If there are multiple QP's, RDMACM will not send a message if the
qpnum != 0. In doing so, it will log an error unecessarily. This
removes that.
This commit was SVN r18363.
Add the logic to support using port numbers, instead of simply using
the IP address of the sending node to determine which endpoint to
connect. Since each process calls the cpc query function, it will
generate its own port to listen on thus enablign this to work.

for dynamic selection of cpc methods based on what is available. It
also allows for inclusion/exclusions of methods. It even futher allows
for modifying the priorities of certain cpc methods to better determine
the optimal cpc method.
This patch also contains XRC compile time disablement (per Jeff's
patch).
At a high level, the cpc selections works by walking through each cpc
and allowing it to test to see if it is permissable to run on this
mpirun. It returns a priority if it is permissable or a -1 if not. All
of the cpc names and priorities are rolled into a string. This string
is then encapsulated in a message and passed around all the ompi
processes. Once received and unpacked, the list received is compared
to a local copy of the list. The connection method is chosen by
comparing the lists passed around to all nodes via modex with the list
generated locally. Any non-negative number is a potentially valid
connection method. The method below of determining the optimal
connection method is to take the cross-section of the two lists. The
highest single value (and the other side being non-negative) is selected
as the cpc method.

should be passed via commandline. However, there is a slight coding
bug in the openib connect code. When registering the name of the
option, mca_base_param_reg_string will prepend the relevant info
("btl_openib_" in this case). The existing code will require
"btl_openib_btl_openib_connect" instead of "btl_openib_connect".
This patch corrects this.

to a pending queue of eager rdma QP instead of correct pending list. This patch
fixes this by getting reed of "eager rdma qp" notion. Packet is always send
over its order QP. The patch also adds two pending queues for high and low prio
packets. Only high prio packets are sent over eager RDMA channel.

one HCA. Multiple ports, LMC, multiple BTLs per one LID. Having only one CQ for
all of them substantially reduce polling time.

/tmp/jms-modular-wireup branch):
* This commit moves all the openib BTL connection code out of
btl_openib_endpoint.c and into a connect "pseudo-component" area,
meaning that different schemes for doing OFA connection schemes can
be chosen via function pointer (i.e., MCA parameter) at run-time.
* The connect/connect.h file includes comments describing the
specific interface for the connect pseudo-component.
* Two pseudo-components are in this commit (more can certainly be
added).
* oob: use the same old oob/rml scheme for creating OFA connections
that we've had forever; this now just puts the logic into this
self-contained pseudo-component.
* rdma_cm: a currently-empty set of functions (that currently
return NOT_IMPLEMENTED) that will someday use the RDMA connection
manager to make OFA connections.
