RFE: Remove +ipv6 and make it default

[raimue (Rainer Müller)]

Some ports still have a +ipv6 variant. Most of them only pass --disable-ipv6/--enable-ipv6 to the configure script and do not add additional dependencies. As many other ports already provide support for IPv6 by default, I would like to remove +ipv6 altogether and support IPv6 by default also for these ports.

Affected ports:

bro	pmq@…	r44844
claws-mail	nomaintainer@…	r46897
curl	ryandesign@…	*1
djbdns	nomaintainer@…	*2

tin	nomaintainer@…	r46907
tin-devel	nomaintainer@…	r46907
tin-recent	vincent-opdarw@…	r44836
wireshark	opendarwin.org@…	r46908 (reverted r46911)
xchat2	afb@…,openmaintainer@…	r46909

• *1 = has other variant conflicting +ipv6
• *2 = custom patches
• *3 = false positive, has a +no_ipv6 variant

Please give feedback. I will go ahead and change nomaintainer/openmaintainer in a few days.

I committed some ports. I've updated the description above to reflect the current state. I did not touch ports which use patches for ipv6 support.

Please don't do wireshark (yes, replying after the fact)

[raimue (Rainer Müller)]

Bumped revisions (which I forgot) in r46912.
