2fd84a6c86 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

6083ad6287 glfilter: Remove hard-coded pad templates
Add a function to install the default RGBA pad templates,
but don't make them required so that there can be
GstGLFilter sub-classes with different input/output
caps if they want. Remove the hard-coded RGBA restriction in
the set_caps_features call, as it will be taken care
of by intersecting with the pad templates.

Update all the sub-classes to match

956c4d0bde gl/format: use our own GL format enum's instead of gstvideo's
They can describe in more detail (such as component sizes) the requested format.

b1fd1d34bd gl/effects: use non-PBO GLMemory for internal textures
middle textures in gleffects do not need to use GstGLMemoryPBO as they
aren't transfering data to/from the GPU. This will cost too much DMA
memory and cause performance issue. Change the allocator to use non-PBO
GstGLMemory.

3f7b549881 gl/utils: move gen_shader() to the plugin and remove del_shader()
gst_gl_context_del_shader() can be replaced by a g_object_unref().
gst_gl_context_gen_shader() should be replaced by using GstGLSLStage.

cafcde5586 glfilter: remove display_init/reset
They are mirrors of GstGLBaseFilter's gl_start() and gl_stop() virtual methods
so use them instead.

8c02a47741 gleffects: fix shader compilation with legacy opengl
All the gleffects shaders can be run against a gles2 or a legacy opengl glsl
compiler but weren't being advertised as such.

b25807c382 glshader: port to using GstGLSLStage objects for string management
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program.  The uniform/attribute

ba5bf50d5f gl: add and use gst_gl_internal_format_rgba
Previously when compiling GstGL with both GL and GLES2,
GL_RGBA8 was picked from GL/gl.h. But a clash may happen at
runtime when one is selecting GLES2.

gst_gl_internal_format_rgba allows to check at runtime
if it should use GL_RGBA or GL_RGBA8.
