FreeBSD/alpha. The most significant item is to change the command
argument to ioctl functions from int to u_long. This change brings us
inline with various other BSD versions. Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.
The prototype FreeBSD/alpha machdep will follow in a couple of days
time.
This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)
LFS is temporarily disabled, and will be re-enabled tomorrow.
Includers of this file apparently didn't know that <sys/queue.h>
was a prerequisite and include a semi-random collection headers
until one happened to include it.
Remove unused headers.
Remove all but one instance of the device base name.
Prototype some local static functions.
Consistently reference the softc structure as "sc" rather than "lpt".

- interrupt-driven printing now works (nlpt)
- Rearrangement of bus-related functions into ppb_base/ppbconf
- Addition of ieee1284 interface functions, preliminary parallel-port
PnP support

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h>
instead. This was already done in 4.4Lite for the most important
ioctl headers. Header spam currently increases kernel build
times by 10-20%. There are more than 30000 #includes (not counting
duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
almost self-sufficient (some ioctl headers still need structs from
elsewhere).
- uniformized idempotency ifdefs. Copied the style in the 4.4Lite
ioctl headers.
- ansi prototypes in lpt.c
- a bit of tidying in lpt.c
- ioctl in lpt.c for switching between polling and using interrupts
- added lpt.h - needed for ioctl to allow switching between polling
and interrupt-driven modes.
