5b7943db78 ompi/group: do not allocate ompi_proc_t's on group union/difference
This commit modifies the ompi_group_t union/difference code to compare/copy the
raw group values. This will either be a ompi_proc_t or a sentinel value. This
commit also adds helper functions to convert between opal process names and
sentinel values.

10cf64373a osc-portals4: allow atomic ops on datatypes that are max_fetch_atomic_size bytes in length
Portals4 supports atomic ops on datatypes less than or equal to
max_fetch_atomic_size bytes.  This commit fixes a bug that required
the datatype to be less than max_fetch_atomic_size bytes.

9df163f116 portals4: use a single Memory Descriptor to cover all of memory
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.

5f1254d710 Update code base to use the new opal_free_list_t
Use of the old ompi_free_list_t and ompi_free_list_item_t is
deprecated. These classes will be removed in a future commit.

This commit updates the entire code base to use opal_free_list_t and
opal_free_list_item_t.

Notes:

OMPI_FREE_LIST_*_MT -> opal_free_list_* (uses opal_using_threads ())

bf89131f9e add owner files to opa/ompi/orte mca directories
This commit adds an owner file in each of the component directories
for each framework.  This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page.  Currently there are two
"fields" in the file, an owner and a status.  A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.

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.

42a871efd4 This commit fixes trac:4662 - "Portals4/MTL hangs in c_get_accumulate test".
- Portals4/OSC was unable to acquire an exclusive lock due to an invalid
local address in the atomic operation.  This caused the reported hang.
- After fixing the hang, the test continued to fail because
ompi_datatype_is_contiguous_memory_layout() reports that MPI_EMPTY (the
origin datatype) is noncontiguous and Portals4/OSC does not support
noncontiguous datatypes at this time.  However, in this case the origin
count is zero so contiguous/noncontiguous is irrelevant.  Now we skip
the contiguous check if the count is zero.

d5d2d5c4d8 Add an internal ompi error code for RMA sync errors.
Dave Goodell correctly pointed out that it is unusual to return MPI
error classes from internal ompi functions. Correct this in the RMA
case by adding an internal error code to match MPI_ERR_RMA_SYNC.

This does change OMPI_ERR_MAX. I don't think this will cause any
problems with ABI.
