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.
