core: add nm_utils_cmp_connection_by_autoconnect_priority_p_with_data() function

Browse source 
Have a proper cmp() function and a wrapper *_p_with_data() that can be
used for g_qsort_with_data().

Thus, establish a naming scheme (*_p_with_data()) for these compare
wrappers that we need all over the place. Note, we also have
nm_strcmp_p_with_data() for the same reason and later more such
functions will follow.
