d7f508acbb glviewconvert: Fix stereoscopic handling w/ texture-target 
The addition of texture-target negotiation broke stereoscopic
handling when not in passthrough mode, so fix that.

28dbe4fffc glmemory: add gst_gl_memory_allocator_get_default 
Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.

Fixes GL upload on iOS9 among other things.

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.

b8c1ecf268 glviewconvert: remove set_format 
We need the caps to be able to
1. check the caps features
2. get the requested texture-target on input/output

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.

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.

9b1eb32c49 gl: initialize output params to 0 before calling gl functions 
The client side API of the Chromium's GPU Process has asserts
in debug mode that check that output params are initialized to 0.

7b583526e9 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.
