* options.h, export.c (do_export_stream), keyedit.c (keyedit_menu, 

menu_clean_subkeys_from_key), trustdb.h, trustdb.c
(clean_subkeys_from_key): Remove subkey cleaning function.  It is of
very limited usefulness since it cannot be used on any subkey that can
sign, and can only affect multiple selfsigs on encryption-only
subkeys.
