This patch incorporates a number of bug fixes from the Syslink
2.00.00.12 drop. The following is the summary of changes.

1. sharedregion:
	- sharedregion_remove() is corrected to remove the
		sharedregion entry from the desired processor table.
2. platform_mem:
	- fixed memory leaks.
3. nameserver_remotenotify:
	- an atomic_t variable is added to maintain reference counting
		and the state of the module.
	- nameserver_get_local searches directly copy the value into the
		sharedmemory request buffer.
	- additional error checking is added.
4. messageq:
	- Number of priority queues definition moved from messageq source
		code to messageq header file, and is now also used by
		the messageq_transportshm module.
	- messageqq_transportshm module state object also keeps track of
		the individual messageq_transportshm instances created.
5. listmp_sharedmemory:
	- listmp_sharedmemory_open return value can come from nameserver,
		and so is checked against only a negative value for failure
	- sharedregion value is added into the nameserver database rather
		than the absolute sharedaddr.
	- minor changes in variable names.
6. heapbuf:
	- additional checks were added for valid sharedregion ptrs.
	- heapbuf_open return value can come from nameserver, and so
		is checked against only a negative value for failure.
	- minor changes in variable names.
7. gatepeterson:
	- minor changes in gatepeterson module. This module is currently
		missing the gatespinlock for interrupt context protection.
	- additional checks were added for valid sharedregion ptrs.
