We still link num in `coqc` , that will be removed in a separate step.

IMHO it is a bit more logical, WDYT?
|
|
Add headers to a few files which were missing them.
|
|
Only significant change is in gcd / lcm which now are typed in `Z.t`
|
|
|
|
We also remove trailing whitespace.
Script used:
```bash
for i in `find . -name '*.ml' -or -name '*.mli' -or -name '*.mlg'`; do expand -i "$i" | sponge "$i"; sed -e's/[[:space:]]*$//' -i.bak "$i"; done
```

The changes are large due to `Pervasives` deprecation:
- the `Pervasives` module has been deprecated in favor of `Stdlib`, we
have opted for introducing a few wrapping functions in `Util` and
just unqualified the rest of occurrences. We avoid the shims as in
the previous attempt.
- a bug regarding partial application have been fixed.
- some formatting functions have been deprecated, but previous
versions don't include a replacement, thus the warning has been
disabled.
We may want to clean up things a bit more, in particular
w.r.t. modules once we can move to OCaml 4.07 as the minimum required
version.
Note that there is a clash between 4.08.0 modules `Option` and `Int`
and Coq's ones. It is not clear if we should resolve that clash or
not, see PR #10469 for more discussion.
On the good side, OCaml 4.08.0 does provide a few interesting
functionalities, including nice new warnings useful for devs.

- Simplex based linear prover
Unset Simplex to get Fourier elimination
For lia and nia, do not enumerate but generate cutting planes.
- Better non-linear support
Factorisation of the non-linear pre-processing
Careful handling of equation x=e, x is only eliminated if x is used linearly
- More opaque interfaces
(Linear solvers Simplex and Mfourier are independent)
- Set Dump Arith "file" so that lia,nia calls generate Coq goals
in filexxx.v. Used to collect benchmarks and regressions.
- Rationalise the test-suite
example.v only tests psatz Z
example_nia.v only tests lia, nia
In both files, the tests are in essence the same.
In particular, if a test is solved by psatz but not by nia,
we finish the goal by an explicit Abort.
There are additional tests in example_nia.v which require specific
integer reasoning out of scope of psatz.

We add .mli files, removed dead code and use standard combinators
instead of redefined ad-hoc ones in a few places.
A lot of cleaning still has to be done on this code: documenting the
interfaces, resolving the many abstraction leaks. I suspect there is
still a lot of code duplication.

For the moment, there is an Error module in compilers-lib/ocamlbytecomp.cm(x)a

the new Int module. Only the most obvious were removed, so there
are a lot more in the wild.
This may sound heavyweight, but it has two advantages:
1. Monomorphization is explicit, hence we do not miss particular
optimizations of equality when doing it carelessly with the generic
equality.
2. When we have removed all the generic equalities on integers, we
will be able to write something like "let (=) = ()" to retrieve all
its other uses (mostly faulty) spread throughout the code, statically.
