[api] Remove type equalities from API.

This ensures that the API is self-contained and is, well, an API.
Before this patch, the contents of `API.mli` bore little relation with
what was used by the plugins [example: `Metasyntax` in tacentries.ml].

Many missing types had to be added.

A sanity check of the `API.mli` file can be done with:

`ocamlfind ocamlc -rectypes -package camlp5 -I lib API/API.mli`
