* gst/switch/gstswitch.h (struct _GstStreamSelector):

* gst/switch/gstswitch.c (gst_stream_selector_wait)
(gst_selector_pad_chain, gst_stream_selector_init)
(gst_stream_selector_dispose): Add infrastructure for new blocking
mechanism that does not use gst_pad_set_blocked, which does not
work on sink pads. Patch 7/12.
