Update to avoid a conflict with an internal perl function. Needed when
updating to new perl version. The patch also includes small pacct fix.

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

This patch adds an additional configuration parameter

  PACCT_OFFSET

to

  /etc/opt/openit/openit.cfg

which can be used to tune the timing of pacct data collection.
This parameter takes an offset value (in seconds) that will be
added to the default collection times specified by PACCT_RESTART.

E.g

  PACCT_RESTART   86400
  PACCT_OFFSET     7200

will make pacct be collected once every 24 hours. The collection
is shifted 2 hours + a random offset (1-3600 seconds) after midnight.
The random offset is not configurable and is intended to help prevent
all clients from trying to transfer data at the same time.

Extended pacct: End time as calculated from ps output is checked not
to be in far future.  The log message given when a field in the ps
output it too wide, is now a debug message, not a warning. This will
reduce the number of monips entries in syslog.

In the latest version of the sysstat package (which contains sar)
the memory usage fields have been changed a bit. This update
adds checking of the field headers to determine wheter it's
systat 5 or an earlier version and sets field position according
to this test.

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.

Processes recorded with pacct and ps are merged in a better manner.

The number of header lines for AIX 5 sar output varies. Updated 
parsing to handle any number of header lines in output.
