Ticket 419 - logconv.pl - improve memory management
Bug Description: logconv.pl memory usage is very high, and doesn't
appear to be efficient.
Fix Description: For verbose stats/hashes/arrays we now write this
information to disk, and read it in and process it
when printing the report. This dramatically improved
memory growth when dealing with larger and larger log sets.
Also updated the oids which some were incorrect, but
many new oids were missing. Added stats for "Paged Searches",
and "Max BER size exceeded".
Finally, renamed most variables to be readable names,
removed redundant counters, and other generic imrpovements.
