- Add the new critical_t type used to save state inside of critical

  sections.
- Add implementations of the critical_enter() and critical_exit() functions
  and remove restore_intr() and save_intr().
- Remove the somewhat bogus disable_intr() and enable_intr() functions on
  the alpha as the alpha actually uses a priority level and not simple bit
  flag on the CPU.
