In sysmgr_ioctl, the execution of CMD_SYSMGR_STOPCALLBACK does not set the
return value in cargs.api_status.  This caused an error sometimes because the
status was uninitialized.  Now it sets the status to 0 just like for the cases
of CMD_SYSMGR_LOADCALLBACK and CMD_SYSMGR_STARTCALLBACK.  Note that since the
platform callbacks return void, we must set the api_status manually.

In proc4430, ducati_destroy() is called from both proc4430_destroy() and
proc4430_stop().  Since ducati_setup() is called from proc4430_start(), the
call to ducati_destroy() in proc4430_destroy() is invalid.  It generates a
crash.

Failed statements are printed in the IPC module xxx_destroy() functions
only after checking if the status value indicates an error condition. This
is to avoid confusion by the existing trace statement word 'failed'. This
statement was being printed if the xxx_destroy jumps to exit label because
the module's reference count is not yet zero.

platform_stop_callback now reads the config info for each module, just like
platform_start_callback does.  The problem was that it didn't read it before,
nor did it save the config info from platform_start_callback for each Ducati
core separately.  Thus only the AppM3 config was saved, and then used for SysM3
cleanup.

When a heapbuf object is created, there are two memory buffers allocated -- one
for the handle and one for the object itself.  That is in _heapbuf_create.  In
heapbuf_delete, both are freed.  But in heapbuf_close, only the handle is freed.
The object pointer is not freed and caused a memory leak.  This patch adds a
call to free the object.

In the function notify_ducatidrv_unregister_event, it finds the event listener

sysmgr_destroy was not cleaning up platform_mem.  As a result, memory allocated

handle.  It now frees it correctly.

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.
