36ce08826e video-info: add gst_video_info_align_full()
When using gst_video_info_align() user had no easy way to retrieve the
padded size and height of each plane.
This can easily be implemented in fill_planes() as it's already called
in align() with the padded height.

Ideally we'd add a plane_size field to GstVideoInfo but the remaining
padding is too small so that would be an ABI break.

73a628923e video-info: fix GST_VIDEO_INFO_FIELD_HEIGHT() with frame odd height
We want to round up when halfing height.

I do have a test for this but it relies on my new video-align tests so
it's part of the next commit. Recording the fix separately if we want to
backport this fix to the stable branch.

93daa1435a Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means we
no longer need the macro there, but for most types in base/gst-libs we
don't want to break ABI, which means it's better to just keep it like it
is (and use the `#ifdef` instead).

3880eb819a video: Add GST_VIDEO_INFO_FIELD_RATE_N() macro
Add a new macro that gives you the rate of the fields, which is the
numerator of the field-rate for ALTERNATE interlacing video and FPS for
progressive and other interlacing formats.

4879983253 video: Add GST_VIDEO_INFO_FIELD_HEIGHT() macro
Add a new macro that gives you the height of a field. It returns the
height of the full frame unless split-field (alternate) interlacing is
in use. Also GST_VIDEO_INFO_COMP_HEIGHT macro now uses this new macro to
get the height for its calculation.

0fbe4634a6 video: Add gst_video_info_set_interlaced_format()
Add a helper to set the interlacing mode while creating the GstVideoInfo
in addition to format and resolution. Using this helper will ensure that
size is correctly calculated for split-field interlacing mode.

bd9c7b36d8 video: Add GST_VIDEO_INTERLACE_MODE_ALTERNATE
Add a new interlace mode enum to represent buffers containing a single
field of an interlaced video in a buffer. The name is based on the
equivalent video format in the V4L2 API, V4L2_FIELD_ALTERNATE:

https://01.org/linuxgraphics/gfx-docs/drm/media/uapi/v4l/field-order.html

Since caps fields are optional, we also introduce a new caps feature,
"format:Interlaced" that always goes with "alternate" interlace mode to ensure
that caps for this incompatible format are incompatible with other interlaced
and progressive video caps.

ae429de8f6 video: GST_EXPORT -> GST_VIDEO_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

79809633de video-info: Add optional field-order caps field for interlaced-mode=interleaved
Usually this information is static for the whole stream, and various
container formats store this information inside the headers for the
whole stream.

Having it inside the caps for these cases simplifies code and makes it
possible to express these requirements more explicitly with the caps.
