jonathan 6d836436ac Commit snapshot of pmax console rework as basepoint for 1.3.2 pullup: 
* Do rcons output properly, using cn_tab->cn_dev which points
   at rcons cdevsw entrypoints.

 * The pmadx console code was using keyboard (serial) device
   (major,minor) for raster consoles with special code in the keyboard
   drivers to catch output intended for consoles, pull it off the device
   queue, and print them via cnputc().
   Ifdef out  RCONS_BRAINDAMAGE.

* Other minor cleanup to pmax scc driver.
