Description: Video decode in hardware on ARM platform.

This patch modifies the GpuVideoDecodeAccelerator machinery to enable HW decode on certain platforms.

In case of some ARM platforms, the texture memory allocated by GPU(glTexImage2D)
cannot be shared with other devices such as a seperate HW decoder.
So a Pixmap buffer is allocated and an EGL Image is created from the pixmap handle.
This EGL Image is sharable between the HW Decoder and the GPU.
