Update bindings for Z3 4.8.6

[waywardmonkeys]

The exported functions from the C API have changed:

+    pub fn Z3_mk_set_has_size(c: Z3_context, set: Z3_ast, k: Z3_ast) -> Z3_ast;
+    pub fn Z3_get_seq_sort_basis(c: Z3_context, s: Z3_sort) -> Z3_sort;
+    pub fn Z3_get_re_sort_basis(c: Z3_context, s: Z3_sort) -> Z3_sort;
+    pub fn Z3_mk_lstring(c: Z3_context, len: ::std::os::raw::c_uint, s: Z3_string) -> Z3_ast;
+    pub fn Z3_get_lstring(
+    pub fn Z3_mk_str_lt(c: Z3_context, prefix: Z3_ast, s: Z3_ast) -> Z3_ast;
+    pub fn Z3_mk_str_le(c: Z3_context, prefix: Z3_ast, s: Z3_ast) -> Z3_ast;

I just tried to get set up with a project that relied on this one. But the z3 get model code was always returning 0s. I think it is because when I ran sudo apt get install libz3-dev I got a 4.x version.

a. As someone that has never used Z3 before, How can I help get this project compatible with new versions? b. As someone that is not very experienced with ubuntu, How can I get a compatible version of z3 set up? c. How can we change the build script so we get the error at build time instead of runtime?

I'm running z3 4.8.10; looks like this has been resolved.
