Move most of the logic in glslang.y to ParseContext. This will make it
easier to change the code in the future.

Only a few specific bits of logic are kept in glslang.y:

* Disabling a parsing rule when a given shading language version is
  being parsed. This makes it easier to check the grammar against the
  grammar in the GLSL ES specs.
* Scoping calls that need to be paired with another call. It's much
  easier to check these for correctness when the paired calls are next

This gives the D3D back-end access to the GL state almost anywhere.
This uses the onDestroy hook for Textures to push errors up from
destructors, although they still don't quite make it to the Context.

There are places, such as in EGL object (Context/Surface) destruction,
where we end up calling through to GL implementation internals without
having access to a gl::Context. We handle this via a proxy Context
to a Display, basically a null context, that has access to impl-side
state like the Renderer pointer if necessary. It does not have access
to the normal GL state.

Also Pass gl::Context to RefCountObject::release(). Since we're using
destroy() methods now, we should not ever call the destructor directly.
