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:

   DAPL_DBG_TYPE_CM_ERRS	= 0x080000,
   DAPL_DBG_TYPE_LINK_ERRS	= 0x100000,
   DAPL_DBG_TYPE_DIAG_ERRS	= 0x400000,
