Be more flexible in what type of function calls are allowed in `ViaCall ...` actions to be able to include models.
Also get rid of `here here` in traces /o\
As a side-effect, get more precise (=qualified) procedure names in

Summary:
Fix a crash that occurs when subtrahend has an existential variable that
was renamed as in the test.
The crash is due to an assertion in `Sh.exists` that says only variables
in the vocabulary can be existentialy quantifed out.
The problem was `Sh.exists` call in Solver.ml:611. Where `ws`
(existentials of the subthrehend) are not present in the vocabulary of
the remainder. This is because remainder "inheirts" the vocabulary of
the minued.
This fix simply extends the vocabulary of minued with `ws`, which
means the remaainder has the correct vocabulary. This should have no
externally visible effect as `ws` are then existentialed out.
Another option would be to try to change all the `excise_seg` functions,
to keep the vocabulary, but that looked annoying to implement.

* All local variables would get existentially quantified out, that means
the the local variables of the caller couldn't be restored properly
* Frame was added back on after the formals were killed. Which meant

formals would remain to be free variables.

* Previously on return, the actuals wouldn't get added back in, so
their name would be "lost" (that is existentially quantified out),
this patch adds the formals to actuals equalities back on return,
before quantifying the formals out.
* Previously the entry state of the function would be lost if there were
multiple calls to other functions.
