[PATCH] location-functions.pl: Recognise XD / LOC_NETWORK_FLAG_DROP

["Peter Müller" <peter.mueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 2189 bytes --]

This enables creating firewall rules using the special country code "XD"
for hostile networks safe to drop and ipinfo.cgi to display a meaningful
text for IP addresses having this flag set.

At the moment, the "LOC_NETWORK_FLAG_DROP" is not yet populated, but
will be in the future (as soon as libloc 0.9.9 is released and running
in production).
