(setup_coding_system): Fix setting up

coding->spec.ccl.valid_codes for CCL based coding system.
(code_convert_region): Set point to FROM before inserting the
result of pre-write-funciton.  Preserve original point.
(code_convert_string): If coding->type is coding_type_ccl, do
conversion even if the length of conversion region is zero.
