Allow for non-infiniband RPM package builds once more

If configure fails to find useable infiniband headers and libs,
we should not attempt to produce RPM packages.  Simplify and as
a result resolve a problem with sharing package file lists with
the Debian packages (infiniband files ending up in -libs).
Update test qa/292 to handle pre-existing pmcd pmDebug settings
pmdagfs2: changes to help with SAS calibration workload

Made changes to lock_time.c to actively call PMDA_CACHE_REORG before
each collection run, this improves throughput and reduces calculation
time in environments where there are an extremely high number of
locks worth recording.

Also made changes to COUNT_THRESHOLD to be more strict with regards
to newer locks (improving filtering).
