+These files are either copied from NetworkManager or just empty files. The
+files live in the nn-utils subdirectory as that makes the relative

+
+The test-networkmanager-service.py is also from NetworkManager. It is
+however extended for our use here.

+ * Example 3:
+ *     static void foo (NMType *obj)

+ * The boolean type _Bool is C99 while we mostly stick to C89. However, _Bool is too
+ * convinient to miss and is effectively available in gcc and clang. So, just use it.
+ *
+ * Usually, one would include "stdbool.h" to get the "bool" define which aliases
+ * _Bool. We provide this define here, because we want to make use of it anywhere.
+ * (also, stdbool.h is again C99).
+ *
+ * Using _Bool has advantages over gboolean:
+ *
+ * - commonly _Bool is one byte large, instead of gboolean's 4 bytes (because gboolean
+ *   is a typedef for gint). Especially when having boolean fields in a struct, we can
+ *   thereby easily save some space.
+ *
+ * - _Bool type guarantees that two "true" expressions compare equal. E.g. the follwing
+ *   will not work:
+ *        gboolean v1 = 1;
+ *        gboolean v2 = 2;
+ *        g_assert_cmpint (v1, ==, v2); // will fail
+ *   For that, we often to use !! to coerce gboolean values to 0 or 1:
+ *        g_assert_cmpint (!!v2, ==, TRUE);
+ *   With _Bool type, this will be handled properly by the compiler.
+ *
+ * - For structs, we might want to safe even more space and use bitfields:
+ *       struct s1 {
+ *           gboolean v1:1;
+ *       };
+ *   But the problem here is that gboolean is signed, so that
+ *   v1 will be either 0 or -1 (not 1, TRUE). Thus, the following
+ *   fails:
+ *      struct s1 s = { .v1 = TRUE, };
+ *      g_assert_cmpint (s1.v1, ==, TRUE);
+ *   It will however work just fine with bool/_Bool while retaining the
+ *   notion of having a boolean value.
+ *
+ * Also, add the defines for "true" and "false". Those are nicely highlighted by the editor
+ * as special types, contrary to glib's "TRUE"/"FALSE".
