6718f0cfff videodecoder: misc improvements/changes
Use g_list_free_full instead of walking lists twice when freeing
them.

Remove pointless clause in gst_video_decoder_chain that doesn't
actually have any effect.

Other changes to make the code slightly more like the 0.11
version.

ffd0f28460 videodecoder: Improve timestamp handling.
Fix problems with timestamp calculations when the incoming
buffers have sparse timestamps (as for theora) and reverse
playback. Fixes #675773

1935cf0022 videodecoder: Re-work reverse playback handling
Move processing of the gather list into the flush_parse function.

Add a last ditch attempt to apply timestamps to outgoing buffers
when walking backwards through decoded frames. Requires that each
gathered region has at least one timestamp.

Make sure to remove decoded packets from the decode list when
they are sent - otherwise the list just grows on each cycle, with
more and more frames being decoded and then clipped away.

Break out of the processing loop early on a bad flow return to make
seeking more responsive.

Use the gst_video_decoder_clip_and_push_buf function in reverse
mode, instead of pushing all buffers arbitrarily.

A couple of small efficiency gains in the list handling, by moving
list elements directly and not reallocating, and by reversing
and concatenating the gather list instead of moving it one node
at a time.

Rename the gst_video_decoder_do_finish_frame function to
gst_video_decoder_release_frame.

2d770ac406 videodecoder: Rename gst_video_decoder_have_frame_2 function
Rename gst_video_decoder_have_frame_2 to
gst_video_decoder_decode_frame and pass the frame to process
directly, rather than using the current_frame pointer as a holding
pen.

Move the negative rate handling out of the function to where it
is needed, and remove the process flag.

4b946e8cee videodecoder: Ensure buffers don't disappear early
The frames are the owners of the buffers. In cases where a decoder
would keep around reference frames, we need to ensure they don't
disappear early.
To handle this, we pass downstream a complete sub-buffer of the output
buffer, ensuring that the buffer will only be released when downstream
is done with it *AND* the frame is no longer used.

492341db77 oggdemux: fix quadratic search for last page
A crafted file with invalid pages will cause repeated searches from
earlier offsets in steps of 8500 bytes, but reading till the end of
the stream. Since we know the maximum size of an Ogg page, we can
bound the search for next page, to get a linear behavior (though
still not good enough as it will read the entire file backwards if
there's no valid page till then).

f865729e95 videodecoder: Fix initial timestamp in ogg, and a warning.
Don't replace the initial frame's timestamp with a bogus
one calculated from the (incorrect for Ogg) frame number just
because the 'sync time' hasn't changed.

Also, don't output a bogus warning about the output_frame being
NULL when it's being dropped/skipped due to QoS.

e729ad1c9c playback: Always prefer parsers over decoders
...and in playbin2 additionally prefer sinks over parsers.

This makes sure that we a) always directly plug a sink if it supports
the (compressed) format and b) always plug parsers in front of decoders.

88d3b7aeee playbin2: Send flush events when changing subtitle tracks and use new input-selector modes for subtitle tracks
For audio/video we should flush too for fastest stream switches but this
currently isn't possible because the flushes would need to go to the sink,
which then causes state changes and causes all timing information to be
changed.

Should work out of the box in 0.11 with the flush-stop that doesn't reset
the times.
