emulatgor opengl: First commit of the host renderer library.

Browse Source 
This is a library which includes all the OpenGL renderer functionality,
it is packaged in a library so that both the renderer process and the emulator
program will be able to use that functionality.

NOTES:
   1) gl_proc.h and GLDispatch.{h,cpp} in this commit will be replaced
      with the decoder auto-generated dispatch in a later commit, the
      auto-generated dispatch is currently missing some extension functions
      required for the renderer.
   2) look at host/include/libOpenglRender/render_api.h for the external
      interface defined for this library (to be used by the emulator).

The following is a description of each component:

FrameBuffer - The main object which manages the framebuffer and color buffers.
              This is a singleton which get initialized through its initialize
              static function. It initializes the OpenGL renderer and must be
              called first. This initialization function is not thread safe so
              it must be called before any thread that is calling to this
              library is created.

FBConfig - Includes a static set of configs supported by the renderer which get
           initialized during FrameBuffer initialization phase. Also,
           an instance of this class includes the a description of one frame
           buffer configuration supported by the renderer.

RenderContext - encapsulate a rendering context state.

ColorBuffer - implements a color buffer object as a texture which can be bind
              as render target or source.

WindowSurface - implements the functionality of a native window which can be
                bound to a rendering context and its target ColorBuffer can
                be specified and replaced.

ThreadInfo - holds per-thread information.

EGLDispatch - loads the EGL plugin library, all egl calls are made through
              this dispatch table which get initialized during initialization
              phase.

GLDispatch - loads the GLES plugin library, all GLES calls are made through
             this dispatch table which get initialized during initialization
             phase - This will be replaced by the auto-generated code of the
             decoder ...

RenderThread - implements a thread that reads command tokens from an IOStream
               and decode it.

RenderControl - implements the host side implementation of the renderControl
                API, when a renderControl token is decoded from the stream
                it is dispatched to this implementation.

RenderServer - implements a TCP server which listens to port number and
               launcges a RenderThread for each new connection.
