MPSAFE TTY - Refactor the keyboard switch code to make all drivers MPSAFE

* Add a per-kbd lock.

* Replace the keyboard kbd_*() macros with function wrappers which acquire
  and release the per-kbd lock on behalf of each keyboard driver.  The
  wrapper code also understands polled mode and will not acquire/release
  locks in polled mode (aka debugger).

* Remove all tokens and locks from the keyboard drivers.

* Do some documenting of non-blocking paths.
