Multiple conduits can exist at the same time, and can even point to the same base transport. Each conduit can have its own characteristics (e.g., flow control) based on the info keys provided to the "open_conduit" call. For ease during the transition period, the "legacy" RML interfaces remain as wrappers over the new conduit-based APIs using a default conduit opened during orte_init - this default conduit is tied to the OOB framework so that current behaviors are preserved. Once the transition has been completed, a one-time cleanup will be done to update all RML calls to the new APIs and the "legacy" interfaces will be deleted.
While we are at it: Remove oob/usock component to eliminate the TMPDIR length problem - get all working, including oob_stress
Instead of ompi_datatype_get_extent(), use ompi_datatype_get_true_extent()
to get the local and remote lower bound. For derived types like
subarray, true_lb is the correct offset for RDMA operations.
Instead of ompi_datatype_get_extent(), use ompi_datatype_get_true_extent()
to get the origin and target lower bound. For derived types like
subarray, true_lb is the correct offset for RDMA operations. Also,
instead of the extent use the size of the datatype.
As long as it is illegal to call MPI_T_init_thread() after MPI_Finalize(),
be gentle and release as much memory as possible in MPI_Finalize().
opal_cleanup() will be invoked again by the OPAL destructor, but will
do nothing since classes was set to NULL
if MPI_Init[_thread]/MPI_Finalize and MPI_T_init_thread/MPI_T_finalize
are balanced, opal_initialized is zero, and hence opal_cleanup destructor
never invokes opal_class_finalize.
if MPI_Init[_thread] nor MPI_T_init_thread have been called, classes is NULL,
so opal_class_finalize does nothing
- replace MAXHOSTNAMELEN with hardcoded 1024.
unlike Linux, Solaris #define MAXHOSTNAMELEN in <netdb.h>,
so use a hard coded value to keep the test simpl
- stdout cannot be assigned on Solaris, so use freopen instead

this is a convenience macro similar to the PMIX_LIST_FOREACH macro,
that can be used to iterate on all the key/value pairs of a pmix_hash_table_t

This commit adds some glue code to support the C++ bindings and
updates the bindings to use the new glue code. This protects our
internal headers (which are C99) from C++. This is done as a quick
workaround to compilation errors when the legacy C++ bindings are
requested.
