acc098a736 gl: Only unbind buffers/vertex attrib arrays if we can't directly bind the vertex array to 0
Binding the vertex array to 0 will unbind everything else already.

In the previous order older versions of the Intel GL driver caused
errors to be printed for every single call when disabling the vertex
attrib arrays after binding the vertex array to 0.

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

61ee2685c0 gl: GL_ARRAY_BUFFER is not a part of VAO state
As a result we need to bind it on every draw in order to have the
correct state in the GL state machine.

8b9a29a97c gl/tests: don't use the default framebuffer
Create our own instead as the default framebuffer may require special
fiddling (like having a visible window) to correctly display/be renderable.

Fixes the remaining GL library tests on OS X

4bbda2b626 glframebuffer: rewrite for a more consistent API
Facilities are given to create fbo's and attach GL memory (renderbuffers
or textures).  It also keeps track of the renderable size for use with
effective use with glViewport().

1153684a94 glmemory: add the texture type to allocate to parameters
Rather than assuming something.  e.g. zerocopy on iOS with GLES3 requires
the use of Luminance/Luminance Alpha formats and does not work with
Red/RG textures.

eb1a9bb9b0 gldisplay: make readding the same context a no-op
With e38af23044 returning the correct contexts,
gst_gl_display_add_context() was susceptible to causing infinte loops when
adding the same GstGLContext more than once.  Fix and add a test for
gst_gl_display_add_context().

Fixes glvideomixer gst-validate tests.

472970324c glcontext: implement checking whether a context has been shared
Some operations are unnecessary when running with only a single GL
context.
e.g. glFlush when setting a fence object as the flush happens on wait.

API: gst_gl_context_is_shared

f688a8f0b2 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
interface has remained the same.

66407b9877 glcontext: fix get_current_gl_api on x11/nvidia drivers

GL library symbol lookup.

78957c45c2 glcontext: track sharedness with a cookie
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.

efa22442a9 [838/906] gl: Use GL_TEXTURE_2D instead of GL_TEXTURE_RECTANGLE
We create our textures (in Desktop GL) with GL_TEXTURE_RECTANGLE,
vaapi attempts to bind our texture to GL_TEXTURE_2D which throws a
GL_INVALID_OPERATION error and as thus, no video.

Also, by moving exclusively to GL_TEXTURE_2D and the npot extension
we also remove a difference between the Desktop GL and GLES2 code.
