from the message queues (a debugging feature). With this approach
all blocking (single threaded) requests are allocated from the main
freelist, so they will be accounted for during the message queues
investigation).
The Portals4 MTL allocates two Portals IDs requesting specific
well-known IDs and assumes that those IDs are allocated. If those IDs
are in use, PtlPTAlloc() will allocate a different ID. This commit
verifies that the requested IDs were allocated.
CID 1295340 Unchecked return value (CHECKED_RETURN)
Check the return code of mca_base_framework_open. If the call fails for some reason
the component array will not be properly defined. This will cause issues in
mca_topo_base_find_available.

CID 70630 Dereference before null check
Cleaned up useless goto statements and deleted NULL check. If
mca_base_select returns success than best_module and best_component
will always be non-NULL.

When activating short receive blocks on the overflow list, remove
the PTL_ME_EVENT_LINK_DISABLE flag so the event gets generated.
Without PTL_EVENT_LINK, the block status can't reach the activated
state.
Replace #ifdef with #if for Open MPI configure booleans, because
Open MPI configure booleans are always defined and the value must
be checked.
In days past, some implementations of Portals4 could not cover all
of memory with a single Memory Descriptor so multiple large
overlapping Memory Descriptors were created. Because none of the
current implementations have this limitation (and no future
implementations should either), this commit removes the overlapping
Memory Descriptors code.
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.
Rename all files and symbols from "io_romio" to "io_romio314". This
fixes --disable-dlopen builds (because they were missing
the mca_io_romio314_component symbol).
Per the MPI 3.0 standard (chapter 7, page 310) :
"If maxindegree or maxoutdegree is smaller than the numbers returned by
MPI_DIST_GRAPH_NEIGHBOR_COUNT, then only the first part of the full list is returned."
