add ipinfo_io_whois.c

[revrsefr]

I removed the old ipinfo_whois file and removed the curl things to use unrealircd API.

Do you still want this merged? I ask because in 6.1.7+ we added ASN, and we already had country earlier.

When this was closed (which I take as a "no, this module is no longer needed") I forgot that we still had to remove the original module third/ipinfo_io_whois.c. So I did just now, in commit b14b15f with this message:

Remove third/ipinfo_io_whois since it is no longer needed.
This functionality is provided in UnrealIRCd itself using the
GeoIP API. UnrealIRCd 6.1.7 now supports "ASN" (which this
module provided as "org" I think) and we already had support
for "country". Ok, "region" / "city" is missing, but other
than that...
See #116 which was closed after asking if we still needed this.
Just didn't realize the old module was still in the repo...

I'm happy we have the ASN support nowadays :)

The city stuff could actually be added to the geoip modules, and then you need city databases, but I don't think many people need this, and these are generally not free or freely distributable. I'm happy to add support in unrealircd for parsing and showing it in some future patch but we won't ship by default with those db files, so.. it's not exactly high on my list.. I think most people can live without "city". The "country" and now "asn" since 6.1.7 is most useful though!
