Rename CPUState to CPUOldState.

Upstream qemu has split the cpu state into two new data structures:

  CPUState -> is used to model the CPU state through the QEMU
              object model.

  CPUArchState -> actually a macro that aliases CPUArmState,
                  CPUX86State or CPUMIPSState.

Both were part of the "CPUState" in the current emulator sources.

Previous patches introduced CPUArchState, as a simple alias to the
machine-specific state. This patch renames any use of CPUState in
the current code to CPUOldState, except within target-*/ directories
where it is replaced by CPU${ARCH}State instead.

This will allow bringing the upstream CPUState definition in the
source tree, and slowly migrate everything to the right location.
