Originally udcm acks used the immediate data to indicate which message was
being acknowleged. This data was (mysteriously) junk when using QLogic HCAs so I
updated udcm to use the source info (slid, qp, etc) to determine which message was being
acked. This works as long as we don't have two messages simultaneously in flight
to a particular peer and then loose the first of the two messages. The chances of this
happening are tiny. To fix this case I updated the udcm message header to include
a pointer to the in flight message. This pointer is then sent back to the sending
process to ack receipt.

This commit updates the udcm cpc to support xrc. The steps followed by udcm
mimic those in the removed xoob cpc. This update has been tested with both XRC
and RC.
Mellanox, this is intended to go into 1.7.4. Please review carefully and let
me know if there are any issues.

(aka the root). This commit is based on a patch provided by Pierre
Jolivet.
Fix all the output to match the failing MPI call.

- added preprocessor conditional for vt_cupti_events_enabled
(fixes compile error when CUDA-RT wrapper are enabled and CUPTI is disabled (as reported at: https://svn.open-mpi.org/trac/ompi/changeset/29752 by Jörg Bornschein))

Fixed warnings about the need of the 'subdir-objects' option when using Automake v1.14.
Due to a bug in Automake (see http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928) the 'subdir-objects' option cannot be enabled.
To get around this problem external sources files are sym linked in the current build directory (as done in ompi/mpi/c/profile) to lead Automake to believe that all source files are in the same directory.
This commit was SVN r29732.
To support the new mpool two changes were made to the mpool infrastructure:
1) Added an mpool flag to indicate that an mpool does not need the memory
hooks to use the leave pinned protocols. This flag is checked in the
mpool lookup.
2) Add a mpool context to the base registration. This new member is used
by the udreg mpool to store the udreg context associated with the
particular registration. The new member will not break the ABI
compatibility as the new member is only currently used by the udreg
mpool.
Dynamics support for Cray systems makes use of the global rank provided by
orte to give the ugni library a unique rank for each process. Dynamics
support is not available under direct-launch (srun.)
