man pages up to mdoc guidelines and fix some minor formatting glitches.
Also fixed a number of man pages to not abuse the .Xr macro to
display functions and path names and a lot of other junk.
actually have a printer connected or online:
- MAKEDEV: remove all signs of lpa
add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile add lptcontrol
- sys/i386/isa/lpt.c implement the LP_BYPASS flag: when a unit is
opened with this flag set, the printer is
not primed, and no check is made to see that
the printer is online. This can only be used
to pass ioctls. (giving us /dev/lpctl?)
- lptcontrol.c use /dev/lpctl? (LP_BYPASS)
-f flag removed, -u flag added
- lptcontrol.8 document changes in lptcontrol
rewrite using mandoc macros
