* Always include the public arch_debugger.h headers. The structures defined

there are prefixed with the respective architecture name. Useful for remote
  debugging a different architecture.
* <x86/arch_debugger.h>: Introduced a structure for the FPU state, so that it
  isn't left to the debugger.
* Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for
  bdb compatiblity, but isn't really needed.
* Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since
  it reinits the FPU after saving the state. This resulted in weird results
  when debugging functions using the FPU. We now use fxsave, if available.
  Otherwise fnsave + frstor should be used -- not fully implemented yet.
  Same for arch_set_debug_cpu_state().
