PR 582/core * src/mqueue.c, src/mqueuecreatesupp.c, src/mqueuedeletesupp.c, src/mqueueunlink.c: Use memory from workspace to avoid use of mutex during dispatch disable critical section. Besides memory for object names should come from the Workspace anyway.

* NOTE: The structure of the routines is identical to that of POSIX
|
|
* Message_queues to leave the option of having unnamed message
|
|
* queues at a future date. They are currently not part of the
|
|
* POSIX standard but unnamed message_queues are. This is also
|
|
* the reason for the apparently unnecessary tracking of
|
|
* the process_shared attribute. [In addition to the fact that
|
|
* it would be trivial to add pshared to the mq_attr structure
|
|
* and have process private message queues.]
|
|
*
|
|
* This code ignores the O_RDONLY/O_WRONLY/O_RDWR flag at open
|
|
* time.
