Enhanching the code to fix the lookup will rapidely slow down the lookup speed. Because using
the GeoIP2 module is no option ( the reasons have been described in the commit message which will
now reverted), we have decided to temporary switch back to the old module until a nice solution has
been found.
This reverts commit ff21ff90d2.

Drop the usage of the old legacy GeoIP perl module which was not able to handle the
new GeoLite2 databases.
Write some code to directly access the databases and extract the required data.
Usage of the GeoIP2 perl module would provide a lot of more functionality which is not
used/needed. Unfortunately ir requires at lot of additional perl modules which are
not available on IPFire and would only be build and shipped for this module. Buildig all
of them will slow down the entire build process, mess up the system and requires a lot
more space on disk.

In commit ea5c8eeb83 the taken settings

The Downloader now uses this file to read-in which ruleset should be used
and downloaded.

I added a function to determine the number of cores.
Now the number of squid processes will be equal to the number of logical cores.
Further I removed the possibility of changing the number
of squid processes in the proxy.cgi

Download the requested rules tarball into a temporay file

The get_available_network_zones() function uses the /var/ipfire/ethernet/settings
file and translates the configured mode into an array, which contains the names
of the configured network zones.
The array will be returned and easily can be used to loop over this list of
available network zones and perform any kind of actions in other scripts.
