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.
