Subject: [PATCH] efl: introduce --with-x11, --with-opengl and --enable-wayland

 * --with-x11 takes one of:
   * xlib: use standard Xlib (used if not windows or ps3)
   * xcb: use new xcb library
   * none: do not build x11 (used if windows or ps3)

 * --with-opengl takes one of:
   * full: complete OpenGL support (used if not windows or ps3, ???)
   * es: reduced version (OpenGL-ES)
   * none: do not build OpenGL (used if windows or ps3, ???)

 * --enable-wayland: disabled by default

These are not used as they should yet, will take more work in the
engines to make it happen.
