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.

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.

main idea (except of cleanup) is to save on initialisation of unneeded fields
and to use C type checking system to catch obvious errors.
