Move internal modules in a separate as_ namespace

There are few things I'm not totally happy with:
- some documentation is duplicated in the main .mli and the internal ones
- there are still some internal types which appears in public interface, because of the custom actions for generate source file. Need more examples there to get the right public API.
Move some docs around
Names should come first
