically allocated objects of the right types.

Close #3621.

87 * The model is to estimate the memory required for each configured item
88 * and sum those estimates.  The estimate can be too high or too low for
89 * a variety of reasons:
90 *
91 * Reasons estimate is too high:
92 *   + FP contexts (not all tasks are FP)
93 *
94 * Reasons estimate is too low:
95 *   + stacks greater than minimum size
96 *   + messages
97 *   + application must account for device driver resources
98 *   + application must account for add-on library resource requirements
99 *
100 * NOTE:  Eventually this may be able to take into account some of
101 *        the above.  This procedure has evolved from just enough to
102 *        support the RTEMS Test Suites into something that can be

643 * @brief Maximum priority configuration.
644 *
645 * This configures the maximum priority value that
646 * a task may have.
647 *
648 * The following applies to the data space requirements
649 * of the Priority Scheduler.
650 *
651 * By reducing the number of priorities in a system,
652 * the amount of RAM required by RTEMS can be significantly
653 * reduced.  RTEMS allocates a Chain_Control structure per
654 * priority and this structure contains 3 pointers.  So
655 * the default is (256 * 12) = 3K on 32-bit architectures.
656 *
657 * This must be one less than a power of 2 between
658 * 4 and 256.  Valid values along with the application
659 * priority levels and memory saved when pointers are
660 * 32-bits in size are:
661 *
662 *   + 3,  2 application priorities, 3024 bytes saved
663 *   + 7, 5 application priorities, 2976 bytes saved
664 *   + 15, 13 application priorities, 2880 bytes saved
665 *   + 31, 29 application priorities, 2688 bytes saved
666 *   + 63, 61 application priorities, 2304 bytes saved
667 *   + 127, 125 application priorities, 1536 bytes saved
668 *   + 255, 253 application priorities, 0 bytes saved
669 *
670 * It is specified in terms of Classic API priority values.
