Rename:
write_c_string -> write_cistring
build_intstring -> build_istring
build_string -> build_cistring
build_ext_string -> build_extstring
make_ext_string -> 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.
