Currently, `.v` under the `Coq.` prefix are found in both `theories`
and `plugins`. Usually these two directories are merged by special
loadpath code that allows double-binding of the prefix.
This adds some complexity to the build and loadpath system; and in
particular, it prevents from handling the `Coq.*` prefix in the
simple, `-R theories Coq` standard way.
We thus move all `.v` files to theories, leaving `plugins` as an
OCaml-only directory, and modify accordingly the loadpath / build
infrastructure.
Note that in general `plugins/foo/Foo.v` was not self-contained, in
the sense that it depended on files in `theories` and files in
`theories` depended on it; moreover, Coq saw all these files as
belonging to the same namespace so it didn't really care where they
lived.
This could also imply a performance gain as we now effectively
traverse less directories when locating a library.

Add missing zify class instances for `Pos.pred_double`, `Pos.pred_N`,
`Pos.of_nat`, `Pos.add_carry`, `Pos.pow`, `Pos.square`, `Z.pow`, `Z.double`,
`Z.pred_double`, `Z.succ_double`, `Z.square`, `Z.div2`, `Z.quot2`, `isZero`, and
`isLeZero`. Instances for `isZero` and `isLeZero` are useful to provide new
zify instances by using Micromega tactics.

- Fix reification of overloaded operators
(triggers convertibility checks with existing terms)
- Zify instances need not be in hnf
- Fix specification of bool operators
- Add (limited) support for comparison
fixes #10779

The logic is implemented in OCaml. By induction over the terms,
guided by registered Coq terms in ZifyInst.v, it generates a rewriting
lemma. The rewriting is only performed if there is some progress. If
the rewriting fails (due to dependencies), a novel hypothesis is
generated.
This PR fixes #5155, fixes #8898, fixes #7886, fixes #10707, fixes #9848
ans fixes #10755.
The zify plugin is placed in the micromega directory.
(Though the reason is unclear, having it in a separate directory is
bad for efficiency.) efficiency impact.
There are also a few improvements of lia/lra that are piggybacked.
- more aggressive pruning of useless hypotheses
- slightly optimised conjunctive normal form
- applies exfalso if conclusion is not in Prop
- removal of Timeout in test-suite
