Almost all of ml4 were removed in the process. The only remaining files
are in the test-suite and probably need a bit of fiddling with coq_makefile,
and there only two really remaning ml4 files containing code.

longer use camlp4.

We do up to `Term` which is the main bulk of the changes.

I.e., do not set local flag to false when in a section since
compatibility tells discharge of hints is not supported.

In the previous setting, all plugins/ltac/*.cmxs except ltac_plugin.cmxs
(for instance coretactics.cmxs, g_auto.cmxs, ...) were utterly bogus :
- wrong -for-pack used for their inner .cmx
- dependency over modules not provided (for instance Tacenv, that ends
up being a submodule of the pack ltac_plugin).
But we were lucky, those files were actually never loaded, thanks to the
several DECLARE PLUGIN inside coretactics and co, that end up in ltac_plugin,
and hence tell Coq that these modules are already known, preventing
any attempt to load them.
Anyway, this commit cleans up this mess (thanks PMP for the help)

Reminder of (some of) the reasons for removal:
- Despite the claim in sigma.mli, it does *not* prevent evar
leaks, something like:
fun env evd ->
let (evd',ev) = new_evar env evd in
(evd,ev)
will typecheck even with Sigma-like type annotations (with a proof of
reflexivity)
- The API stayed embryonic. Even typing functions were not ported to
Sigma.
- Some unsafe combinators (Unsafe.tclEVARS) were replaced with slightly
less unsafe ones (e.g. s_enter), but those ones were not marked unsafe
at all (despite still being so).
- There was no good story for higher order functions manipulating evar
maps. Without higher order, one can most of the time get away with
reusing the same name for the updated evar map.
- Most of the code doing complex things with evar maps was using unsafe
casts to sigma. This code should be fixed, but this is an orthogonal
issue.
Of course, this was showing a nice and elegant use of GADTs, but the
cost/benefit ratio in practice did not seem good.

This commit is essentially moving files around. In particular, the corresponding
plugin still relies on a mllib file rather than a mlpack one. Otherwise, this
causes link-time issues for third-party plugins depending on modules defined
in the Ltac plugin.
