Major ppbus updates from the author.

 - ppbus now supports PLIP via the if_plip driver
 - ieee1284 infrastructure added, including parallel-port PnP
 - port microsequencer added, for scripting the sort of port I/O
   that is common with parallel devices without endless calls up and down
   through the driver structure.
 - improved bus ownership behaviour among the ppbus-using drivers.
 - improved I/O chipset feature detection

The vpo driver is now implemented using the microsequencer, leading to
some performance improvements as well as providing an extensive example
of its use.
