NMParamSpecSpecialized existed basically to provide a version of GParamSpecBoxed that could compare dbus-glib-valued properties correctly. However, g_param_values_cmp() was only used by NM directly in one place (NMSetting's compare_property()), and we don't actually need to indirect through GParamSpec there; we could just call NMParamSpecSpecialized's value-comparison function directly. So, change all NMParamSpecSpecialized properties to GParamSpecBoxed, rename the _gvalues_compare() function it used to "nm_property_compare()", and use that from NMSetting. (g_param_values_cmp() also gets used internally by g_param_value_defaults(), but all NMParamSpecSpecialized properties have a default value of NULL, so GParamSpecBoxed's pointer-equality check will do the job just fine there.)
