score: Multiprocessor Resource Sharing Protocol

Add basic support for the Multiprocessor Resource Sharing Protocol
(MrsP).

The Multiprocessor Resource Sharing Protocol (MrsP) is defined in A.
Burns and A.J. Wellings, A Schedulability Compatible Multiprocessor
Resource Sharing Protocol - MrsP, Proceedings of the 25th Euromicro
Conference on Real-Time Systems (ECRTS 2013), July 2013. It is a
generalization of the Priority Ceiling Protocol to SMP systems. Each
MrsP semaphore uses a ceiling priority per scheduler instance. These
ceiling priorities can be specified with rtems_semaphore_set_priority().
A task obtaining or owning a MrsP semaphore will execute with the
ceiling priority for its scheduler instance as specified by the MrsP
semaphore object. Tasks waiting to get ownership of a MrsP semaphore
will not relinquish the processor voluntarily. In case the owner of a
MrsP semaphore gets preempted it can ask all tasks waiting for this
semaphore to help out and temporarily borrow the right to execute on one
of their assigned processors.

The help out feature is not implemented with this patch.

4	* @brief Configuration Table Template that will be Instantiated
5	* by an Application
6	*
7	* This include file contains the configuration table template that will
8	* be instantiated by an application based on the setting of a number
9	* of macros. The macros are documented in the Configuring a System
10	* chapter of the Classic API User's Guide
11	*
12	* The model is to estimate the memory required for each configured item
13	* and sum those estimates. The estimate can be too high or too low for
14	* a variety of reasons:
15	*
16	* Reasons estimate is too high:
17	* + FP contexts (not all tasks are FP)
18	*
19	* Reasons estimate is too low:
20	* + stacks greater than minimum size
21	* + messages
22	* + application must account for device driver resources
23	* + application must account for add-on library resource requirements
24	*
25	* NOTE: Eventually this may be able to take into account some of
26	* the above. This procedure has evolved from just enough to
27	* support the RTEMS Test Suites into something that can be
28	* used remarkably reliably by most applications.

629	*
630	* By reducing the number of priorities in a system,
631	* the amount of RAM required by RTEMS can be significantly
632	* reduced. RTEMS allocates a Chain_Control structure per
633	* priority and this structure contains 3 pointers. So
634	* the default is (256 * 12) = 3K on 32-bit architectures.
635	*
636	* This must be one less than a power of 2 between
637	* 4 and 256. Valid values along with the application
638	* priority levels and memory saved when pointers are
639	* 32-bits in size are:
640	*
641	* + 3, 2 application priorities, 3024 bytes saved
642	* + 7, 5 application priorities, 2976 bytes saved
643	* + 15, 13 application priorities, 2880 bytes saved
644	* + 31, 29 application priorities, 2688 bytes saved
645	* + 63, 61 application priorities, 2304 bytes saved
646	* + 127, 125 application priorities, 1536 bytes saved
647	* + 255, 253 application priorities, 0 bytes saved
