in the mixed interlace-mode.

ed8504e590 video-overlay-composition: fix GSlice alloc/free size mismatch
Fix copy'n'paste bug which made us allocate a slice of the
size of a rectangle for the overlay composition, but then
free it passing the size of an overlay composition, which
is not something GSlice takes to kindly, resulting in scary
aborts like:

***MEMORY-ERROR***: GSlice: assertion failed: sinfo->n_allocated > 0

Also, g_slice_new already includes a cast, so remove our
own casts, without which the compiler would probably have
told us about this ages ago.

8feaebb6eb videodecoder: Expose _negotiate function
This is to be called by decoders once they have set the output format
in order for (re)negotiation to be triggered as early as possible.

eacb9ee554 video: add method to get offset and scale for a format
Add a method to get the offset and scale values to transform the color values of
a format to their normalized [0.0 .. 1.0] range. This is usually required as
the first step of a colorspace conversion.

a18c098f82 video: add option to unpack and truncate the range
Add an unpack option to specify what to do with the least significant bits of
the destination when the source format has less bits than the destination. By
default we will now copy the most significant bits of the source into the least
significant bits of the destination so that the full color range is represented.
Add an option to leave the extra destination bits 0, which may be faster and
could be compensated for in the element algorithm.

c68683c15f videodecoder: avoid crash when getting duration
Check that we have a valid output_state before attempting to use it to calculate
the duration of a buffer. It is possible that we don't have a state yet, for
example when we are dropping the first buffers.

9a79a145b1 videodecoder: Remove gst_video_decoder_get_timestamp function
Interpolating the timestamps from the picture numbers
does more harm than good, getting it wrong in a lot of
cases (especially reverse playback). Removing it in favour
of simply incrementing the timestamps until there's
something better

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.

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.
