stdlib: Generalize erl_parse:abstract/2
The 'encoding' option of erl_parse:abstract/2 has been extended to include 'none' and a callback function (a predicate). The rationale is that a more general means of determining what integer lists are to be represented as strings may help readability when generating Erlang code given input in some other encoding than Latin-1 or UTF-8.
