Moved the typedef to backend.h.

2000-11-26  Martin Baulig  <martin@home-of-linux.org>

	* include/glibtop/call-vector.h (glibtop_call_vector): Moved
	the typedef to backend.h.

	* include/glibtop/backend.h (glibtop_open_backend_l): Renamed
	to glibtop_open_backend(), removed the `glibtop_client *'
	argument and made the `GError *' argument non-optional.

	* include/glibtop/glibtop-client.h
	(glibtop_client_add_backend, glibtop_client_remove_backend): New
	functions to add/remove a glibtop_backend to a glibtop_client.
	(glibtop_client_open_backend): New convenient function; calls
	glibtop_open_backend() and glibtop_client_add_backend().
