This adds a method to LinkFilter to build the query conditions necessary to properly use it, and adjusts code to use it. This also takes the opportunity to clean up the calculation of el_index: IPs are handled more sensibly and IDNs are canonicalized. Also weird edge cases for invalid hosts like "http://.example.com" and corresponding searches like "http://*..example.com" are now handled more regularly instead of being treated as if the extra dot were omitted, while explicit specification of the DNS root like "http://example.com./" is canonicalized to the usual implicit specification. Note that this patch will break link searches for links where the host is an IP or IDN until refreshExternallinksIndex.php is run. Bug: T59176 Bug: T130482 Change-Id: I84d224ef23de22dfe179009ec3a11fd0e4b5f56d
