22025511b4 Clean up most of the "XXX"-tagged items:
- The code that creates hints.c and env.c from the skeleton files
  moved into separate functions.

- Sanity checks for missing "ident" and "cputype" directives moved
  into main(), alongside the existing check for "machine".

61ede7eeac Clean some code that became obfuscated over the years:
Don't keep duplicate files in the files list just to
mark the device as "known" later.  XXX: Since the
device list isn't unique (there can be two "device foo"
directives, as this the case with LINT+DEFAULTS), we
have to traverse it all to mark all copies of the same
device as "used", but this is not worse than it was.

f37a929ca1 Kill count device support from config. I've changed the last few
remaining consumers to have the count passed as an option.  This is
i4b, pc98/wdc, and coda.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device.  This broke things like the snd_emu10k1 device, which required
quotes to make it parse right.  The no-longer-needed quotes have been
removed from NOTES, GENERIC etc.  eg, I've removed the quotes from:
   device  snd_maestro
   device  "snd_maestro3"
   device  snd_mss

I believe everything will still compile and work after this.

a97024f7c6 Not particularly pretty hack to generate rules to make .ln files
from .c files. Actually, this is overkill, as the .ln file targets
are assumed from .? (any) files. This is not a problem in practice,
merely a bit untidy, as the linting rules DTRT. See the sys/conf/*
and sys/mk/* files for usage.

7a2eb19dbf Commit some infrastructure for turning on -Werror for kernel compiles.
It doesn't actually do it yet though.  This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on.  make -DNO_WERROR would also bypass all of it.

faa913d76d Fix buffer overflows in filenames. If you had a path > 80 characters
for your /usr/obj/path/to/my/files path to the kernel, then weird
things happened.  make buildkernel would fail because config was
dumping core or generating bad file names (depending on the lenght of
the path).

While I was here, also use strlcpy, strlcat and snprintf (or asprintf)
as necessary.  Minor format policing for the snprintf calls as well.

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!

3f664fc689 A checkpoint of a part of a work-in-progress. Some more cleanups for
config(8).  This commit allows control of the creation of the
#include "foo.h" files.  We now only create them explicitly when needed.
BTW; these are mostly bad because they usually imply static limits on
numbers of units for devices.  eg: struct mysoftc sc[NFOO];
These static limits have Got To Go.

b5cda9cb3c Support getting *.$MACHINE from sys/conf as well as sys/$MACHINE/conf.
This would mean that we could move files.alpha, files.i386, files.pc98
etc all next to conf/files, and the various Makefiles next to each
other.  This should go a long way towards committers "seeing" the
Alpha etc stuff and remembering to update that too as it would be
right next to the i386 config files.  Note this does not include
the GENERIC etc files as they can't be shared.  I haven't actually
moved the files, but the support is here for it.  It still supports
the per-machine conf directories so that folks working on a new arch
can just distribute a subdir of files.

1e306bb1c6 When specifying additiona user-specified kernel compilation source
files in a 'files.XXX' file, config allows non-FreeBSD source files
with the same name as a FreeBSD source file to override the latter,
and in this situation it issues a warning.

However, if one of the user-specified files is actually a FreeBSD
source file (perhaps your kernel has some custom option that requires
that file), config mistakenly thinks it's a completely new file
and goes ahead and overrides all previous information for that file
(and issues the warning).

Fix this.

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.
