trace: use glib atomic int types
Juan reported that RHEL 6.4 hosts give compiler warnings because we use unsigned int while glib prototypes use volatile gint in trace/simple.c. trace/simple.c:223: error: pointer targets in passing argument 1 of 'g_atomic_int_compare_and_exchange' differ in signedness These variables are only accessed with glib atomic int functions so let's play it by the book and use volatile gint.
