Move the req_mtl structure back to the end of each of the structures in
the CM PML. The req_mtl structure is cast into a mtl_*_request_structure
for each MTL, which is larger than the req_mtl itself. The cast will cause
the *_request to overwrite parts of the heavy requests if the req_mtl
isn't the *LAST* thing on each structure (hence the comment). This was
moved as an optimization at some point, which caused buffer sends to fail...

Add ability for ini files to recognize "use_eager_rdma" flag. Set the
default to "no" (because we should assume that HCAs cannot support the
property necessary for using RDMA for eager messages -- that the last
byte of the message is guaranteed to be written to memory last --
unless proven otherwise. For example, iWARP cards apparently do not
provide this guarantee), and then set all Mellanox and IBM HCAs to
override the default to enable this behavior on these cards.

Also, take the first step in updating how we handle mca params in ORTE - bring it closer to how it is done in the other two layers. Much more work to be done here.
This commit was SVN r12838.
1. no -np provided - put one proc/node across all allocated nodes
2. -np N provided, N > #nodes - we print a pretty error message and exit
3. -np N provided, N <= #nodes - put one proc/node across N nodes
I also added a new orte constant (ORTE_ERR_SILENT) that allows us to pass up the chain that an error was encountered, but NOT print ORTE_ERROR_LOG messages. This is intended to be used for cases where the error we encounter is NOT an orte error, but rather is one associated with incorrect user input (e.g., the preceding case 2). In such cases, there is no point in printing an ORTE_ERROR_LOG chain of messages as it isn't an orte error.

I found only two places that were looking at the tokens:
1. the odls - we used the tokens to separately process the globals container data from everything else. In this case, I left the subscription that returned the globals data alone, but "stripped" the subscription that returned the launch data for the procs. These subscriptions have nothing to do with the xcast message.
2. the pml_base_modex - the callback function was getting process names from the returned tokens. Actually, this function was doing a very bad thing - it was assuming that the first token returned was *always* the process name. This is currently true, but is one of those assumptions that someone could have easily changed - and suddenly found the system inexplicably failing. I modified the function to (a) get the name sent back to us, (b) "stripped" the value structures of tokens and segment strings, and (c) correctly obtained process names from the returned values. I also reindented the heck out of the code so it was legible (at least, to my old eyes).

This commit fixes several aspects regarding MPI conformance of requests.
* Eliminate the last argument of ompi_errhandler_request_invoke(); we
''always'' want to invoke the back-end exception handler with the
real error code.
* Make it clear in comments that we only invoke the ''first''
exception in a given array of requests, even if there's more than
one request with a non-MPI_SUCCESS value for MPI_ERROR.
* Defer the freeing of requests upon exception in the back-end
functions to MPI_WAIT* and MPI_TEST* until later; the requests are
kept so that we know what handler to invoke when we actually invoke
the exception. After figuring that out, ''then'' we free requests
with pending exceptions on them.
* Clean up return codes from the back-end MPI_TEST* and MPI_WAIT*
functions.
* Slightly modify ompi_errcode_get_mpi_code() to return unity if it
receives an MPI error code (vs. an OMPI error code).

usually is ok on little-endian systems, as the upper 32 bits will likely
be ignored, but on 32-bit big-endian systems, lval is complete junk.
Use ival if 32 bit mode, lval if 64.
Mixing of 32 and 64 bit architectures won't work without more changes.
This commit was SVN r12802.
* Do not add new procs to the global list during modex callback or
when sharing orte names during accept/connect. For modex, we
cache the modex info for later, in case that proc ever does get
added to the global proc list. For accept/connect orte name
exchange between the roots, we only need the orte name, so no
need to add a proc structure anyway. The procs will be added
to the global process list during the proc exchange later in
the wireup process
* Rename proc_get_namebuf and proc_get_proclist to proc_pack
and proc_unpack and extend them to include all information
needed to build that proc struct on a remote node (which
includes ORTE name, architecture, and hostname). Change
unpack to call pml_add_procs for the entire list of new
procs at once, rather than one at a time.
* Remove ompi_proc_find_and_add from the public proc
interface and make it a private function. This function
would add a half-created proc to the global proc list, so
making it harder to call is a good thing.
This means that there's only two ways to add new procs into the global proc list at this time: During MPI_INIT via the call to ompi_proc_init, where my job is added to the list and via ompi_proc_unpack using a buffer from a packed proc list sent to us by someone else. Currently, this is enough to implement MPI semantics. We can extend the interface more if we like, but that may require HNP communication to get the remote proc information and I wanted to avoid that if at all possible.
