6141d3fc7e glcolorconvert: add support for converting texture targets
Solved with a simple shader templating mechanism and string replacements
of the necessary sampler types/texture accesses and texture coordinate
mangling for rectangular and external-oes textures.

681cb5b16d glmemory: add support for rectangle textures
Add the various tokens/strings for the differnet texture types (2D, rect, oes)

Changes the GLmemory api to include the GstGLTextureTarget in all relevant
functions.

Update the relevant caps/templates for 2D only textures.

aa32408926 glcolorconvert: order the caps template so that RGBA is first
glcolorconvert ! glcolorconvert would sometimes negotiated RGB
(the first list entry) otherwise.

6bb560a4eb glslstage: initialize output params to 0 before calling gl functions

in debug mode that check that output params are initialized to 0.

ad49a39e5b glcolorconvert: allow outputting multiple textures for gles3 contexts
the USING_GLES2 includes all GLES3 contexts as well which does support
drawing to multiple buffers.  Instead make or decision solely based on
whether glDrawBuffers is available or not.

cfb0d7e9f3 glviewconvert: expose the element on gles2 platforms
We can do everything with gles3 however gles2 restricts us not allowing
separated or frame-by-frame multiview modes due to multiple draw buffers.

f688a8f0b2 glshader: port to using GstGLSLStage objects for string management

0580536fa1 glutils: use gst_element_set_context for setting display/other_context
1. So we get tracking inside GstElement properly when e.g. adding to a bin
2. Removes redundant code.  Now only one place where
   GstContext->GstGLDisplay/GstGLContext transformation occurs
3. Fixes a memory leak in the process
4. Make the retrieval of debug categories thread safe

63bbe9406a glwindow: add API to request a resize event on the next draw
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.

5adde7f98b gl/api: use public rather than private define
HAVE_IOS is only defined for the build of this module so
attempting to use gstgl in iOS would result in incorrect GL
includes.

header.

d45e0f807f glbasefilter: only call gl_{stop,start} if the context changed
Removes the redundant GL object creation/deletion on every
decide_allocation call which is being called for every caps change.
