* Changed arch_debug_save_registers() to take an arch-specific structure

arch_debug_registers instead.
* Call arch_debug_save_registers() on all CPUs when entering the kernel
  debugger.
* Added debug_get_debug_registers() to return a specified CPU's saved
  registers.
* x86:
  - Replaced the previous arch_debug_save_registers() implementation. Disabled
    getting the registers via the gdb interface for the time being.
  - Fixed the "sc", "call", and "calling" commands to also work for threads
    running on another CPU.
