f9617bf3f4 x(v)image: use gst_video_meta_set_alignment()
Use the new API to tell buffer consumers about alignment details.

This change is backward compatible as non ported elements can safely
ignore the alignment information and keep processing buffers as they use
to, copying if necessary.

923d72d399 x/xv_image_sink: rename for consitency
Insert '_' to match the CamelCase. This is needed so that the plugin docs can
guess the names from the type name.

3fd184da78 ximage: do not allocate extra alignment slack for shared memory
A previous patch increased allocations by 15 bytes in order to ensure
16 byte alignment for g_malloc blocks. However, shared memory is
already block aligned, and this extra 15 bytes is not needed. Since
shared memory limits are low compared to RAM, we remove this waste.

e9c6c833c9 videopool: update video alignment after applying
Video buffer pool will update video alignment to respect stride alignment
requirement. But haven't updated it to video alignment in configure.
Which will cause user get wrong video alignment.

8baf1ec500 videopool: update buffer size after video alignment
Update the new buffer size after alignment in the pool configuration
before calling the parent set_config. This ensures that the parent knows
about the buffer size that we will allocate and makes the size check
work in the release_buffer method.

9b3849db1c x11: fix alignment in non-XSHM case
Align the allocated memory to 16 bytes. When doing XSHM we are already aligned
to a page boundary but without, we use plain g_malloc, which could allocate
aligned on 8 bytes only.

04a2610444 video: improve frame_flags
Rename the frame_flags to flags. Because they are flags on the frame object it
does not need the redundant frame_ prefix.
Change the order of the metadata constructor so that the flags come before the
format and dimension arguments.

ddce68a5c2 video: More video helper library improvements
Make a new GstVideoFormatinfo structure that contains the specific information
related to a format such as the number of planes, components, subsampling,
pixel stride etc. The result is that we are now able to introduce the concept of
components again in the API.
Use tables to specify the formats and its properties.
Use macros to get information about the video format description.
Move code to set strides, offsets and size into one function.
Remove methods that are not handled with the structures.
Add methods to retrieve pointers and strides to the components in the video.
