rework a bit how we manage EGL extensions

- don't advertise extensions that are not supported
  by any implementation

- remove EGL_ANDROID_swap_rectangle which is not
  implemented by anybody and confuses people

- add some comments about mandatory extensions

-libAgl2 provides software GL ES 2.0 implementation using Pixelflinger2 in external/mesa3d
-
-To build, enable Android.mk, which builds libGLES_android.so, then replace the one built from libAgl in system/lib/egl.
-ES 1.0 functions are not implemented and will cause exit, so do not setprop debug.egl.hw 0 until launcher is loaded.
-
-All functions have little to none error checking.
-Not thread safe, Pixelflinger2 uses some static data.
-
-Most shader functions are implemented, however, most Get* functions for shaders/programs/uniforms/attribs are not.
-No name system for shaders/programs, just using the pointers as names.
-
-Basic glTexImage2D, glTexSubImage2D, glCopyImage2D and glCopySubImage2D are implemented, with a range of 8/16/24/32bpp formats.
-Cube map support is minimal. No mipmapping.
-TexParameter is mostly implemented, supports texcoord wrap modes, and only linear for both min and mag, or nearest for both min and mag filtering.
-Texture names are implemented, but bad.
-
-Frame buffer and render buffers are not implemented.
-
-Depth and stencil are implemented, but not tested.
-Blending seems to work.
-Colorbuffer supports RGBA_8888 and RGB_565.
-
-Vertex buffer objects are implemented.
-Some GL_TRIANGLES and GL_TRIANGLE_STRIPS modes for glDrawArrays and glDrawElements are implemented, but vertex order is probably wrong so culling is disabled.
-
-Basic apps should work, and some libhwui should work, except for frame buffer operations, which will cause exit.
