Step 1: Changing CommandBufferHelper to only use a portion

of the command buffer. This brought out the fact that
there were lots of places in the code mixing size in bytes
with num command buffer entries.

This fixes most of those issues. No public interface
uses num command buffer entries except 
gpu::CommandBuffer::State where it makes sense.
