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.
