[libvirt] [libvirt-glib] Add annotations for gvir_stream_add_watch{_full}

[Christophe Fergeau]

This should silence this compile warning:
  GEN    LibvirtGObject-1.0.gir
libvirt-gobject-stream.c:603: Warning: LibvirtGObject:
gvir_stream_add_watch: argument func: Missing (scope) annotation for
callback without GDestroyNotify (valid: call, async)

This also adds API documentation for these functions.
