This reverts commit 28e1dadbfa.

Incrementing the offset to make the plane aligned causes the image to be
incompatible with what Xv expects. Rather that forcing a memcpy in the
xvimagesink we would like to do adjust the left padding instead.

664adc6e19 gst-libs: use GST_*_1_0 environment variables everywhere 
The _1_0 suffixed environment variables override the

sets the _1_0 suffixed ones, such as jhbuild, we need
to set those to make sure ours actually always get
used.

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.

Add a method to get the offset and scale values to transform the color values of

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.

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.
