Log:
  kern_cons: add a stub kbdinit for configs with no keyboard/console drivers
  
  A weak symbol here is decidedly cleaner than any #ifdef soup or relocating
  kbdinit, the former leading to maintenance required on addition of any
  console/keyboard drivers and the latter pushing kbd init bits away from
  where they're used.

Modified:
  head/sys/kern/kern_cons.c
