359e361881 gl/egl: support direct dmabuf import with external-oes only formats
Allow creating EGL images from DMA buffers in formats that the driver
only supports for the external-oes texture target.

Pass the intended texture target to gst_egl_image_from_dmabuf_direct so
that _gst_egl_image_check_dmabuf_direct can decide whether to create an
EGL image for a format that can only be targeted at external-oes
textures by the driver. Allow creating GstGLMemoryEGL objects from these
DMA buffers.

5d0e191710 gl/egl: Add gst_egl_image_from_dmabuf_direct() function
The colorspace conversion happens during the upload so the necessary hints
must be provided to ensure that the conversion works correctly.

At least the Mesa Intel driver will create a texture without error but
produces an incorrect result. Use eglQueryDmaBufModifiersEXT() to check if
non-external upload is supported for the given format.

Based on a patch from Carlos Rafael Giani <dv@pseudoterminal.org>.

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.

c98f92ee03 gldownload: Add dmabuf exporting
This patch adds code to gldownload to export the image as a
dmabuf if requested.  The element now exposes memory:DMABuf as
a cap feature, and if it is selected, the element exports the
texture to an EGL image and then a dmabuf. It also implements a
fallback to system memory download in case the exportation failed.

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

5efc2e8705 gl/egl: replace gsteglimagememory with an EGLImage wrapper
That can be passed to GstGLMemoryEGL.

This also ports the dmabuf uploader to GstEGLImage and GstGLMemoryEGL.
