Drop compat "gateway" name

Back in 5248e7e1f11aba6859de0b28f0dd3778b22842f2 (July 2017) we moved over to
"_gateway", with the old name declared to be temporary measure. Since we're
doing a bunch of changes to resolved now, it seems to be a good moment to make
this simplification and not add support for the compat name in new code.
