Title: allow interner cache to be shared across parsers (#3699)

This patch is to potentially fix (#3699). It allows the parser interner cache to be shared between multiple parsers on the same thread. I'm not quite sure what the consequences of this are, but most of the tests pass on my laptop (the failures already exist on incoming so I believe they are unrelated). `cargo install mongrel2` works as well.
