glib-aux: fix atomic pattern in nm_ref_string_unref() 
It's simply not valid to read the ref-count without an atomic.
The compiler might optimize out the assignment to "r" and read the
_ref_count field multiple times. Thereby, we might at first appear
to be larger than > 1, and later pass 1 to compare-and-exchange.

We need an atomic get here.

Fixes: 19d4027824 ('refstr: inline nm_ref_string_{ref,unref}()')

libnm-glib-aux

A static helper library with general purpose helpers on top of glib.

This is similar to libnm-std-aux (on which this library depends). The difference is that libnm-std-aux only requires standard C (C11), while this has a dependency on glib.

As this has no additional dependencies, we should have all our glib code use this internal helper library. It contains helpers that should be available (and used) in all our C/glib applications/libraries.

Parts of this library are usually already included via the nm-default*.h headers.
