more general.

of Zdiv
Some details:
- ZAux.v is the only file left in Ints/Z. The few elements that remain in it
are rather specific or compatibility oriented. Others parts and files have
been either deleted when unused or pushed into some place of ZArith.
- Ints/List/ is removed since it was not needed anymore
- Ints/Tactic.v disappear: some of its tactic were unused, some already in
Tactics.v (case_eq, f_equal instead of eq_tac), and the nice contradict
has been added to Tactics.v
- Znumtheory inherits lots of results about Zdivide, rel_prime, prime, Zgcd, ...
- A new file Zpow_facts inherits lots of results about Zpower. Placing them
into Zpower would have been difficult with respect to compatibility
(import of ring)
- A few things added to Zmax, Zabs, Znat, Zsqrt, Zeven, Zorder
- Adequate adaptations to Ints/num/* (mainly renaming of lemmas)
Now, concerning Zdiv, the behavior when dividing by a negative number is now
fully proved. When this was possible, existing lemmas has been extended,
either from strictly positive to non-zero divisor, or even to arbitrary
divisor (especially when playing with Zmod). These extended lemmas are named
with the suffix _full, whereas the original restrictive lemmas are retained
for compatibility. Several lemmas now have shorter proofs (based on unicity
lemmas). Lemmas are now more or less organized by themes (division and order,
division and usual operations, etc). Three possible choices of spec for
divisions on negative numbers are presented: this Zdiv, the ocaml approach
and the remainder-always-positive approach. The ugly behavior of Zopp
with the current choice of Zdiv/Zmod is now fully covered. A embryo of
division "a la Ocaml" is given: Odiv and Omod.

H: forall (n:nat)(b:bool), P n b
then "narrow H with 0 true" will leave H: P 0 true.
The name for this tactic should ideally be "specialize", but this one
already exists (old stuff, same idea but no "in place" modification,
not documented anymore, still used in users contribs).

Added a tactic "now" which is nonrecursive but generalizes "trivial".

(apply -> H, etc.), which prevented Coq compilation.
These tactics require an extension of syntax: t1; [t2 | .. ],
which has to be submitted first.

"apply -> t", "apply <- t", "apply -> t in H" and "apply <- t in H" .
Also added the tactic false_hyp based on absurd_hyp.
