For F(X:T), the application !F M works as F M, except that if module type T
contains some "Inline" annotations, they are not taken in account when substituting
X with M in F. See forthcoming commits for examples of use for this feature.

Syntax Include Type is still active, but deprecated, and triggers a warning.
The syntax M <+ M' <+ M'', which performs internally an Include, also
benefits from this: M, M', M'' can be independantly modules or module type.

- backtrack on incompatibility introduced in intro while trying to
simplify the condition about when to restart the subscript of a name
(the legacy says: find a new name from x0 if the name xN exists in
the context but find a new name from xN+1 if the name xN does not
exists in the context but is a global to avoid).
- made the names chosen by "intro" compliant with the ones printed in
the goal and used for "intros until" (possible source of rare
incompatibilities) [replaced the use of visibly_occur_id for
printing the goal into a call to next_name_away_in_goal]
- also made the names internal to T in "T -> U" printed the same in
the goal as they are while printing T after it is introducted in the
hypotheses [non contravariant propagation of boolean isgoal in
detype_binder]
- simplified a bit visibly_occur_id (the Rel and Var cases were useless as
soon as the avoid list contained the current env); still this function is
costly with polynomial time in the depth of binders
- see file output/Naming.v for examples

If you have some Module Type F (X:Sig), and you are in a Module Type
containing everything required to satisfy Sig (typically thanks to
some earlier Include), then you can say Include Self Type F, and voila,
objects of F are now added in your context, instantiated by local objects.
Same behavior (hopefully) for modules and functors when using Include Self F.
This experimental new command allows to easily produce static signatures
out of functorial ones:
Module Type F_static. Include Sig. Include Self F. End F_static.
... is similar to ...
Module Type F_static. Declare Module X:Sig. Include F X. End F_static.
... but without the pollution of this artificial inner module X.
This allow to split things in many othogonal components, and then mix them.
It is a lightweight way to tackle the "diamond problem" of modular
developpements without things like "overlapping" Include's (planned, but
not yet there). See next commit for an example of use.
Thanks to Elie for the debugging of my first ugly prototype...
NB: According to Yann R.G., this is related with Scala's Traits.

not taking in account equivalent names of inductive types.

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 ...).

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...

very useful in practice but as soon as let-in's were not forbidden in
the internal data structure, better to do it. Moreover, this gets
closer to the view were inductive definitions are uniformly built from
"contexts". (checker not changed!)

(uniformisation of function names, classification). One of the most
visible change is the renaming of section_path into full_path (the
use of name section was obsolete due to the module system, but I
don't know if the new name is the best chosen one - especially it
remains some "sp" here and there).
- Simplification of the interface of classify_object (first argument dropped).
- Simplification of the code for vernac keyword "End".
- Other small cleaning or dead code removal.

predicate called from proof refiner was failing because it was not
aware of evars instantiation; I added a nf_evar in 8.2 branch but for
the trunk, I propose to remove the elimination predicate
well-formation test; we therefore assume that tactics build correct
elimination predicates in Case, is it not too much demanding?).
- Seized the opportunity to remove dead kernel code about non dependent
elimination predicates (all predicates are stored dependent by
default since a few years now).
- Anecdotic complement to commit 12229 (removal of obsolete comment).

- Primitive setup for firing typeclass resolution on-demand: add a flag to
control resolution of remaining evars (e.g. typeclasses) during
unification.
- Prevent canonical projection resolution when no delta is allowed
during unification (fixes incompatibility found in ssreflect).
- Correctly check types when the head is an evar _or_ a meta in w_unify.
Move [isEvar_or_Meta] to kernel/term.ml, it's used in two places now.

This commit concerns about the first half of the useless code
mentionned by Oug for coqtop (without plugins). For the moment,
Oug is used in a mode where any elements mentionned in a .mli
is considered to be precious. This already allows to detect and
remove about 600 lines, and more is still to come.
Among the interesting points, the type Entries.specification_entry
and its constructors SPExxx were never used. Large parts of cases.ml
(and hence subtac_cases.ml) were also useless.

* a small shell script ./build to drive ocamlbuild
* rules for all the binaries (apart from coqide and coqchk)

* generalize the use of .mllib to build all cma, not only in plugins/
* the .mllib in plugins/ now mention Bruno's new _mod.ml files
* lots of .cmo enumerations in Makefile.common are removed, since
they are now in .mllib
* the list of .cmo/.cmi can be retreive via a shell script line,
see for instance rule install-library
* Tolink.core_objs and Tolink.ide now contains ocaml _modules_, not
_files_
* a -I option to coqdep_boot allows to control piority of includes
(some files with the same names in kernel and checker ...)
This is quite a lot of changes, you know who to blame / report to
if something breaks.
... and last but not least I've started playing with ocamlbuild.
The myocamlbuild.ml is far from complete now, but it already allows
to build coqtop.{opt,byte} here. See comments at the top of
myocamlbuild.ml, and don't hesitate to contribute, either for completing
or simplifying it !
