To enable the usage of the with statement for the Solver class
instances, this commit adds __enter__ and __exit__ methods.
The with statement should offer a more concise and safer
alternative to explicit usage of push() and pop() methods.
`FindPythonInterp` has been deprecated for a long time and is more
verbal about that deprecation now.
The build system no longer uses `PYTHON_EXECUTABLE` but instead uses
`Python3_EXECUTABLE`.
The bulk of the functionality using these was removed between
Z3 4.4.1 and 4.5.0, back in 2015.

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.
* implement Optimize class for the high level Typescript API
* javascript and wasm: add _malloc to exported functions
fix the bug https://github.com/Z3Prover/z3/issues/6709
* javascript: add tests for the Optimize class
* javascript: no reason that minimize and optimize must be constants
Hello, I was looking at the different api string conversions for FuncEntry and I believe that the ml version is incorrect? Clearly we want the argument(`c`) to be comma separated from the accumulated string `p`. The current implementation just so happens to have most of the arguments separated, but the order is flipped and one of the commas is misplaced.
