fix [2931718] glDrawArrays skips a triangle when more than 70 vertices are used.
a typo prevented the last 2 vertices of a batch to be copied to the front of
the next batch. Instead, the 2 very first vertices were used.

remove copybit hack from software opengl (libagl)
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.

fix [2235414] libagl glDeleteBuffers() crashes
don't dereference null pointers, would happen if one of the array wasn't bound.

s/w OpenGL no detects and handles all any combinations of triangle fans corresponding to a rectangle
this allows fallback to faster copybit code in almost all cases.

fix [1610840] Positional light doesn't work correctly on emulator
This bug was introduced when lighting computations was changed from eye-space to object-space.
The light position need to be transformed back to object-space each time the modelview matrix changes which requires us to compute the inverse of the modelview matrix. This computation was done with the assumption that normals where transformed (which was the case when the computation was made in eye-space), however, normals only require the inverse of the upper 3x3 matrix while transforming positions requires the inverse of the whole matrix.
This caused the interesting behavior that lights were more-or-less transformed properly, but not translated at all, which caused improper lighting with directional lights in particular.
There was also another smaller bug affecting directional lights: when vertices are read, only the active component are read, the other ones are ignored, later, the transformation operations are set up to ignore the unset values, howver, in the case of lighting, we use the vertex in object space (that is, before it is transformed), and therefore were using uninitalized values; in particular w.

update surfaceflinger, libui and libagl to the new gralloc api
- 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
