Changed a way to query codec element.
The query routine that copies some data from device is called when each element is used.
However, the codec information is static data and it does not
need to copy data from device everytime. So, the data is cached in the driver and
this module gets them from driver, not device.

As flushing buffer while decoding video, it makes internal buffers of avcodec flush.

Changed a way to use device memory effectively.
Divide device memory into small, medium and large size of buffer
to use the memory effectively when decoding many contexts.
In case of meta data such as width, height, framerate and etc,
each context uses 256byte memory region and utilizes the large size of memory
when copying video and audio buffer.
