Refactor mkoptions (#1631)

This commit refactors code generation for options. It uses a new configuration format for defining options (*.toml) and a new Python script mkoptions.py to generate the source code and option documentation.

The option behavior did not change for most of the options, except that for bool --enable-/--disable- long options enable/disable was removed. E.g. --enable-miplib-trick and --disable-miplib-trick got changed to --miplib-trick and --no-miplib-trick.

This commit fixes also an issues with set-option/get-option via the SMT2 interface. Before long options were only accessible if the name included the =ARG part.

+.SH NAME
+libcvc4 \- a library interface for the CVC4 theorem prover
+.SH SYNOPSIS
+
+A small program like:

+#include <iostream>
+#include "expr/expr_manager.h"
+#include "smt/smt_engine.h"
+
+using namespace CVC4;
+
+int main() {
+  ExprManager em;
+  SmtEngine smt(&em);
+  Expr onePlusTwo = em.mkExpr(kind::PLUS,
+                              em.mkConst(Rational(1)),
+                              em.mkConst(Rational(2)));
+  std::cout << language::SetLanguage(language::output::LANG_CVC4)
+            << smt.getInfo("name")
+            << " says that 1 + 2 = "
+            << smt.simplify(onePlusTwo)

+.SH DESCRIPTION
+
+The main classes of interest in CVC4's API are
+.I ExprManager,
+.I SmtEngine,
+and a few related ones like
+.I Expr
+and
+.I Type.
+
+The
+.I ExprManager
+is used to build up expressions and types, and the
+.I SmtEngine
+is used primarily to make assertions, check satisfiability/validity, and extract models and proofs.
