Subject: [PATCH] plugins/elements/gstinputselector.c: Reuse the
 get_linked_pads for both source and sinkpads because they are the same.

Original commit message from CVS:
* plugins/elements/gstinputselector.c: (gst_input_selector_init),
(gst_input_selector_event), (gst_input_selector_query):
Reuse the get_linked_pads for both source and sinkpads because they are
the same.
Implement a custum event handler and get the internally linked pad
directly instead of relying on the default (slower) implementation.
