This patch splits pretty printing representation from IO operations.
- `Pp` is kept in charge of the abstract pretty printing representation.
- The `Feedback` module provides interface for doing printing IO.
The patch continues work initiated for 8.5 and has the following effects:
- The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`,
`pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`,
`msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be
used instead.
- Feedback provides different backends to handle output, currently,
`stdout`, `emacs` and CoqIDE backends are provided.
- Clients cannot specify flush policy anymore, thus `pp_flush` et al are
gone.
- `Feedback.feedback` takes an `edit_or_state_id` instead of the old
mix.
Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

- Universes are now represented in the VM by a structured constant containing the
global levels. This constant is applied to local level variables if any.
- When reading back a universe, we perform the union of these levels and return
a [Vsort].
- Fixed a bug: structured constants could contain local universe variables in
constructor arguments, which has to be prevented.
Was showing up for instance when evaluating [cons _ list (nil _)] with
a polymorphic [list] type.
- Fixed a bug: polymorphic inductive types can have an empty stack.
Was showing up when evaluating [bool] with a polymorphic [bool] type.
- Made a few cosmetic changes.
Patch written with Benjamin Grégoire.

polymorphic definitions.
- This implementation passes universes in separate arguments and does not
eagerly instanitate polymorphic definitions.
- This means that it pays no cost on monomorphic definitions.

Rename some functions, remove dead code related to (previously deprecated, now
removed) option Set Boxed Values.

1- Management of the name-space in a modular development / sharing of non-logical objects.
2- Performance of atomic module operations (adding a module to the environment, subtyping ...).
1-
There are 3 module constructions which derive equalities on fields from a module to another:
Let P be a module path and foo a field of P
Module M := P.
Module M.
Include P.
...
End M.
Declare Module K : S with Module M := P.
In this 3 cases we don't want to be bothered by the duplication of names.
Of course, M.foo delta reduce to P.foo but many non-logical features of coq
do not work modulo conversion (they use eq_constr or constr_pat object).
To engender a transparent name-space (ie using P.foo or M.foo is the same thing)
we quotient the name-space by the equivalence relation on names induced by the
3 constructions above.
To implement this, the types constant and mutual_inductive are now couples of
kernel_names. The first projection correspond to the name used by the user and the second
projection to the canonical name, for example the internal name of M.foo is
(M.foo,P.foo).
So:
*************************************************************************************
* Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values *
*************************************************************************************
Map and Set indexed on names are ordered on user name for the kernel side
and on canonical name outside. Thus we have sharing of notation, hints... for free
(also for a posteriori declaration of them, ex: a notation on M.foo will be
avaible on P.foo). If you want to use this, use the appropriate compare function
defined in name.ml or libnames.ml.

No more time explosion (i hoppe) when using modules i have re-implemented atomic
module operations so that they are all linear in the size of the module. We also
have no more unique identifier (internal module names) for modules, it is now based
on a section_path like mechanism => we have less substitutions to perform at require,
module closing and subtyping but we pre-compute more information hence if we instanciate
several functors then we have bigger vo.
Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions
above, i will work on it soon...

Part contre ces cas sont detruis dans les "Definition"
(pas dans les "Lemma") je comprends pas ou ils sont enlev'e...
Si une id'ee ...
- Correction d'un bug dans vm_compute plusieurs fois signal'e par Roland.
- Meilleur compilation des coinductifs, on utilise maintenant vraimment
du lazy.
- Enfin un peu plus de doc dans le code de la vm.
