Share more information between constructors and arity of an inductive
type in order to solve implicit arguments.

Declaration of multiple hypotheses or parameters now share typing
information for inference of implicit arguments.

Protection against "Bad recursive type" in w_unify0 (bug #3036).

Morally, unification wants to unify "fun x:Meta => Meta"
with "fun x:nat => match x with ... end". Retyping is asked to
type "match x with ... end" in the context "x:Meta" where the
type of x has de facto been lost. Retyping fails.

I don't see an easy remedy since w_unify0 builds the unifier
lazily, and I'm not sure it is worth to propagate the unifier to
retyping so that it knows it. After all, the call to retyping in
w_unify0 is not so critical.

it into the standard logger instead.

Xml_datatype.mli ships the xml type

This breaks the dependency of Xml_parser, Xml_printer and Xml_utils
on Serialize.
