b3df031908 gl/memory: generate textures with a sized internal format 
Required in order to generate RG and RED textured with GLES3.

132a233f7b gl/memory: implement GL_EXT_texture_rg support 
Which is used by default over the Luminance formats due to it
being color renderable with fbos (and deprecation/removal with
GL 3.x).

9cfd5e5d04 gl/filter: fixup passthrough bufferpool 
In a pipeline like so:
  videotestsrc ! gleffects ! videoconvert ! sink
gleffects was simply passing the videoconvert bufferpool to videotestsrc
and not creating a glbufferpool. videobufferpool would then fail
to allocate from the glallocator.

313dfbb500 gl/upload: switch the 'master' texture for YUY2, UYVY 
From d4bcef3204 on, using a RGBA
texture to hold the data causes the glmemory to have half width
and a scaling of [2, 1].  Using a LA texture solves this problem
however cannot be attached to the framebuffer for copying into
a RGBA texture.  Which will be solved by moving to EXT_texture_rg.

157607989a glmemory: Fix handling of stride with alignement larger then 8 
Setting a scaled factor for X coordinate is not enough as the indexer
will still think stride is shorter and will not fully skip it. Instead,
update width, so the lines are as expected. Combined with the scale, it
will hide the cropped portion.

d7c5444447 gl: do not allocate the target texture of an EGLImage 
The target texture of an EGLImage is the texture bind just
before calling glEGLImageTargetTexture2D.

As we currently only support a gl texture as the source of an EGLImage
the gl texture is actually already allocated when creating the eglimage.

glTexImage2D is called on the target.

8c56e1bba7 gl: Try harder to load symbols from the correct place 
This commit makes the loading of the GModules threadsafe, and
always first tries to load the symbol for the GL library that
is selected for the current context. Only then it falls back
to looking into the current module (NULL), and only as a last
resort the context specific function (e.g. eglGetProcAddress())
is called.

Also add configure parameters to select the names of the library
modules instead of using the defaults, and let the defaults be
independent of the G_MODULE_SUFFIX.

When using with gst-launch, it was not possible to click on the close
cross of the window anymore which is a bit anoying and also because
it's was possible before.

Prior to this commit the GstGLContextCocoaClass was initialized
in the main thread because gst_gl_context_new was called in the
state change function from going from ready to paused.

From this commit this call is done from the streaming thread.
So that the call to [NSApplication sharedApplication];
was not done in the main thread anymore.

We now ensure that by assuming there is a GMainLoop running.
It's for debugging purpose so that's ok to do that. Also
note we already do this assumtion to run app itereations.

The regression had no consequence on the cocoa/videooverlay example
(that should be moved from gst-plugins-gl to -bad) because the
application is responsible for that necessary call.

* 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

303b77eeff [890/906] x11: add display subclass 
GstGLDisplayX11 holds the display connection and name.  Each thread requires
it's own X11 Display connection (initialised from name) due to the fact that
we do not want to call XInitThreads().  Doing so would result in segfaults
when integrating with GUI toolkits Gtk, Qt, etc.

The Display connection is for OpenGL platforms where a constant display is
required in order to share contexts (egl).  In the case of a wrapped context
(added later), we do not have GstGLWindow to retreive the display from so a
'master' connection is used instead.

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.
