general-functions.pl: Replace lots of broken network code.
...
The state of some code especially in general-functions.pl
is in such a bad shape and faulty.
This is a first step that replaces some of the network
functions with those who have been tested and work for
undefined inputs.
The old functions have been left in place as stubs
and must be removed at some time.

firewall: Fix creation of automatic rules for the firewall.
...
If the firewall is part of a local network (e.g. GREEN),
we automatically add rules that grant/forbid access for the firewall,
too.
This has been broken for various default policies other than ALLOWED.

firewall: Fix perl coding error.
...
Example:
my @as = (1, 2, 3);
foreach my $a (@as) {
$a += 1;
print "$a\n";
}
$a will be a reference to the number in the array and not
copied. Therefore $a += 1 will change the numbers in the
array as well, so that after the loop the content of @as
would be (2, 3, 4).
To avoid that, the number needs to be copied into a new
variable like: my $b = $a; and we are fine.
This caused that the content of the @sources and @destinations
array has been altered for the second run of the loop and
incorrect (i.e. no) rules were created.

Firewall: DNAT - Show right DNAT interface in ruletable
...
Now:
When using a hostgroup as source there are all corresponding DNAT
interfaces shown in ruletable depending on the entries in the group.
When in DNAT area "-automatic" is selected, the DNAT interfaces are
shown as IP-Addresses, else they are shown as "ORANGE","GREEN","BLUE"...
BUGFIX: When there is a MAC address used in a sourcegroup, the rules could not be set. Now MAC addresses get allways the public interface as DNAT
