Add two new configure options that specify:
1. when to add padding to the openib control header - this *only* happens when the configure option is specified
2. when to use the dr-like checksum as opposed to the memcpy checksum. Not selectable at runtime - to eliminate performance impacts, this is a configure-only option
Also removed an unused checksum version from opal/util/crc.h.
The new component still needs a little cleanup and some sync with recent ob1 bug fixes. It was created as a separate module to avoid performance hits in ob1 itself, though most of the code is duplicative. The component is only selectable by either specifying it directly, or configuring with the dr-like checksum -and- setting -mca pml_csum_enable_checksum 1.
Modify the LANL platform files to take advantage of the new module.

Now, while #include "ompi_config.h" is good and fine in order
to have OMPI_DECLSPEC,
here it led to stdint.h (with the uint8_t) being included early
but INSIDE a namespace "MPI" {}.
Of course it was included anymore (thinkg #define _STDINT_H), when
it was required in opal/class/opal_hash_list.h
NOT good.

Added a few comments and changed the return code after the FIFO write to be SUCCESS,
even if the FIFO write indicated an error. Such an error would only mean that the
FIFO was full, but the FIFO-write operation would still be queued. Therefore, the
PML should think of this as successful.

devel list, it ''is'' within in the spirit of MPI to allow
MPI_REQUEST_NULL to be passed to MPI_REQUEST_GET_STATUS. I filed a
ticket proposal with MPI-2.2 to make this officially accepted:
https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/137
Plus, r20537 didn't revert out all of the machinery for allowing
MPI_REQUEST_NULL or inactive requests, anyway. So this commit simply
removes the parameter check that was added in r20537, and we're back
to where we were before this whole conversation. :-)

deactivated by default. It is activated by setting either of the
following two MCA parameters to values greater than 0:
* coll_sync_barrier_before
* coll_sync_barrier_after
If !_before is >0, then the sync coll collective will insert itself
before the underlying collective operations and invoke a barrier
before every Nth barrier (N == coll_sync_barrier_before). Similar for
!_after. Note that N is a _per communicator_ value; not global to the
MPI process.
If both are 0 (which is the default), this component returns NULL for
the comm query, meaning that it is not insertted into the coll module
stack.
The intent of this component is to provide a a workaround for
applications with large numbers of collectives of short messages that
can cause unbounded unexpected messages. Specifically, it is possible
for some iterative collective communication patterns to cause
unbounded unexpected messages. Forcing a barrier before or after
every Nth collective operation would prevent that behavior by forcing
applications to synchronize (and thereby consume any outstanding
unexpected messages caused by collectives on the same communicator).
Open MPI still needs to bound unexpected messages resource consumption
at the receiver, but this is a viable workaround for at least some
symptoms of the problem.
Additionally, there has been anecdotal evidence of some applications
that "perfom better" when they put barriers after other collective
operations. This could be due to many factors -- including shortening
the unexpected message queue. Putting this component in Open MPI
allows people to try this with their own applications and give real
world feedback on this kind of behavior.

* The main thing done here is to convert from multiple FIFOs/queues per
receiver (each receiver has one FIFO for each sender) to a single FIFO/queue
per receiver (all senders sharing the same FIFO for a given receiver).
* This requires rewriting the FIFO support, so that
ompi/class/ompi_[circular_buffer_]fifo.h is no longer used and FIFO
support is instead in btl_sm.h.
* The number of FIFOs per receiver is actually an MCA tunable parameter,
but it appears that 1 or possibly 2 FIFOs (even for 112 local processes)
per receiver is sufficient.

The prior ompi_proc_t structure had a uint8_t flag field in it, where only one
bit was used to flag that a proc was "local". In that context, "local" was
constrained to mean "local to this node".
This commit provides a greater degree of granularity on the term "local", to include tests
to see if the proc is on the same socket, PC board, node, switch, CU (computing
unit), and cluster.
Add #define's to designate which bits stand for which local condition. This
was added to the OPAL layer to avoid conflicting with the proposed movement of
the BTLs. To make it easier to use, a set of macros have been defined - e.g.,
OPAL_PROC_ON_LOCAL_SOCKET - that test the specific bit. These can be used in
the code base to clearly indicate which sense of locality is being considered.
All locations in the code base that looked at the current proc_t field have
been changed to use the new macros.
Also modify the orte_ess modules so that each returns a uint8_t (to match the
ompi_proc_t field) that contains a complete description of the locality of this
proc. Obviously, not all environments will be capable of providing such detailed
info. Thus, getting a "false" from a test for "on_local_socket" may simply
indicate a lack of knowledge.

properly at all. NetEffect's current driver (OFED 1.4.0) will return
a CONNECT_ERROR event to the initiator rather than the REJECTED event.
Doh! Additionally -- unfortunately -- NetEffect's vendor_id and
vendor_part_id are reported as 0 in OFED 1.4.0, so we can't
automatically detect these cards and work around the problem. So all
we can do is add a new MCA parameter
(btl_openib_connect_rdmacm_ignore_connect_errors -- yes, it's long on
purpose ;-) ) that says that if we get a CONNECT_ERROR, bascially
treat it exactly as a REJECT for the WRONG_DIRECTION reason (which is
a "good" reject). This allows OMPI to function with NetEffect/Intel
cards on OFED 1.4.0.
Note that NetEffect has been bought by Intel; I'm waiting for
information from them to update the ini file for their new OUI/PCI
ID's and/or new vendor_part_id values.

Fix a mistake in the dpm that hardcoded the update of routes to the HNP. This needs to be done by the individual routing modules so they can take whatever action is required - which will usually include updating the HNP, but might not...and might include additional steps. New routing modules are coming that violated this assumption, so it had to be moved back into init_routes.
All current routed modules know what to do - anyone with routed modules not in the current trunk may need to adjust them (see any of the current routed modules for examples of what to do).
