gst/switch/gstswitch.*: Add `block' and `switch' signals.

Original commit message from CVS:
2007-12-17  Andy Wingo  <wingo@pobox.com>

* gst/switch/gstswitch.h (struct _GstStreamSelectorClass):
* gst/switch/gstswitch.c (gst_stream_selector_class_init): Add
`block' and `switch' signals.

* gst/switch/Makefile.am:
* gst/switch/gstswitch-marshal.list: Add foo to generate a
marshaller for the `switch' signal. Patch 2/12.
