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.

5ab3a38973 gl: add a GL buffer based GstMemory 
Heavily based on GstGLBaseBuffer that is a subclass of GstGLBaseMemory.
Provides GPU and CPU accessible GL buffer objects by GL handle or by
sysmem data pointer.

af7015602a gl: add a base memory object 
It handles the following
- GstAllocationParams -> gst_memory_init transformation
- Makes sure that map/unmap/create/destroy happen on the GL thread with
  a GL context current.
- Holds a possible sysmem accessible data pointer with alignment.
- Holds the need upload/download transfer state

caee3e41f9 gl: add convenience function for the start of a video frame

GstVideoAlignment.

cd584d215c gluploadmeta; remove convenience helper API 
It was not really useful as if one knows about libgstgl, one can just use
GLMemory objects directly.

3545d340b6 gldownload: remove helper api from the library 
It was never used by anyone and is not needed anymore with the element
and GstGLMemory's transparent support for downloading textures.

610f965be8 libgstgl: gstglcontext_cocoa: kCGLPFAStereo has been deprecated in 10.11 
Also since the version scheme has changed (to include the micro number) since
10.10, use the MAC_OS_X_VERSION_* macro to avoid confusion.

fa1c4e552c glmemory: take subsampling into account for rectangle textures 
Rectangle textures don't use normalized coordinates so subsampling needs to be
factored in explicitly.

Fixes YUV => RGB conversion for rectangle textures.

on settting sync points.

21df596b8b glupload: Only offer custom allocator with caps features 
To use GLMemory and EGLImage allocators, one need to know the
libgstgl API. This is only expected if the associated caps features
have been negotiated. Generic element that otherwise receive those
allocators may fail, resulting in broken pieline. We don't want to
force all generic element to check if the allocator is a custom
allocator or a normal allocator (which implement the _alloc method).

46b84c6035 glcolorconvert: fix rendering rectangular textures with GL3 
Rectangular textures are unavailable in unextended
GLES2 #version 100 shaders.

Fixes
texture-target=rectangle ! glcolorconvert ! texture-target=2D

There's a couple of differences between GL3 and GLES2/GL

- varying -> in or out depending on the stage (vertex/fragment)
- attribute -> in
- filtered texture access is a single function, texture()
