195981767c gl: add support for A420 conversion
A420 is a four planar format similar to I420 but with an extra buffer
for alpha values.

A common use of the gl stack is for GPU format conversions using
shaders, in which case one can use glupload, glcolorconvert and
gldownload elements to upload their buffer to the GPU context, perform
the conversion on the GPU itself and then retrieve the data to CPU
context.

A420 was not supported. This patch adds said support mainly by adding
the corresponding shader to perform the conversion and updating the
supported caps.

Both A420->RGBA and RGBA->A420 conversions are supported.

abb026ec6a gl,video: Make ptrs to VideoInfo and (GL)AllocationParams immutable
These parameters are incorrectly regarded as mutable in G-IR making them
"incompatible" with languages that are explicit about mutability like
Rust. In order to clean up the code and expected API there, update the
signatures here, right at the source (instead of overriding them in
Gir.toml and hoping for the best).

0ea3279df1 gst-libs: gl: Fix documentation typo and clarify gl_memory_texsubimage
`gst_gl_memory_read_pixels` reads pixels from `GLMemory` into the
pointer, effectively writing to it. This is opposite from
`gst_gl_memory_texsubimage` which reads texture data from `read_pointer`
into `GLMemory`.

Both cases are clarified by changing `read_pointer` to `write_pointer`,
and explaining what `gst_gl_memory_texsubimage` does in addition to
referring back to `gst_gl_memory_read_pixels`.

77db5a0e21 gl: add support for Y412_LE / Y412_BE format
Reuse Y410 code for Y412_LE / Y412_BE except gl format. The gl format is
RGBA16 for Y412_LE / Y412_BE.

Y210 is a 10-bit YUY2, so we may re-use the YUY2 shaders but gl format

0b362e5a4b glcolorconvert: add support for the NV16 and NV61 formats
NV16/NV61 is basically the same as NV12/NV21 with a higher chroma resolution.
Since only the size of the UV plane/texture is different, the same shaders are used as for NV12/NV21.

c5b5ef16d3 gl: GST_EXPORT -> GST_GL_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.

4952fdd956 gl: do not include GL headers in public gstgl headers
Except for gst/gl/gstglfuncs.h

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

76a38dd66a glmemory: base classify and add the pbo memory on top
The base class is useful for having multiple backing memory types other
than the default.  e.g. IOSurface, EGLImage, dmabuf?

The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.

This also moves the format utility functions into their own file.

18f9dfdfe5 glbufferpool: add bufferpool options for the various texture targets
This was chosen over relying solely on the caps as glupload needs to propose an
allocation and set the texture target based on the output caps.  Setting the
caps in the config is currently pointless as they are overwritten in a lot of
element's decide_allocation functions.

This provides a mechanism for the buffer pool to be configured for a certain
texture target when none has been configured.
