Emilio Cobos Álvarez 601f952a28 Bug 1688925 - Move DNS prefetch state out of Link into its own super-class. r=smaug,edgar
I made sure that this didn't grow HTMLAnchorElement, though if we don't
care too much (sizeof(HTMLAnchorElement) is 176 right now) we might want
to remove ToSupportsDNSPrefetch and such.

This fixes a subtle bug where OnDNSPrefetchRequested wasn't being called
when IsNeckoChild was true.
