Make the Coq codebase independent from Ltac-related code.

We untangle many dependencies on Ltac datastructures and modules from the
lower strata, resulting in a self-contained ltac/ folder. While not a plugin
yet, the change is now very easy to perform. The main API changes have been
documented in the dev/doc/changes file.

The patches are quite rough, and it may be the case that some parts of the
code can migrate back from ltac/ to a core folder. This should be decided on
a case-by-case basis, according to a more long-term consideration of what is
exactly Ltac-dependent and whatnot.
