new flag to ompi_info that allows a user to print all MCA variables of a specific type.
--type version_string
This command will print all MCA variables of type version_string.

- -check-shmem-params is OFF by default. It checks OSHMEM API params and will abort on bad input

Adds coll_hcoll_np mca parameter similar to that of fca component (defaults to 32). Those who use hcoll be aware that from now on the communicators less than 32 procs will run w/o hcoll by default. - Resolves fallback issue in case libhcoll runs out of allowed contexts. The solution is moving hcoll_context_create from comm_enable to comm_query. Shortly, comm_enable should never return OMPI_ERROR in the coll component with highest priority (hcoll). Otherwise the ompi coll_base_select will unselect the coll funtion pointers and module references leaving the communicator w/o coll pointer. This will cause the fail. Same behavior can be reproduced even with tuned if one would hardcore some "return OMPI_ERROR" into it's module_enable funtion. - Additionally, removed all the dead code under #if 0; removed unused variables (path for library, active_modules list) and classes (module list wrapper)

- Modifications to coll/hcoll component related to the changes in the libhcoll API.
Now, hcoll_destroy_context accepts one more parameter that indicates if the context was
really destroyed as a result of the call.
This new "non-blocking" context destruction fixes hang discovered in IMB with mcast enabled.
- Clean up all the left contexts (if any) on the comm_world destruction.

1. Change in rte api implementation: now comm_world used to do p2p.
This allows to not worry about other comms being destroyed.
2. added a notification mechanism with a help of which runtime can say libhcoll that RTE api can not be used any longer.
pass a pointer to a flag, and its size to libhcoll.
The flag changes when the RTE is no longer available.
Currently this flag is just ompi_mpi_finalized global bool value.

it can be fixed by its owner.
* It calls AC_MSG_ERROR, which configure.m4 scripts are ''never''
supposed to do. If you don't want to build, then call $2.
* All static and --disable-dlopen builds are broken; they fall afoul
of whatever test configure.m4 is doing and therefore error out of
configure entirely (vs. simply disabling the hcoll component).
* There appear to be multiple shell scripting errors in the
configure.m4. Here's the output of "./configure --disable-dlopen":
{{{
--- MCA component coll:hcoll (m4 configuration macro)
checking for MCA component coll:hcoll compile mode... static
checking --with-hcoll value... simple ok (unspecified)
./configure: line 421: test: basic: integer expression expected
configure: error: Can not use coll/hcoll and coll/ml (static build)
simultaneously. You have two options:
1. Use static build & disable ml with:
--enable-mpi-no-build=coll-ml
2. Use dso build for ML & disable ml at runtime: -mca
coll self
./configure: line 310: return: basic: numeric argument required
./configure: line 320: exit: basic: numeric argument required
}}}
Finally, all of these configure.m4 errors aside, I don't understand
why there is a ''compile-time'' exclusion between the hcoll and ml
components. Why isn't this a ''run-time'' decision? Having what
seems to be an unnecessary compile-time exclusion goes against the
general Open MPI philosophy.
Note: Open MPI 1.7 is also broken in all the same ways. I suggest
that the RM's .ompi_ignore hcoll over there, too.
Mellanox: please fix.

failed. However in this case the returned pointer was set to NULL as well, so the
error code was redundant. Moreover, this was a continuous source of warnings when
the picky mode is on.
The attached parch remove the rc argument from the OMPI_FREE_LIST_GET and
OMPI_FREE_LIST_WAIT macros, and change to check if the item is NULL instead of
using the return code.
