st/egl_g3d: New EGL state tracker that uses Gallium.

This new (intermediate) EGL state tracker is the base work for EGL
drivers that uses Gallium.  It makes it easier to support new window
systems.

Currently, there is support only for X11.  This driver supports multiple
APIs (OpenVG, OpenGL, ...) and supports hardware acceleration through
winsys/drm.
