format+gadts: make format types "relational" to fix %(...%) typing
...
See the long comment in pervasives.ml for an explanation of the
change. The short summary is that we need to prove more elaborate
properties between the format types involved in the typing of %(...%),
and that proving things by writing GADT functions in OCaml reveals
that Coq's Ltac is a miracle of usability.
Proofs on OCaml GADTs are runtime functions that do have a runtime
semantics: it is legitimate to hope that those proof computations are
as simple as possible, but the current implementation was optimized
for feasability, not simplicity. François Bobot has some interesting
suggestions to simplify the reasoning part (with more equality
reasoning where I used transitivity and symmetry of the
relation profusely), which may make the code simpler in the future
(and possibly more efficient: the hope is that only %(...%) users will
pay a proof-related cost).

Use a nominal datatype for CamlinternalFormat.format6
...
This should make the type-checking of formats simpler and more robust:
instead of trying to find a pair as previously, we can now use the
path of the format6 type directly.
A nice side-effect of the change is that the internal definition of
formats (as a pair) is not printed in error messages anymore.
Because format6 is in fact defined in the CamlinternalFormatBasics
submodule of Pervasives, and has an alias at the toplevel of
Pervasives, error messages still expand the definition:
> Error: This expression has type
> ('a, 'b, 'c, 'd, 'd, 'a) format6 =
> ('a, 'b, 'c, 'd, 'd, 'a) CamlinternalFormatBasics.format6
> but an expression was expected of type ...
Passing the option `-short-paths` does avoid this expansion and
returns exactly the same error message as 4.01:
> Error: This expression has type ('a, 'b, 'c, 'd, 'd, 'a) format6
> but an expression was expected of type ...
(To get this error message without -short-paths, one would need to
define format6 directly in Pervasives; but this type is mutually
recursive with several GADT types that we don't want to add in the
Pervasives namespace unqualified. This is why I'll keep the alias
for now.)
