BinPos now contain a sub-module Pos, in which are placed functions
like add (ex-Pplus), mul (ex-Pmult), ... and properties like
add_comm, add_assoc, ...
In addition to the name changes, the organisation is changed quite
a lot, to try to take advantage more of the orders < and <= instead
of speaking only of the comparison function.
The main source of incompatibilities in scripts concerns this compare:
Pos.compare is now a binary operation, expressed in terms of the
ex-Pcompare which is ternary (expecting an initial comparision as 3rd arg),
this ternary version being called now Pos.compare_cont. As for everything
else, compatibility notations (only parsing) are provided. But notations
"_ ?= _" on positive will have to be edited, since they now point to
Pos.compare.
We also make the sub-module Pos to be directly an OrderedType,
and include results about min and max.

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

As show by contrib TreeAutomata, the Peqb now placed in BinPos
was using 1st arg as "struct", instead of 2nd arg as earlier.
Fix that, and remove the "Import BinPos BinNat" hack in Ndec
(merci Hugo :-).

+ adaptation of {Nat,N,P,Z,Q,R}_as_DT for them to provide both eq_dec and eqb

The compare functions are still functions-by-tactics, but now their
computational parts are completely pure (no use of lt_eq_lt_dec in
nat_compare anymore), while their proofs parts are simply calls
to (opaque) lemmas. This seem to improve the efficiency of sets/maps,
as mentionned by T. Braibant, D. Pous and S. Lescuyer.
The earlier version of nat_compare is now called nat_compare_alt,
there is a proof of equivalence named nat_compare_equiv.
By the way, various improvements of proofs, in particular in Pnat.

* le type ad des adresses est maintenant un alias vers
le N de NArith, qui lui est isomorphe.
* toutes les operations sur ces adresses (p.ex. un xor
bit a bit) sont maintenant dans de nouveaux fichiers du
repertoire NArith.
* Intmap utilise maintenant le meme type option que le
reste du monde
* etc etc...
Tout ceci ne preserve pas forcement la compatibilite. Les 4 contribs
utilisant Intmap sont adaptees en consequence. Me demander si besoin
ma moulinette d'adaptation (incomplete).
