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

73af514e1a build: Check for GLES3/gl3ext.h existence
Some OpenGL drivers do not ship this but use GLES2/gl2ext.h instead.
This is also in line with Khronos's recommendations

d57808385c gstgl: Re-enable WINAPI on _MSC_VER
The calling convention may be deprecated, but we still need it for
OpenGL. The build issue was caused by an incorrect syntax being used for
the WINAPI (__stdcall) prototype in function pointers which was accepted
by GCC but is rejected by MSVC.

WINAPI should not be used with MSVC. It also causes a build error.

c459894f78 gl: fix gles3 header usage for older platforms
Some platforms provide an old version of GLES2/gl2.h and GLES2/gl2ext.h that
will fail when including GLES3/gl3.h due to missing typedef's.

Seen on the RPi.

8f4ba29f97 gl: Allow using non-system mesa with both GL and GLES
GCC automatically disable redundance warnings for system headers. As
soon as we start using a non-system installed mesa, we would start
having issues. The test for both wasn't setting any flags, so it would
work but then fail at runtime.

This is being fixed by disabling in the code (where needed only) that
GCC warning. The test is also fixed to avoid the false positive we had.

5adde7f98b gl/api: use public rather than private define
HAVE_IOS is only defined for the build of this module so
attempting to use gstgl in iOS would result in incorrect GL
includes.
Use GST_GL_HAVE_PLATFORM_EAGL instead for choosing the iOS GL
header.

c2471aec81 gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream

9af1cee2f7 [722/906] gl: Fix build on Win32
1) Need to include GL/glext.h on W32 to provide necessary macros
2) W32 macros that pre-processor has by default are different for different
   toolchains. Borland uses __WIN32__, everyone else has _WIN32, so check both.

Side-note: glext.h is not supplied by mingw-w64 at the moment, but can be
downloaded from http://www.opengl.org/registry/
