dc02d47092 glbasebuffer: remove unsed memory subclass 
The functionality has been split into GstGLBaseMemory and GstGLBuffer.

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

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

and GstGLMemory's transparent support for downloading textures.

Adding this private header to the list of sources. We don't want to make
this header public, but we need it in the list of sources otherwise it
won't be included in the tarball. This fixes make distcheck.

6bb113f685 gl: add a sync meta for synchronizing across GL contexts 
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.
