Niels Möller b7239a9dc8 Make rtc_base/refcount.h self contained, not including refcountedobject.h.
The refcount.h file doesn't depend on anything from
refcountedobject.h. The motivation of this change to make it possible
to add additional declarations to refcount.h, and include it from
refcountedobject.h.
