[Mesa-dev] [PATCH 01/14] r600g: remove the "atom" variable from r600_command_buffer

r600_command_buffer is not an atom.
The "atoms" have evolved into state slots (or groups of state slots) where
you can bind states. There is a fixed amount of atoms (state slots)
in the context.
The command buffers are nothing like that. They represent states, not state
slots.
We could probably give r600_atom a better name someday.
