4c8f264686 glbasebuffer: remove unsed memory subclass
The functionality has been split into GstGLBaseMemory and GstGLBuffer.

2b7495bbc1 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.

6cf8da132b 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.

27e724df8f 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

3591c6bfa0 gluploadmeta; remove convenience helper API
It was not really useful as if one knows about libgstgl, one can just use
GLMemory objects directly.

50337e601e 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.

1aa3911d40 gl libs: Add glviewconvert helper object
Add API for a helper object that can convert between different
stereoscopic video representations, and later do filtering
of multiple view streams.

6e88b07cc5 gl: new glbasebuffer GstMemory object
Provides generic handling of GL buffer objects accessible using
the GL bind points (GL_ARRAY_BUFFER, GL_PIXEL_*_BUFFER).

Implementation based off the current GstGLMemory.

f2af65ee2d 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.

92d00d0233 gl: Move GstGLMixer to the plugin for now
It depends on GstAggregator and we don't want to install headers
for that yet.

0ae3c984aa gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* 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
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream

cf5e910d9b [793/906] add a GstGLContext object that will be the basis of OpenGL contexts
At the moment it just sits in between GstGLDisplay and GstGLWindow
performing some of the stuff that GstGLWindow used to do.

dd7e054e2c [732/906] build: fix repeated typedefs
Write forward declarations in another way to avoid
repeated typedefs "error: redefinition of typedef".
Raised when using i686-apple-darwin11-llvm-gcc-4.2
It seems that C apple compiler does not support
C11 feature.
