Introduced in FlaggedRevs with Idbdab9a7396 (6bfd276e64), and I've
migrated consumers away from the singleton in I192b962147 (5ee96e5ca7)
and I04fdbd497b8 (bbdfc4c024).
The one thing that remains global by default is the context, but
VE already avoids that with setContext, and (correctly) restores this
afterward since the FlaggablePageView object is re-used by title.
That's exactly as terrible as it sounds, but at least it's a bit more
visible after my refactor.

This copies the Parsoid extension code into includes/VEParsoid
to allow a "one extension, zero-configuration" install of
VisualEditor for MW's LTS release. The Parsoid code has been
re-namespaced (`VEParsoid` instead of `MWParsoid`) to avoid
autoloader conflicts if you actually install Parsoid as an
extension (as we do in Wikimedia production). Similarly, we
arrange that the ServiceWiring and RestRoutes configurations
are skipped unless running in zeroconf mode, to avoid
conflicts with the Parsoid extension.
This import matches Parsoid commit b30f223.
