  Implement EGL_ANGLE_explicit_context
  
  Implementation of EGL_ANGLE_explicit_context. Includes new libGLESv2 entry
  points and exports, libANGLE entry points, extension declarations for
  eglGetProcAddress, and unit tests. Autogeneration scripts have been
  modified to produce entry points, exports, eglGetProcAddress function
  table, extension function pointers, and function declarations.
