Patch 610 — Update on archiver: Ignore old recorder data

In the configuration file daft.conf, there can be added an optional object
'archiver.process-threshold.ignore-age()="0"{}'.
The default value is '0'. If this object contains a value other than '0', the archiver will ignore
all records with start age before this age (in days).
Only recorder data are affected.

Patch 608 — Fix for archiver.

Fixed a crash in archiver, when processing huge data, due to 'Out Of
Memory'.

NOTE: HP-UX does not have this fix. The binary from patch 597 is used.

Patch 597 — Fix for archiver: illegal recorderperiod measurements

Two fixes: Handling of records with negative measurements. Handling of
records passign midnight.
