…der events If OMPI is initialized as thread multiple, then it is possible for Portals events to be processed out of order by different threads. Out of order events could lead to reactivation of the block (PTL_EVENT_AUTO_FREE) before the block is removed from the active list (PTL_EVENT_AUTO_UNLINK). This commit adds a status field to ompi_mtl_portals4_recv_short_block_t that coordinates these events.

…der events
If OMPI is initialized as thread multiple, then it is possible for
Portals events to be processed out of order by different threads.
Out of order events could lead to reactivation of the block
(PTL_EVENT_AUTO_FREE) before the block is removed from the active
list (PTL_EVENT_AUTO_UNLINK). This commit adds a status field to
ompi_mtl_portals4_recv_short_block_t that coordinates these events.
If OMPI is built without support for thread multiple, then the coordination
code is compiled out so we maintain our current single threaded
performance.
