Subject: [PATCH 27/28] Ticket 47533 logconv: some stats do not work across server restarts

https://fedorahosted.org/389/ticket/47533
Reviewed by: mreynolds (Thanks!)
Branch: master
Fix Description: Most of the stat hashes use connid,opid as the hash key.
The connid,opid are not unique because the server recycles connection ids
when the server restarts.  The solution is to use a triplet of
$serverRestartCount,$connid,$opid
as the hash key.  This uniquely identifies a particular log event over
restarts.  There is also some additional cleanup that needs to be done when
the server is reset - returning fds, marking connections as closed, etc.
Also fixed some gmtime handling - we were doing too many conversions.
This fix adds another command line option - -U - for a summary of search
filters which are unindexed or have unindexed components.  The full detailed
report is just too much data.
Platforms tested: RHEL6 x86_64
Flag Day: no
Doc impact: no
