Add parsing of stereoscopic metadata, and place into the caps to
the decoder.
Fix parsing of Advanced Mutual Exclustion objects.

Based on a patch by HyeJin Choi <meeshel78@hotmail.com>
Provide new frame-packing property to directly set
x264enc frame packing, or pass through upstream settings
The explicit layout from the frame-packing property is
preferred over any info from the caps.
a52_init initializes the IMDCT global state as well as creating
a new state. When two A52 decoders are created (eg, when two AC3
tracks are contained in a video), calls to a52_init may happen
at the same time, and the IMDCT initialization is not reentrant.

This allow using external pools that have different strides from the
default. These strides need to respect certain rules, which we check
and if these are not met, we fallback to generic pool.

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.

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

The meaning of the max latency is *not* the maximum latency this element will
introduce. It is the maximum latency this element can endure without
overflowing any buffers, which is infinite for x264enc.
Fixes latency configuration in zero latency mode, where max latency was
becoming 0... which usually won't work well if something else introduces
latency as then max < min in the end, and latency configuration just fails.
There is no reason x264enc should enforce a maximum allocation size.
The maximum is normally set by buffer pool which cannot grow, but we
don't offer a buffer pool. This would lead to stall when used with
element that don't implement allocation query.
