Refactor BufferStorage11.

In preparation for transform feedback, BufferStorage11 needs to be able to
handle a non-staging buffer being updated.  Each D3D11 buffer now has an
incrementing data revision associated with it so the most up-to-date
buffer is always known.

Staging buffers are now represented like any other DirectBuffer.
