For instance inj_plus is now Nat2Z.inj_add

For instance, former Pplus_plus is now Pos2Nat.inj_add.
As usual, compatibility notation are provided.

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.

Initial plan was only to add shiftl/shiftr/land/... to N and
other number type, this is only partly done, but this work has
diverged into a big reorganisation and improvement session
of PArith,NArith,ZArith.
Bool/Bool: add lemmas orb_diag (a||a = a) and andb_diag (a&&a = a)
PArith/BinPos:
- added a power function Ppow
- iterator iter_pos moved from Zmisc to here + some lemmas
- added Psize_pos, which is 1+log2, used to define Nlog2/Zlog2
- more lemmas on Pcompare and succ/+/* and order, allow
to simplify a lot some old proofs elsewhere.
- new/revised results on Pminus (including some direct proof of
stuff from Pnat)
PArith/Pnat:
- more direct proofs (limit the need of stuff about Pmult_nat).
- provide nicer names for some lemmas (eg. Pplus_plus instead of
nat_of_P_plus_morphism), compatibility notations provided.
- kill some too-specific lemmas unused in stdlib + contribs
NArith/BinNat:
- N_of_nat, nat_of_N moved from Nnat to here.
- a lemma relating Npred and Nminus
- revised definitions and specification proofs of Npow and Nlog2
NArith/Nnat:
- shorter proofs.
- stuff about Z_of_N is moved to Znat. This way, NArith is
entirely independent from ZArith.
NArith/Ndigits:
- added bitwise operations Nand Nor Ndiff Nshiftl Nshiftr
- revised proofs about Nxor, still using functional bit stream
- use the same approach to prove properties of Nand Nor Ndiff
ZArith/BinInt: huge simplification of Zplus_assoc + cosmetic stuff
ZArith/Zcompare: nicer proofs of ugly things like Zcompare_Zplus_compat
ZArith/Znat: some nicer proofs and names, received stuff about Z_of_N
ZArith/Zmisc: almost empty new, only contain stuff about badly-named
iter. Should be reformed more someday.
ZArith/Zlog_def: Zlog2 is now based on Psize_pos, this factorizes
proofs and avoid slowdown due to adding 1 in Z instead of in positive
Zarith/Zpow_def: Zpower_opt is renamed more modestly Zpower_alt
as long as I dont't know why it's slower on powers of two.
Elsewhere: propagate new names + some nicer proofs
NB: Impact on compatibility is probably non-zero, but should be
really moderate. We'll see on contribs, but a few Require here
and there might be necessary.

Initial patch by Eelis van der Weegen, minor adaptations by myself

Beware! after this, a ./configure must be done. It might also
be a good idea to chase any phantom .vo remaining after a make clean
