"shared/nm-utils" contains general purpose utility functions that only depend on glib (and extend glib with some helper functions). We will also add code that does not use glib, hence it would be good if the part of "shared/nm-utils" that does not depend on glib, could be used by these future projects. Also, we use the term "utils" everywhere. While that covers the purpose and content well, having everything called "nm-something-utils" is not great. Instead, call this "nm-std-aux", inspired by "c-util/c-stdaux".
