396e04cf69 gl/memory: store the internal format as the texture format
Instead of having special cases at each GL texture creation, upload,
readback or copy for all non-8-bits-per-components.
Simply store the more specific format and retrieve the generic
component/type tuple from that.

Introduce a helper function for retrieving the generic GL format (RGBA,
RGB, RG, R, L, A) and type (BYTE, SHORT, SHORT_5_6_5) from a sized
GL format enum (RGBA8, RGB565, RG8, etc).

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

ea6bed111b glformat: fix the usage of GST_GL_RGB565
GL_RGB565 is sized internal glformat, the corresponding glformat
should be GL_RGB and type is GL_UNSIGNED_SHORT_565. Otherwise will
return GL_INVALID_ENUM when creating texture.

8d3d6d3595 gl/format: correct return enums in gst_gl_format_from_video_info
In commit

> 956c4d0 gl/format: use our own GL format enum's instead of gstvideo's

the name and return type of gst_gl_format_from_video_info changed,
but some returns of the old type were missed. Here they are
updated to the correct type.

054b26411a gl/format: use the unsized format for RGB on GLES2
In GLES2 GL_RGB8 doesn't exist so we cannot use it, use GL_RGB
instead.

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.
