Fix for TIMEAVG aggregation.

After the patch is installed, server data for the month and year has to be updated. Only some data
types need to be updated.

Log on to a client and check the directive

STORAGE_FILE_SPACE_PERIOD <period>      #data type 29
STORAGE_FILE_SYSTEMS_PERIOD <period>       #data type 24
STORAGE_QUOTA_PERIOD <period>          #data type 40

in /etc/opt/openit/openit.cfg.

To update disk utilization data, check the server directive:

DISK_UTIL_INTERVAL <period>     #data type 59

in /etc/opt/openit/openit.cfg.

Only the data type numbers found in the database need to be updated. And only these four data types.

If a directive is "daily" (or "da") the data collection interval is 86400. If the directive is this
number, this number is the interval. Otherwise it is weekly interval, 604800. It is adviced to take
a backup of the database directories for these data types. Run as the "openit" use for each relevant
data type:

/opt/openit/bin/add --redo --datatype <data type> --resolution <interval>

The included summasummarum will check every record it processes and
skip records with incorrect format, i.e. missing fields or too many
fields. It will give warnings to indicate which fields has been
skipped.

Also, two new options are included to allow activation of behavior on
client and server. This behavior will be triggered by patch 591 and
592.

NOTE: The C++ summasummarum is turned on by default by this
patch. If it is not wanted, turn it off by running:

chmod a+x /opt/openit/libexec/bin/summasummarum
chmod a-x /opt/openit/libexec/*/bin/summasummarum

Support for daily and weekly data from client laying in a time zone
east of the server. Such data used to be shifted to an earlier time
stamp. Now the client data of day and week interval is converted to
11:00 UTC. This is converted back to localtime 00:00 on the server.

This patch includes a summasummarum written in C++. For 64bit
platforms it will be able to use more memory than 4GB. This may be
needed in large installations.

This patch is probably most useful on servers, although it can also be
installed on clients.
