This previously only worked if $wgLocalVirtualHosts was set, which
was too specific to check and not used by WMF. Use the more generic
WikiMap class.
Two methods have been added there to do the work of enumerating
canonical wiki farm URLs and checking them against a given URL.

If we don't have a valid canonical server and path to pass, there's no
point in returning a WikiReference that will fail in strange and unusal
ways.
This also documents that $wgServer/$wgCanonicalServer and $wgArticlePath
are required in SiteConfiguration.

The mapping is not very good, but should be good enough, given
that only the URL parts are really being used.

Given that the class is not constructed anywhere outside
of core the constructor can be altered without having to
worry about b/c.
