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.
If sanity checks on the buffer size allocated by XvShmCreateImage() fail,
call on g_set_error(), rather than just logging a warning, as this
failure is fatal.
Add a sanity check on buffer size when the video format is RGB. This adds to
existing checks on various YUV pixel formats.

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.

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.

Make a new refcounted xvcontext object that handles the X connection.
Use the xvcontext to allocate images and windows. Move some code
around so that all X calls are made from the xvcontext object.
Make a GstXvImageAllocator object that allocates images from the xvcontext. We
can implement a copy function now for these memory objects now.
Make the bufferpool use the xvimageallocator object for its images.
We don't want to share the memory between buffers because that could
cause the memory of the bufferpool buffers to be copied and replaced
with other memory.
This is a hopefully a temporary fix until we can figure out how to share
properly.

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.

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.
Add support for the VideoAlignment option in the bufferpool. The extra
configuration options can be used to request special padding and alignment
requirements for the video buffers.
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.
Provide a method to list the supported metadata apis.
Activate the video metadata on buffers when a downstream element configured the
bufferpool to support that api.
Use GstVideoInfo to keep track of the configured format.
Add GstMetaVideo to buffers, disabled by default for now until we can have it
enabled with a property on the bufferpool configuration.
