Update .po files
Release 1.2.3
playbin: Fix memory leak in unit test
playbin: Only put parsers and sinks first, not all non-decoders

https://bugzilla.gnome.org/show_bug.cgi?id=722316
playbin: Insert decoders without GstAVElement information between the other decoders

Otherwise they would be preferred over all decoders independent
of their ranks.

playbin: Fix memory leak in autoplugging code

We should not leak element factories ideally.
playbin: First try to get the pad's current caps, then query caps

The caps query might give us ANY caps while the pad has fixed caps
configured currently.
playsink: Only remove the complete text chain if the text pad goes away

If the text pads does not go away we just set the overlay to silent, which
allows us to immediately re-enable subs later again. However before this
change we also released the streamsynchronizer text pads, which deadlocked
because there was still dataflow going on. Just do this only if we remove
the complete chain.

playbin: Keep inputselector around until we release its pads

Otherwise there's an interesting race condition when we destroy
the inputselector (actually it will be destroyed later when its state
change message gets destroyed) and afterwards release its sinkpad.

This is the code path when the last channel is removed from the
input selector.

Gave this warning sometimes, for chained oggs or whenever else
we change decode groups:
GStreamer-CRITICAL **: Padname '':sink_0 does not belong to element inputselector0 when removing
oggdemux: allow file to go until the end in push mode

When seeking back to original state after duration seeks, let
upstream know that we want the whole file, including the last
byte that wasn't requested on the duration seeks.
