Pretty-printer infrastructure created (in src/printer) and SMT-LIBv2 printer
implemented. This new infrastructure removes support for pretty-printing
(even in the AST language) an Expr with reference count 0. Previously,
this was supported in a few places internally to the expr package, for
example in NodeBuilder. (Now, a NodeBuilder cannot be prettyprinted, you
must extract the Node before printing it.)
