Migration of the old mailing lists hosted on zarb.org to ml.mageia.org.

Things to do

decide names for the new lists
create the new lists on ml.mageia.org
split the list of people subscribed on old mailing lists in two parts :
- people with an identity account : subscribe them to the new mailing list
- people subscribed with a mageia.org: find their real email address in identity and subscribe them to the list with this address
- people without an identity account : send them an email about the new mailing list to tell them how to subscribe
send an email on the new lists to explain about the change
create lists for bugzilla emails, and update bugzilla accounts to send to the new lists
host mailing lists archives and http://archives.mageia.org/mailman/ and add redirect from http://www.mageia.org/mailman so that the links to mail archives keep working
update www and wiki links
