Sebastian Huber f4d541ccfe rtems: Avoid Giant lock in rtems_object_set_name() 
Update #2555.

Sebastian Huber c8982e5f6a posix: Simplify message queues 
The mq_open() function returns a descriptor to a POSIX message queue
object identified by a name.  This is similar to sem_open().  In
contrast to the POSIX semaphore the POSIX message queues use a separate
object for the descriptor.  This extra object is superfluous, since the
object identifier can be used directly for this purpose, just like for
the semaphores.

Sebastian Huber 7e66865e17 score: Move message notification 
Move message notification to end of critical section and delegate the
message queue release to the notification handler.  It may do more
complex notification actions out of the critical section.

Move lock acquire to caller of _CORE_message_queue_Close() to allow
state checks during object close operations under lock protection.
Ensures deletion safety on uni-processor configuration.

Sebastian Huber 9c3bae11b3 rtems: Avoid Giant lock for dual ported memory 
There is no need for an ISR lock since the Dual_ported_memory_Control is
immutable after initialization.  ISR disable is enough for deletion
safety on uni-processor configurations.
