SW egl returned always EGL_FALSE even when the display was valid.
This made calls to eglSwapInterval to fail on HW since the wrapper
fails if either SW or HW egl fails.
Letting SW eglSwapInterval to return true when display is valid is
ok since spec says that interval parameter is silently clamped.

h/w acceleration is not supported through software gl + copybit anylonger,
instead, h/w opengl must be used. in the system compositor, a new h/w
composition api will be introduced to allow h/w accelerated composition with
overlays and/or 2D blocks.

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

the EGL specification states that this should be treated as though it was
an empty list terminated with EGL_NONE.

fix [2236865] STOPSHIP: bump soft gl and egl minor version number
we lost the concept of vertical stride when moving video playback to EGLImage.
Here we bring it back in a somewhat hacky-way that will work only for the
softgl/mdp backend.
This change makes SurfaceHolder.setType(GPU) obsolete (it's now ignored).
Added an API to android_native_window_t to allow extending the functionality without ever breaking binary compatibility. This is used to implement the new set_usage() API. This API needs to be called by software renderers because the default is to use usage flags suitable for h/w.
there was several issues:
- when a surface was made non-current, the last frame wasn't shown and the buffer could stay locked
- when a surface was made current the 2nd time, it would not dequeue a new buffer
now, queue/dequeue are done when the surface is made current.
for this to work, a new query() hook had to be added on android_native_window_t, it allows to retrieve some attributes of a window (currently only width and height).

fix for [1969185] valgrind errors in new gl stuff
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
