If --with-usnic is specified and we can't build the usnic BTL, abort.
If --without-usnic is specified, gracefully skip building the usnic
BTL. If neither is specified, do the OMPI-default behavior: try to
configure/build the usnic BTL, and if we can't, skip it.
Fixes CSCuq13889.

The only user of this code was coll/sm. I implemented a basic replacement
for the removed code. This gets the trunk compiling again with
--disable-dlopen.

common/ofacm is only used by the iboffload code in ompi. This code does
not currently work so it is safe to ignore these components until it is
fixed.

WHAT: Open our low-level communication infrastructure by moving all necessary components (btl/rcache/allocator/mpool) down in OPAL
All the components required for inter-process communications are currently deeply integrated in the OMPI layer. Several groups/institutions have express interest in having a more generic communication infrastructure, without all the OMPI layer dependencies. This communication layer should be made available at a different software level, available to all layers in the Open MPI software stack. As an example, our ORTE layer could replace the current OOB and instead use the BTL directly, gaining access to more reactive network interfaces than TCP. Similarly, external software libraries could take advantage of our highly optimized AM (active message) communication layer for their own purpose. UTK with support from Sandia, developped a version of Open MPI where the entire communication infrastucture has been moved down to OPAL (btl/rcache/allocator/mpool). Most of the moved components have been updated to match the new schema, with few exceptions (mainly BTLs where I have no way of compiling/testing them). Thus, the completion of this RFC is tied to being able to completing this move for all BTLs. For this we need help from the rest of the Open MPI community, especially those supporting some of the BTLs. A non-exhaustive list of BTLs that qualify here is: mx, portals4, scif, udapl, ugni, usnic.

turned out to be a nightmare, as the pointers to the classes are
located in shared libraries memory areas, and are not accesible
after the shared library is unloaded. Thus, OPAL cannot cleanup
the left-over classes from the other shared libraries.

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.

mpirun ... -x env_foo1=val1 -x env_foo2 -x env_foo3=val3 should now be expressed as
mpirun ... -mca mca_base_env_list env_foo1=val1+env_foo2+env_foo3=val3.
The motivation for doing this is so that a list of environment variables may be set via standard MCA mechanisms such as mca parameter files, amca lists, etc.

After discussion with Nathan, change the ERR_VALUE_OUT_OF_BOUNDS to be
ERR_NOT_FOUND, for two reasons:
1. It's consistent with other uses of ERR_NOT_FOUND in the code.
1. In this case, we could have just looked up a variable that is
basically a "hole" -- e.g., var indexes 0, 1, 2 are valid, and 4,
5, and 5 are valid, but 3 is invalid (e.g., 3 was de-registered --
remember that MPI_T explicitly does not allow re-using indexes).
So returning ERR_OUT_OF_BOUNDS seems weird -- returning
ERR_NOT_FOUND seems a bit more natural.
