VP9 encoder allocates too many buffers that are potentially too large.

[GoogleCodeExporter]

The encoder allocates reference buffers before it knows the chroma format of 
the input frames, allocating full-size chroma planes in all cases. This 
increases the memory profile of the encoder unnecessarily. 

Other buffers, such as the post-proc buffer, have the same problem.

Furthermore, the full set of FRAME_BUFFERS (12) are allocated independent of 
the coding mode. 1-pass real-time encoding potentially only requires 3 
reference buffers which would reduce the memory profile of the encoder 
considerably.

First step completed, frames are now allocated at the correct size depending on 
their color format:

This will reduce the reference & various other buffer memory profile by 50% for 
4:2:0 format.
