Support for eglChooseConfig with configs==NULL.
Also added small change to query EGL_LARGEST_PBUFFER attrib of surfaces.
Fixed error print in QemuPipeStream::readFully.
Those changes make sure that covegl completes & passes on the emulator with Translator
on linux in the backend.

Those are the host side fixups required for the system to load
without failure to the point of bootanimation is run.

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.
