make_extstring buffer_insert_c_string -> buffer_insert_ascstring intern_int -> intern_istring These functions have been renamed so that the naming harmonizes with the typedefs for strings: `cistring' along with CIbyte *, `istring' along with Ibyte *, `extstring' along with Extbyte *, `ascstring' along with Ascbyte *. Also make buffer_insert_ascstring take Ascbyte * and assert that its argument is ASCII.
