configure.ac: Adding examples/switch/Makefile
Original commit message from CVS: 2004-01-11 Julien MOUTTE <julien@moutte.net> * configure.ac: Adding examples/switch/Makefile * examples/Makefile.am: Adding examples/switch * examples/switch/Makefile.am: Adding switcher example. * examples/switch/switcher.c: (got_eos), (idle_iterate), (switch_timer), (main): Adding an example demonstrating switch usage with 2 videotestsrc showing different patterns. * gst/switch/gstswitch.c: (gst_switch_request_new_pad), (gst_switch_init): Fixing switch with the new caps system.
