"While 'atomic' has a volatile qualifier, this is a historical artifact and the pointer passed to it should not be volatile." Furthermore "It is very important that all accesses to a particular integer or pointer be performed using only this API" (from https://developer.gnome.org/glib/2.68/glib-Atomic-Operations.html) Hence initialization of atomic variables is changed to also use this API, instead of directly initializing the value. This also fixes a few cases where atomic variables were accessed directly. see also libs/pbd/pbd/g_atomic_compat.h
