For better or worse, we already pull in large parts of systemd sources. I need a base64 decode implementation (because glib's g_base64_decode() cannot reject invalid encodings). Instead of coming up with my own or copy-paste if from somewhere, reuse systemd's unbase64mem(). But for that, make systemd's basic bits an independent static library first because I will need it in libnm-core. This doesn't really change anything except making "libnm-systemd-core.la" an indpendent static library that could be used from "libnm-core". We shall still be mindful about which internal code of systemd we use, and only access functionality that is exposed via "systemd/nm-sd-utils-shared.h".
