gpg,sm: Merge the two versions of check_special_filename.
* sm/gpgsm.c (check_special_filename): Move to .. * common/sysutils.c (check_special_filename): here. Add arg NOTRANSLATE. (allow_special_filenames): New local var. (enable_special_filenames): New public functions. * sm/gpgsm.c (allow_special_filenames): Remove var. (main): Call enable_special_filenames instead of setting the var. (open_read, open_es_fread, open_es_fwrite): Call check_special_filename with 0 for NOTRANSLATE. * common/iobuf.c (special_names_enabled): Remove var. (iobuf_enable_special_filenames): Remove func. (check_special_filename): Remove func. (iobuf_is_pipe_filename): Call new version of the function with NOTRANSLATE set. (do_open): Ditto. * g10/gpg.c (main): Call enable_special_filenames instead of iobuf_enable_special_filenames. * g10/gpgv.c (main): Ditto.
Note that we keep the iobuf.c:translate_file_handle because it is a
bit different (for whatever reasons) than the translate function from
sysutils.
