By default Coq stdlib warnings raise an error, so this is really required.

Add headers to a few files which were missing them.

sometimes, to use "intros [= ...]" rather than things like "intros H;
injection H as [= ...]".

Previously, hints added without a specified database where implicitly
put in the "core" database, which was discouraged by the user manual
(because of the lack of modularity of this approach).

See now https://github.com/coq/bignums
Int31 is still in the stdlib.
Some proofs there has be adapted to avoid the need for BigNumPrelude.

There were three versions of injection:
1. "injection term" without "as" clause:
was leaving hypotheses on the goal in reverse order
2. "injection term as ipat", first version:
was introduction hypotheses using ipat in reverse order without
checking that the number of ipat was the size of the injection
(activated with "Unset Injection L2R Pattern Order")
3. "injection term as ipat", second version:
was introduction hypotheses using ipat in left-to-right order
checking that the number of ipat was the size of the injection
and clearing the injecting term by default if an hypothesis
(activated with "Set Injection L2R Pattern Order", default one from 8.5)
There is now:
4. "injection term" without "as" clause, new version:
introducing the components of the injection in the context in
left-to-right order using default intro-patterns "?"
and clearing the injecting term by default if an hypothesis
(activated with "Set Structural Injection")
The new versions 3. and 4. are the "expected" ones in the sense that
they have the following good properties:
- introduction in the context is in the natural left-to-right order
- "injection" behaves the same with and without "as", always
introducing the hypotheses in the goal what corresponds to the
natural expectation as the changes I made in the proof scripts for
adaptation confirm
- clear the "injection" hypothesis when an hypothesis which is the
natural expectation as the changes I made in the proof scripts for
adaptation confirm
The compatibility can be preserved by "Unset Structural Injection" or
by calling "simple injection".
The flag is currently off.

+ consequences of this check on the standard library (moved the no-op
in Notation modifiers to what there were supposed to do; these are
anyway local notations, so compatibility is safe - please AS or PL,
amend if needed).

in Prop of constructors of inductive types independent of these names.
Incidentally upgraded/simplified a couple of proofs, mainly in Reals.
This prepares to the next commit about using names based on H for such
hypotheses in Prop.

- For instance, refl_equal --> eq_refl
- Npos, Zpos, Zneg now admit more uniform qualified aliases
N.pos, Z.pos, Z.neg.
- A new module BinInt.Pos2Z with results about injections from
positive to Z
- A result about Z.pow pushed in the generic layer
- Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l}
- Using tactic Z.le_elim instead of Zle_lt_or_eq
- Some cleanup in ring, field, micromega
(use of "Equivalence", "Proper" ...)
- Some adaptions in QArith (for instance changed Qpower.Qpower_decomp)
- In ZMake and ZMake, functor parameters are now named NN and ZZ
instead of N and Z for avoiding confusions

In particular, we merge the old Zdivide (used to be an ad-hoc
inductive predicate) and the new Z.divide (based on exists).
Notations allow to do that (almost) transparently, the only
impact is that the name picked by the system will not be "q"
anymore when destructing a Z.divide. Some fragile scripts
may have to be fixed.

As for power recently, we add a specification in NZ,N,Z,
derived properties, implementations for nat, N, Z, BigN, BigZ.
- For nat, this sqrt is brand new :-), cf NPeano.v
- For Z, we rework what was in Zsqrt: same algorithm,
no more refine but a pure function, based now on a sqrt
for positive, from which we derive a Nsqrt and a Zsqrt.
For the moment, the old Zsqrt.v file is kept as Zsqrt_compat.v.
It is not loaded by default by Require ZArith.
New definitions are now in Psqrt.v, Zsqrt_def.v and Nsqrt_def.v
- For BigN, BigZ, we changed the specifications to refer to Zsqrt
instead of using characteristic inequations.
On the way, many extensions, in particular BinPos (lemmas about order),
NZMulOrder (results about squares)

- 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

- Records of operations and specs in CyclicAxioms are now
type classes (under a module ZnZ for qualification).
We benefit from inference and from generic names:
(ZnZ.mul x y) instead of (znz_mul (some_ops...) x y).
- Beware of typeclasses unfolds: the line about
Typeclasses Opaque w1 w2 ... is critical for decent
compilation time (x2.5 without it).
- Functions defined via same_level are now obtained from a
generic version by (Eval ... in ...) during definition.
The code obtained this way should be just as before, apart
from some (minor?) details. Proofs for these functions
are _way_ simplier and lighter.
- The macro-generated NMake_gen.v contains only generic iterators
and compare, mul, div_gt, mod_gt. I hope to be able to adapt
these functions as well soon.
- Spec of comparison is now fully done with respect to Zcompare
- A log2 function has been added.
- No more unsafe_shiftr, we detect the underflow directly with sub_c

- No more nesting of Module and Module Type, we rather use Include.
- Instead of in-name-qualification like NZeq, we use uniform
short names + modular qualification like N.eq when necessary.
- Many simplification of proofs, by some autorewrite for instance
- In NZOrder, we instantiate an "order" tactic.
- Some requirements in NZAxioms were superfluous: compatibility
of le, min and max could be derived from the rest.
- NMul removed, since it was containing only an ad-hoc result for
ZNatPairs, that we've inlined in the proof of mul_wd there.
- Zdomain removed (was already not compiled), idea of a module
with eq and eqb reused in DecidableType.BooleanEqualityType.
- ZBinDefs don't contain any definition now, migrate it to ZBinary.

Mostly results about Zgcd (commutativity, associativity, ...).
Slight improvement of ZMicromega.
Beware: some lemmas of Zdiv/ Znumtheory were asking for
too strict or useless hypothesis. Some minor glitches may occur.
By the way, some iff lemmas about negb in Bool.v

now dumb wrappers around Zsqrt_plain. Wanted (dead or alive): better
implemntations _and_ their proofs.

This isn't useful for BigN et BigZ, but it can't hurt; and moreover
it's a simple way to understand CyclicAxioms. Next step: proving that
Int31 is also an implementation of CyclicAxiom.
