Thomas Haller 636516e708 logging: make nm-logging.c independent of other core components 
"nm-logging.c" now no longer depends on anything particularly special
from NM core.

* foo ((NMType *) obj);
* // There is no runtime check and passing an invalid pointer

* foo (NM_TYPE (obj));
* // There is a runtime check which prints a g_warning(), but that doesn't
* // avoid the crash as NM_TYPE() cannot do anything then passing on the
* // invalid pointer.
*
* Example 3:
* static void foo (NMType *obj)
* {
* g_return_if_fail (NM_IS_TYPE (obj));

* }
* foo ((NMType *) obj);
* // There is a runtime check which prints a g_critical() which also avoids

* static void foo (NMType *obj)
* {
* g_return_if_fail (NM_IS_TYPE (obj));

* foo (NM_TYPE (obj));

* Example 3 is how it should be done. Type checks in NM_TYPE() are pointless.

* Note that in if the variant type would be invalid, the check still
* wouldn't make the buggy code magically work. Instead of passing a

*
* Also, a function like g_variant_builder_init() already validates

*
* g_return_if_fail (g_variant_type_is_container (type));
*
* So, by having G_VARIANT_TYPE() also validate the type, we validate
* twice, whereas the first validation is rather pointless because it
* doesn't prevent the function to be called with invalid arguments.
*
* Just patch G_VARIANT_TYPE() to perform no check.
