New functions in the glib introspection data

There are various functions that appeared in the introspection data recently and I am curious about some of them

• g_resolver_record_type_to_rrtype / g_resolver_records_from_res_query-> supposedly should be private and is needed only for some test
• g_trace_define_int64_counter / g_trace_mark / g_trace_set_int64_counter private functions that ends up there somehow being pulled in the introspection data
• Should g_slice_debug_tree_statistics be exposed in introspection data? it seems to be useful to run with gdb but not really useful for bindings
