glib has an base64 implementation, but g_base64_decode() et al. gives no way to detect invalid encodings. All invalid codes are silently ignored. That is not suitable for strictly validating user input. Instead of reimplementing of copy-pasting the code from somewhere, reuse systemd's unbase64mem(). But don't use "hexdecoct.h" directly. Instead, add a single accessor function to our "nm-sd-utils-shared.h" gateway. We want to be careful about which bits from systemd we use, because otherwise re-importing systemd code becomes fragile as you don't know which relevant parts changed.
