Update to avoid a conflict with an internal perl function. Needed when
updating to new perl version.

NOTE: If an OpeniT client resides on the same host, patch #396 must
be installed together with patch #397.

If something connects to the Open iT server and then breaks protocol
(as done by telnet to the port and typing some random characters),
we will now log the address of the remote client as well in the
Open iT server log.

Cleanup: .temp files that have been read are now removed only if they
have not been modified during the last 48 hours. Files that has not
been read will only be removed if they are older than 7 days.

A slight improvement in protocol when exchanging string/file
sizes in the protocol. The protocol will now try to
send size values in single chunks and not byte by byte. Some
extra error handling has also been added.

This patch adds two configuration directives to the server which both affect the
"_archive_license_data"-cronjob.

- ARCHIVE_DATA_INTERVAL, which determines how often data should be archived, with the
values determining how many seconds should pass between each archival. 3600 = one hour,
86400 = one day. 86400 is the default used if the directive isn't set.

- ARCHIVE_DATA_OFFSET, which determines how many seconds after each period-start the
job should be started. The default is 15000, which equals 4 hours and 10 minutes.

When saving a report template with title containing a slahs, an error would occur since the
title is used as the filename for the report, and Unix does not allow slashes in filenames.

This patch makes sure that any slashes in the filename are converted to dashes (-) before
attempting to save it to file.

Removes tree part of quota identifier to be able to map identifier
into mount point name. In addition a small fix for adjusting time
of week data output.
