This patch replaces the intra process locking mechanism
with thread mutex's instead of semaphores.

The patch also fixes a problem with correct handling
of time zones for FLEXlm debug log data.

This patch adds a lock to the archiver binary that prevents
more than one instance from running simultainously. It also
limits the number of open output files to 8.

In addition the patch allows archiver to accept that the last
field in some recorder data may be empty.

An bug in filtrator causes problems when processing data
from more than one license type, E.g both "flex" and "lum"
data for the same period.

Please note that the new filtrator now requires multiple 
license clients for the same products to be setup with 
different offsets to guarantee correct behaviour, e.g if 
you have two clients for a set of products, one should be
setup without offset and the other with an offset set to 
half the polling interval.

This patches update the archiver binary with a version
that is better at handling seriously corrupt input
files.

This patches update the archiver binary to be able to handle
strings that contain unprintable characters.

Bug in filtrator caused error when calculating elapsed time for
hour 23 every day.
