[514/906] add GstGLMemory and allocator implement custom GstMemory for GL textures currently map/unmap returns NULL although it might be favourable to upload/download/cache the image data

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.

#include <gst/gl/gstglbasememory.h>
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 https://bugzilla.gnome.org/show_bug.cgi?id=784779
