Add LaxComma to categories.v

I had forgotten to export it when I originally ported it.

Add LaxComma to categories.v
Work around bugs 3773 and (probably) 3772

These are https://coq.inria.fr/bugs/show_bug.cgi?id=3773, open_constr no
longer does typeclass resolution, sometime within the past month, and
https://coq.inria.fr/bugs/show_bug.cgi?id=3772, [rewrite] is
inconsistent about unfolding and evar instantiation.

If we're actually going to merge this, we might want to put `simpl
rewrite` back to using `constr`, and make `simpl erewrite` variants that
use `open_constr` and `erewrite`.
Work around bug 3848

This is https://coq.inria.fr/bugs/show_bug.cgi?id=3848, [refine]
sometimes incorrectly leaves over trivially solvable typeclass goals.
work around bug 3811 in extendable_const_isconnected_inO
Work around bug 3854

This is https://coq.inria.fr/bugs/show_bug.cgi?id=3854, Typeclass
resolution fails where it used to succeed (change in the order of
unification in [refine] or in the order of canonical structure
resolution?)
dummy universe parameter for O_ind_internal, needed by Nullification
Work around bug(?) 3703

This is https://coq.inria.fr/bugs/show_bug.cgi?id=3703, [rewrite] with
Keyed Unification fails to unfold some things that [rewrite] with
unkeyed unification unfolds

N.B. This commit does not compile with the pinned version of Coq.  In a
few commits, we'll bump the submodule.
Set Keyed Unification and bump Coq submodule

Bumping the submodule gives us some keyed unification, primitive
projection, and universe polymorphism fixes.

This closes #531 and #557 and #593.

The comment on the [Set Keyed Unification] directive was written by Mike
Shulman.

Note that we get a host of errors if we bump the submodule without
setting keyed unification; the current version of Coq doesn't attempt to
make [rewrite] work correctly in the presence of primitive projections
without [Set Keyed Unification].

A few files got slightly slower, but I think this is an acceptable diff
stat.

O_ind_internal, needed by Nullification" compile with the pinned version
of Coq.
