b06d92bdab OpenIB BTL has three channels through which data can be received (eager rdma, 
high prio QPs and low prio QPs) and because not all of them are polled each time
progrgess() is called (to save on latency) starvation is possible. The commit
fixes this. Now each channel is polled, but higher priority channels are polled
more often. Three new parameters are introduced that control polling ratios 
between different channels.

a9f864d15c If there is an eager rdma credit, but there is no WQE to send a packet we add it 
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.

6a2d210b7d Use OMPI object system to make fragment hierarchy more object oriented. The 
main idea (except of cleanup) is to save on initialisation of unneeded fields

50bae9c603 Bring in the modular-wireup stuff for the openib BTL (from 
/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.
