score: Rename interrupt stack symbols

Rename

  • _Configuration_Interrupt_stack_area_begin in _ISR_Stack_area_begin,
  • _Configuration_Interrupt_stack_area_end in _ISR_Stack_area_end, and
  • _Configuration_Interrupt_stack_size in _ISR_Stack_size.

Move definitions to <rtems/score/isr.h>. The new names are considerable
shorter and in the right namespace.

Update #3459.

  • Property mode set to 100644

73 * This module contains all RTEMS Configuration parameters.
74 *
75 * The model is to estimate the memory required for each configured item
76 * and sum those estimates.  The estimate can be too high or too low for
77 * a variety of reasons:
78 *
79 * Reasons estimate is too high:
80 *   + FP contexts (not all tasks are FP)
81 *
82 * Reasons estimate is too low:
83 *   + stacks greater than minimum size
84 *   + messages
85 *   + application must account for device driver resources
86 *   + application must account for add-on library resource requirements
87 *
88 * NOTE:  Eventually this may be able to take into account some of
89 *        the above.  This procedure has evolved from just enough to
90 *        support the RTEMS Test Suites into something that can be
91 *        used remarkably reliably by most applications.

631 * @brief Maximum priority configuration.
632 *
633 * This configures the maximum priority value that
634 * a task may have.
635 *
636 * The following applies to the data space requirements
637 * of the Priority Scheduler.
638 *
639 * By reducing the number of priorities in a system,
640 * the amount of RAM required by RTEMS can be significantly
641 * reduced.  RTEMS allocates a Chain_Control structure per
642 * priority and this structure contains 3 pointers.  So
643 * the default is (256 * 12) = 3K on 32-bit architectures.
644 *
645 * This must be one less than a power of 2 between
646 * 4 and 256.  Valid values along with the application
647 * priority levels and memory saved when pointers are
648 * 32-bits in size are:
649 *
650 *   + 3,  2 application priorities, 3024 bytes saved
651 *   + 7, 5 application priorities, 2976 bytes saved
652 *   + 15, 13 application priorities, 2880 bytes saved
653 *   + 31, 29 application priorities, 2688 bytes saved
654 *   + 63, 61 application priorities, 2304 bytes saved
655 *   + 127, 125 application priorities, 1536 bytes saved
656 *   + 255, 253 application priorities, 0 bytes saved
657 *
658 * It is specified in terms of Classic API priority values.
