all: use _NM_G_TYPE_CHECK_INSTANCE_CAST() for internal uses 
G_TYPE_CHECK_INSTANCE_CAST() can trigger a "-Wcast-align":

Avoid that by using _NM_G_TYPE_CHECK_INSTANCE_CAST().

This can only be done for our internal usages. The public headers
of libnm are not changed.

libnm-std-aux

A static helper library with general purpose helpers on top of standard C (C11).

As this has no additional dependencies, we should have all our C code use this internal helper library. It contains helpers that should be available (and used) everywhere where we write C.

Our C is gnu11, that is C11 or newer with some GCC-ism. The requirement is that it is supported by all complilers we care about (in pratice GCC and Clang).

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