This change allows to use this header with the NDK's standalone toolchain.
For the record, the NDK toolchain defines __ANDROID__ as a compiler built-in
macro, this is however not the case currently for the prebuilt binaries that
are being used by the full Android build system, which otherwise defines ANDROID.
This change allows the header to be used by all toolchains properly. Note however
that we should properly should change our toolchain and sources to provide and
rely on __ANDROID__ instead of ANDROID though.

Not yet hooked up to anything in the NDK, but requires renaming
the existing android_native_window_t type everywhere.

ANDROID_swap_rectangle allows to specify the rectangle affected by eglSwapBuffers(), anything outside of this rectangle is unchanged. in particular EGL_BUFFER_DESTROYED only applies to that rectangle. This extension as well as EGL_BUFFER_PRESERVED allow major optimizations on surfaceflinger, which can redraw only the dirty area during compositing.
However, ANDROID_swap_rectangle allows further optimizations in EGL by reducing the amount of copy-back needed. ANDROID_swap_rectangle is particularily important for software implementations.
- Currently the lock/unlock path is naive and is done for each drawing operation (glDrawElements and glDrawArrays). this should be improved eventually.
- factor all the lock/unlock code in SurfaceBuffer.
- fixed "showupdate" so it works even when we don't have preserving eglSwapBuffers().
- improved the situation with the dirty-region and fixed a problem that caused GL apps to not update.
- make use of LightRefBase() where needed, instead of duplicating its implementation
- add LightRefBase::getStrongCount()
- renamed EGLNativeWindowSurface.cpp to FramebufferNativeWindow.cpp
- disabled copybits test, since it clashes with the new gralloc api
- Camera/Video will be fixed later when we rework the overlay apis
