New argument &key onewayp to protocol functions

Users can now decide on a call-by-call basis whether to request replies
to commands.  (Command definitions should no longer include #x80 literally.)

For example, anyone working over bluetooth would be well-advised for
speed-reasons to specify :onewayp t whenever calling a function that
doesn't return anything useful anyway.

We still default to requesting replies though.

Example:
  (nxt:nxt-play-tone :onewayp t :frequency #x500 :duration #x100)
