8ed06789ed New debug printing facilities. 
- Can now register a userspace file descriptor as the output for kernel
  print statements through kprintf()
- Can set logging levels for debug print messages, which are separate
  from kernel log events and meant to be more readily visible. Log
  events are recorded in a buffer to be viewed later, though nothing
  actually using logging at the moment.
- Serial output is disabled by default now. You can enable it yourself
  by appending the logtoserial argument to the kernel on boot.
