This turns gdbpy_ref into a template class, so that it can be used to wrap subclasses of PyObject. The default argument remains PyObject; and this necessitated renaming uses of "gdbpy_ref" to "gdbpy_ref<>". gdb/ChangeLog 2017-02-10 Tom Tromey <tom@tromey.com> * python/py-ref.h (gdbpy_ref_policy): Now a template. (gdbpy_ref): Now a template; allow subclasses of PyObject to be used. * python/py-arch.c, python/py-bpevent.c, python/py-breakpoint.c, python/py-cmd.c, python/py-continueevent.c, python/py-event.c, python/py-exitedevent.c, python/py-finishbreakpoint.c, python/py-framefilter.c, python/py-function.c, python/py-inferior.c, python/py-infevents.c, python/py-linetable.c, python/py-newobjfileevent.c, python/py-param.c, python/py-prettyprint.c, python/py-ref.h, python/py-signalevent.c, python/py-stopevent.c, python/py-symbol.c, python/py-threadevent.c, python/py-type.c, python/py-unwind.c, python/py-utils.c, python/py-value.c, python/py-varobj.c, python/py-xmethods.c, python/python.c, varobj.c: Change gdbpy_ref to gdbpy_ref<>.
