Port numbers need to be unique within each physical IB device (md),
otherwise connection requests between multiple clients of the same
proxy server can be matched incorrectly.

Add configuration files for new Proxy RDMA/SCIF Provider
This proxy RDMA provider is a interbus service within a platform
to enable offloading of RDMA writes from a small core (MIC) to
large core resource. Data sourced on a MIC that is
destined for remote nodes on the fabric will be transfered
to large core via SCIF and than to remote node.

The dat.conf includes both v1 and v2 device entries to insure

commom: add cm, link, and diag event counters in IB extended builds
Add additional event monitoring capabilities during runtime to help
isolate issues during scaling in lieu of logging/printing warning
messages. Counters have been added to provider CM services and counters
have been added and mapped to sysfs ib_cm, device port and device
diag counters. ibdev_path is used for device sysfs counters.
uDAPL CM events are tracked on a per IA instance via internal
provider counters. The ib_cm, link, and diag events are tracked on a
per platform basis via sysfs. For these running counters a start
and stop function is provided for sampling and mapping to DAPL
64 bit counters. All counters, along with new start and stop functions,
are provided via dat_ib_extensions.h. New IB extension version is 2.0.7
New DCNT_IA_xx counters include 40 cm, 9 link, and 9 diag types.
To enable new counters (default build is disabled):
./configure --enable-counters
New bitmappings have been added to DAPL_DBG_TYPE environment
variable to automatically start/stop counters and log
errors if counters are enabled. The following will control
CM, LINK, and DIAG respectively:
