Add the ability to declare [Hint Extern]'s with no pattern.
This permits to create a database [relations] in [RelationClasses] with
a single extern tactic in it that tries to apply [reflexivity] or
[symmetry]. This is then automatically used in [auto with *] and repair
backward compatibility. The previous commit broke some scripts which were
using [intuition] to do (setoid) [reflexivity] or [symmetry]: this
worked only by accident, because the hint database of typeclasses was
used. Overrall, this also allows to put a bunch of
always-applicable, related tactics in some database or to use
[Hint Extern] but match only on hypotheses.
