check/gst/gstbin.c: An extra refcount is taken in basesrc.

Browse source 
Original commit message from CVS:
* check/gst/gstbin.c: (GST_START_TEST):
An extra refcount is taken in basesrc.

* gst/base/gstbasesrc.c: (gst_base_src_init), (gst_base_src_query),
(gst_base_src_get_range), (gst_base_src_pad_get_range),
(gst_base_src_loop):
Small cleanups, check for flushing after being unlocked from the
LIVE_LOCK. take refcounts correctly (not yet everywhere).
Don't send out EOS when going to READY.
