libs/gst/base/gstbasesink.c: Store the sync time of the buffer end position separatly in a new variable eos_rtime so ...

Browse source 
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_get_sync_times),
(gst_base_sink_do_sync), (gst_base_sink_chain_unlocked),
(gst_base_sink_get_position), (gst_base_sink_change_state):
Store the sync time of the buffer end position separatly in a
new variable eos_rtime so we can properly sync the EOS event.
Fixes #340697.
Fix the docs for gst_base_sink_set_qos_enabled().
Don't set segment start to invalid value when we receive a
non TIME newsegment.
get closer to handling position reporting for negative rates
correctly.
