A recent change in processing of map data introduce a problem with handling
the '|' character in map output. This patch fixes this problem.

The patch also includes all previous update for map_maintainer since release
6.2

The basic "map" function supported to clean up errors in data from
input sources is currently restricted to replacing the complete output
values. This is inflexible and requires specific entries for every output
value that require modification.

This update adds two new correction functions to mapfilters.cfg 

1. replace
This function allows setting up a proper substring replacement. The
replacement value is still restricted to a "literal", but only the matched
string will be replaced, not the entire data field.

This function also allows substring deletion (by leaving the second 
parameter empty)

2. extract
This function allows extracting one substring from a data field for
output

Detailed documentation for this functionallity can be found in
the included sample configuration file provided in the patch
(mapfilters.cfg.new). 

General Description:
Fix for map_maintainer producing duplicate entries

Detailed Description:
map_maintainer produces mappings with duplicate entries which causes inaccurate reports when using
these mapping files.This patch contains the fix so that map_maintainer will produce unique mapping
entries for virtual, license-single and license-multi type mappings.

General Description: Fix for map_maintainer long processing time

Detailed Description: 
Active directory records that has no proper unique id causes too much processing time of
map_maintainer. To prevent this issue, map_maintainer will skip the generation of empty id and log a
warning about the number of ignored records in debug.
