7e8050728a mpeg2dec: Re-implement pool handling 
This is a rewrite of the pool negotiation and configuration. Direct
to output decoding is now achieved by configuring the pool using
video-alignment. This removes copies when dealing with any elements that
supports VideoAlignment, and enable usage of generic video buffer pool,
XVImagePool and GLPool. It drops the crop meta implementation for now.

f3e8dcb9de mpeg2dec: Fix handling of stride 
A pipeline like:

gst-launch-1.0 filesrc location=file.ts ! tsdemux ! mpegvideoparse ! mpeg2dec  ! vaapisink

would look bad when file.ts contains 704x576 video, because vaapisink would
give you buffers of stride 768, but libmpeg2 was not told about this and
used a stride of 704.

Tell libmpeg2 about the stride from  downstream; in the process, teach it to
reject buffer pools that don't meet libmpeg2's chroma stride requirements

6b887060b1 mpeg2dec: do not reset the whole video info when setting size 
New changes to gstvideo will reset all the video info state
when calling _set_format, overwriting what was previously set
in the preceding code.

The comment says the following code is meant to preserve the
pre-crop size, so let's just keep the size and related data
 as this does not seem to break anything else (this is what
the _set_format call would have set before the change that
reset all data, except the colorimetry).

866f60cce6 mpeg2dec: make the aspect ratio calculation more accurate. 
Utilize the libmpeg2 api: mpeg2_guess_aspect() to guess the
aspect-ratio if we don't have a valid upstream PAR.

6d35db313f mpeg2dec: Don't error out when there is no associated buffer 
In 0.10, having mpeg2dec occasionally tell us to output a frame that
was never decoded was just ignored, so do the same in 1.0

do not check if it is NULL or not.

870fe4e7ec mpeg2dec: Correctly flag output buffer interlaced state 
If the sequence is not flagged as progressive its buffers are marked
interlace mode mixed. There is an individual picture flag indicating
whether picture in the sequence are interlaced or not. This is used
along with the new GST_VIDEO_BUFFER_FLAG_INTERLACED to correctly and
completely indicate the buffer's interlaced state.

Also, TFF and RFF should only be set if the sequence is not progressive.

e0a5d6de60 mpeg2dec: Store temporary buffers out of the way 
When mpeg2dec needs to do cropping (because downstream can't handle it),
we need temporary buffers to decode to.

Use the user_data field to store those, and unify the rest of the code
that needs to touch a buffer (regardless of how/where it was allocated).
