Matthew Flatt 9cf6659bf0 avoid write-barrier memory protection for 'atomic-interior allocation 
Split 'atomic-interior allocation to separate pages from other 'interior
allocation, and do not page-protect 'atomic-interior memory. Otherwise,
atomic-interior memory passed from one place to another --- especially
via the `#:in-original-place?` option on foreign functions --- can crash
due to triggering a write barrier in the wrong place.

Commit c18f6e8d6d, which changed some cross-place arguments to Pango and
Cairo to be 'atomic-interior, exposed the problem.

Some indentation is left bad intentionally to minimize the diff.
