LinkFilter: use wfMakeUrlIndexes in makeLikeArray
De-duplicate the link munging logic shared by wfMakeUrlIndexes
(used to index links in the first place) and LinkFilter::makeLikeArray
(used when searching for those links). Searching for links with
a port number is now possible, as long as you specify the port
or a subdomain wildcard. Also, searching for mailto links with
no @ sign now distinguishes between single domains and subdomains.
