Don't use snprintf(), but use sprintf instead and do our own length calculations, because glibc may complain about us passing %n in a format string if the string is in writable memory, and here the format string is always in writable memory since we construct it on the fly. This happens if glibc has been compiled with _FORTIFY_SOURCE=2, which seems to be the case on some distros/systems). On the upside, we now use the sprintf code path on all systems which should be better from a maintenance point of view. https://bugzilla.gnome.org/show_bug.cgi?id=697970
