8a913981f6 fix #6813 - proofs terms are fragile with respect to simplificiation of not(not(e)). It would be better if proof terms didn't have to track this level of detail, but the legacy proof format assumes strictly checkable proofs. A patch is to fixup terms within the mk_transitivity constructor

939bf1c725 wip - alpha support for polymorphism 
An initial update to support polymorphism from SMTLIB3 and the API (so far C, Python).

The WIP SMTLIB3 format is assumed to be supporting the following declaration

```
(declare-type-var A)
```
Whenever A is used in a type signature of a function/constant or bound quantified variable, it is taken to mean that all instantiations of A are included in the signature and assertions.
For example, if the function f is declared with signature A -> A, then there is a version of f for all instances of A.
The semantics of polymorphism appears to follow previous proposals: the instances are effectively different functions.
This may clash with some other notions, such as the type signature forall 'a . 'a -> 'a would be inhabited by a unique function (the identity), while this is not enforced in this version (and hopefully never because it is more busy work).

The C API has the function 'Z3_mk_type_variable' to create a type variable and applying functions modulo polymorphic type signatures is possible.
The kind Z3_TYPE_VAR is added to sort discriminators.

This version is considered as early alpha. It passes a first rudimentary unit test involving quantified axioms, declare-fun, define-fun, and define-fun-rec.
