(e.g. transitivity lemmas) and fix bug #2207, avoiding the generation of
useless eta-redexes during type class instance resolution.

- New (modular) mergesort purely using structural recursion
- Move of the (complex) notion of permutation up to setoid equality
formerly defined in Permutation.v to file PermutSetoid.v
- Re-use of the file Permutation.v for making the canonical notion
of permutation that was in List.v more visible
- New file Sorted.v that contains two definitions of sorted:
"Sorted" is a renaming of "sort" that was defined in file
Sorting.v and "StronglySorted" is the intuitive notion of sorted
(there is also LocallySorted which is a variant of Sorted)
- File Sorting.v is replaced by a call to the main Require of the directory
- The merge function whose specification rely on counting elements is moved
to Heap.v and both are stamped deprecated (the sort defined in
Heap.v has complexity n^2 in worst case)
- Added some new naming conventions
- Removed uselessly-maximal implicit arguments of Forall2 predicate

in */*/vo.itarget
On the way: no more -fsets (yes|no) and -reals (yes|no) option of configure
if you want a partial build, make a specific rule such as theories-light
Beware: these vo.itarget should not contain comments. Even if this is legal
for ocamlbuild, the $(shell cat ...) we do in Makefile can't accept that.

avoiding the introduction of eta-redexes. Prioritize hints over intros
in typeclass resolution to profit from that.
Add a minor fix in coqdoc by F. Garillot.

substitution. Makes unification succeed a bit more often, hence auto
works better in some cases.
- Backtrack the changes of auto using Hint Unfold to do more delta and add
a new tactic "new auto" which does that, for compatibility.
The first fix may have a big impact on the contribs, whereas the second
should make them compile again... we'll see.

debugging and printing hint databases
- Typeclasses unfold now correctly adds _global_ unfold hints.
- New tactic autosimpl to do simplification using the declared unfold
hints in given hint databases.
- Work on auto-modulo-some-delta (the declared Unfold constants),
actually used mostly if the goal contains evars, as Hint_db.map_auto
does not work up-to any conversions (yet).
- Fix GenMul which was using the old semantics of failing early because
of variance checks, which is not possible in the new implementation.
- Restrict when reflexive_morphism may be used using an extern tactic.

* "f_equal" is now a tactic in ML (placed alongside congruence since
it uses it). Normally, it should be completely compatible with the
former Ltac version, except that it doesn't suffer anymore from the
"up to 5 args" earlier limitation.
* "revert" also becomes an ML tactic. This doesn't bring any real
improvement, just some more uniformity with clear and generalize.
* The experimental "narrow" tactic is removed from Tactics.v, and
replaced by an evolution of the old & undocumented "specialize"
ML tactic:
- when specialize is called on an hyp H, the specialization is
now done in place on H. For instance "specialize (H t u v)"
removes the three leading forall of H and intantiates them by
t u and v.
- otherwise specialize still works as before (i.e. as a kind of
generalize).
See the RefMan and test-suite/accept/specialize.v for more infos.
Btw, specialize can still accept an optional number for specifying
how many premises to instantiate. This number should normally
be useless now (some autodetection mecanism added). Hence this
feature is left undocumented. For the happy few still using
specialize in the old manner, beware of the slight incompatibities...
* finally, "contradict" is left as Ltac in Tactics.v, but it has
now a better shape (accepts unfolded nots and/or things in Type),
and also some documentation in the RefMan
