    Keyboard struct lifetime is easy, but the locking is not and is completely
    ignored by the existing code. Tackle this one head on
    - Make the kbd_table private so we can run down all direct users
    - Hoick the relevant ioctl handlers into the keyboard layer
    - Lock them with the keyboard lock so they don't change mid keypress
    - Add helpers for things like console stop/start so we isolate the poking
      around properly
    - Tweak the braille console so it still builds
    There are a couple of FIXME locking cases left for ioctls that are so hideous
    they should be addressed in a later patch. After this patch the kbd_table is
    private and all the keyboard jiggery pokery is in one place.
    This update fixes speakup and also a memory leak in the original.
