pkg{data,lib,includedir}, use our own ompi{data,lib,includedir}, which is
always set to {datadir,libdir,includedir}/openmpi. This will keep us from
having help files in prefix/share/open-rte when building without Open MPI,
but in prefix/share/openmpi when building with Open MPI.

Complements r30073: tighten up the string parsing of the vendor parts
ID MCA param a bit. Also fix a small memory leak: ensure to free the
array uint32_t's parsed out of the MCA param.

This commit adds support for placing the send memory segment in a
traditional shared memory segment when XPMEM is not available. The
current default is to reserve 4MB for shared memory on each process.
The latest benchmarks show vader performing better than sm on both
Intel and AMD CPUs.
For large messages vader will now use CMA if it is available (and
XPMEM is not).

This commit was SVN r30123.
Per RFC which expired two weeks ago:
We are planning to make a change to Open MPI to always set up the btls. This
means the btl init will be called even if add_procs is never called for that
btl. In the openib btl free lists fragments are currently allocated in btl_init.
To avoid wasting that memory this commit moves that final device setup to
the add_procs function. This included allocating free lists, and starting the
async event thread.
At this time this change is safe since we have a barrier after add_procs in
MPI_Init. If this changes we will need to re-think some of the initialization
since we might have the possibility of a connection request before add_procs
is called.
Tested with Mellanox ConnectX2 and QLogic HCAs.
Commit also cleans up tabs in btl_openib_async.c.

1. Fix ompi_info memory leak in usnic BTL: do not allocate memory in
the component register function, because ompi_info only calls the
component register function and then dlclose's the component -- it
does not call component finalize. Instead, defer parsing the MCA
param (and alloc'ing memory) until the component init function so
that any allocated memory can be freed in the component close
function.
1. Also add a new check to ensure that we actually have some part
numbers to check. Add a show_help message if we don't find any
vendor part IDs to check.
1. Add a verbose output if usnic disqualifies itself from selection
because THREAD_MULTIPLE was specified.

- 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.

This patch changes all send/send_buffer occurrences in the C/R code
to send_nb/send_buffer_nb.
The new code compiles but does not work.
Changes from V1:
* #ifdef out the code (so it is preserved for later re-design)
* marked the broken C/R code with ENABLE_FT_FIXED
Changes from V2:
* just replace the blocking calls with the non-blocking calls
* all #ifdef's introduced in V1 are gone
* send_* returns error code or ORTE_SUCCESS (not the number of bytes)
This commit was SVN r30036.
This patch changes all recv/recv_buffer occurrences in the C/R code
to recv_nb/recv_buffer_nb.
The old code is still there but disabled using ifdefs (ENABLE_FT_FIXED).
The new code compiles but does not work.
Changes from V1:
* #ifdef out the code (so it is preserved for later re-design)
* marked the broken C/R code with ENABLE_FT_FIXED
Changes from V2:
* only #ifdef out the code where the behaviour is changed
(used to be blocking; now non-blocking)

Fix comm_spawn on a single host - with the new default mapping scheme, we were incorrectly computing the number of procs to put on the node.
