Coverity identified that we treated the possibility that one of the
message buffers could be NULL in some places (because strdup() could
fail), but not in others.
So just use stack buffers that will never be NULL.
This was CID 1269914.
This is a bit of overkill, but I'm cleaning out a bunch of other
libltdl-support assumptions, so I might as well do this one, too. The
test isn't built if we don't have libltdl support, but it had
half-hearted #if protection in it to make it safe to build even if we
didn't have libltdl support. This commit finishes that half-hearted
support.
Squash compiler warnings now showing up in the
query methods for the mtls. Cast pointers to the different
mtl module specific types to the mca_base_module_t.
Also, fix up a missing extern in mtl_psm_types.h.
This was causing "multiple definition" errors when building
the mca_mtl_psm.so shared library.
Switch to using the query/priority method for selecting
MTLs. This switch was motivated by the fact that now
on some platforms, its possible for multiple MTLs to
be initializable, but only one MTL should be selected.
In addition, there is a complication with the PSM and
IFO (with PSM provider) MTLs owing to the fact that
they cannot both intialize the underlying PSM context,
i.e. only one call to psm_init is allowed per process.
The mxm component has not been compiled as the author
doesn't currently have access to a system with a recent
enough mxm installed to allow for a compile.
The portals4, ofi, and psm components have been checked
for compilation. The ofi and psm components have been
checked for runtime correctness on a intel/qlogic system
with up to date PSM installed.
This document is the result of a George Bosilca/Jeff Squyres
discussion at the developer meeting in Dallas in January of 2015. It
attempts to provide some rules of thumb / guidance for naming
conventions of symbols in MPI extensions.

coll ML has two pending issues: a deadlock and a performance critical
on every communicator creation. After confirmation over IM from
Pasha, the ML collective module will be disabled until it is
fixed. Token to Pasha.
