f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

6c54a82eb6 Re-support "tape" as an alias for device and clean up a bit more cruft
left over from the original system (d_dk was for preassigned iostat unit
numbers for disks)

c1454d67ec Add option "-d destdir" which instructs config to use another output
directory than the default one. If the option is not given, then the
output of config is exactly as before. Only when an alternate output
directory has been specified will config modify its behavior.

Additional changed:
o  Remove the now conflicting and unused NODEV define. It
   conflicts with NODEV in sys/param.h.
o  Rename the now conflicting MACHINE token to ARCH. It
   conflicts with MACHINE in sys/param.h.
o  Fix some easy style bugs.
o  Fix some easy grammar bugs in the manpage.

2da5c22ea3 Don't include trailing whitespace in ID tokens before comments. ie:
options FOO=10		# comment
would give FOO the value of "10		" and that caused unwanted
touches on the opt_*.h files.

I hope I've got this right..

ef354ff70d Understand 'config kernelname' and pretend it was a
'makeoptions KERNEL=kernelname'.  Warn about any trailing stuff as it's
not handled here.  This is a simple bandaid, hopefully to head off some
complaints from certain people.

96217b0fbc More cleanups, tweaks and features.
- make this work:   options FOO123=456   *without quotes*
- grumble (but accept) vector xxxintr, and tty/net/bio/cam flags.
- complain if a device is specified twice (eg: 2 x psm0)
- don't require quotes around:  port IO_COM2
- recognize negative numbers.  (ie: options CAM_DEBUG_UNIT=-1)
- GC some more unused stuff (we don't have composite disks from config(8)).
- various other nits (snprintf paranoia etc)

e6fbbbe459 Further cleanups. i386_ioconf.c and alpha_ioconf.c were essentially the
same and were merged into a single newbus_ioconf.c.  CG'd some more unused
code.

188334f6de Get out the blow torch and hack away all the unused stuff. Note that
I zapped the MACHINE_MIPS stuff, it isn't likely to be useful apart from
recognition of the machine name.  It would be reasonable to expect new
ports would look something like the alpha/i386 from a config perspective.

659d2a2071 Remove support for "port none" and "port auto", it gains nothing,
non-standard and not used. "port auto" is equal to "port?" or missing "port"
keyword now. "port none" is really probe routine task (return -1 for
no ports).

227941d5de Implemented a new keyword `disable'. This should be useful for controlling
dangerous drivers in GENERIC.

Removed non-comments on #endifs in config.y.

6d41b96fd7 Implement support for conf/options and i386/conf/options.i386
Note that this code is dormant unless the options files exist.
Also, parsing of quoted options in the config files is improved.

What this allows, is all the options in LINT to be specified to be
configured as #defines in a file rather than on the CC command line at
kernel build time.  This means that 'make depend' will catch dependencies
on actual *options*, meaning that you can run 'config' and 'make depend'
in complete safety WITHOUT removing the compile directory each time.

Unfortunately, this requires a pass over the source to get the individual
files to #include the new .h files that would be generated by config.
This has a small compile time penalty (appears up to about 2% slower)
from a "fresh" build.  Of course, you should not be needing to do complete
rebuilds very often once this was completed, so it would be an overall
win for most people.

Since this code is dormant and we've got a lot of other things happening
on the kernel tree at the moment (prototypes, devfs, static declarations
etc) I am not planning on doing any changes to activate this feature just
yet.

31acd246c0 Allow the specification of the controller bus when wiring down scsi buses.
This is performed by using a line similar to:

controller scbus0 at ahc0 bus 1

to wire scbus0 to the second bus on an adaptec 2742T controller.

babb4e927f Add a new `conflicts' flag for telling when a device is in conflict with
others.  The flag can be put in descriptive locations, e.g.:

device sb0      at isa? port 0x220 irq 7 conflicts drq 1 vector sbintr
or
device psm0	at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr

But is nonetheless boolean only.  You can't turn conflict checking off for
only a given type of conflict.  I didn't deem it worth the trouble at this
stage, and it's far better than the ALLOW_CONFLICT_* that preceeded it.
