Bump configvers for different handling of maxusers.

Enable hardwiring of things like tunables from embedded enironments
that do not start from loader(8).

Implement option strings that we can use in #ifdefs (where unavoidable)
as a replacement for the evil #define NFOO. If 'device npx' is in the
static kernel, a synthetic option '#define DEV_NPX 1' will be available
to stick in an opt_xxx.h file. "#if NNPX > 0" can be replaced with
"#ifdef DEV_NPX" and we can get rid of the overloaded meaning of the
device count mechanism.

Make the xxxFILES= list generation generic. This makes it easier to add
things like MFILES= or CONFFILES= without having to modify config code.

Make it possible to specify profiling in the kernel config file.

Do so for LINT.

If a ${KERNEL}.hints file exists, and no hints are specified explicitly,
then include the hints with a marker indicating that it is a fallback.
The kernel side of this is to come shortly.

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!

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.

work unmodified still, new config files won't work on the old ones.

Bump configvers; when the updates to generic/lint get committed, the old
config has severe indigestion.

Made booting with -a work for all configurations. Previously it
only worked for configurations with "swap on generic".

usr.sbin/config/config.y:
- ignore all "swap [on] device ...' specifications except for
warning about them. They haven't done anything related to swap
for almost 4 years, and were previously silently ignored,
except for "swap on generic" which stopped swap${KERNEL}.c
from being generated. Code to support swapping is now deader
than before.

usr.sbin/config/mkswapconf.c:
- don't generate a dummy setconf() function in swap${KERNEL}.c.

sys/i386/conf/files.i386:
- swapgeneric.c is now standard. It should be merged into autoconf.c
so that it doesn't conflict with swap${KERNEL}.c for kernels named
"generic".

sys/i386/i386/autoconf.c:
- don't call setroot() for mfs roots. Since setroot() doesn't do anything
harmful, this was just a waste of time, except possibly for booting with
-a it may have helped prevent an undesireable call to setconf() by
finding a bogus rootdev.
- honor -a for ffs roots. -a now overrides all other ways of specifying
the root device. Previously, -r had precedence over -a, and the -a
handling was usually a no-op.
- don't honor -a for non-ffs roots, since it would currently just get in
the way of a clean panic.

sys/i386/i386/swapgeneric.c:
- don't declare things that are now always declared in swap${KERNEL}.c.
Don't decide things that are now decided in autoconf.c. Code to
support the "generic" case is now dead instead of useless.

3. Config warns you if you don't use -s:

Building kernel with full debugging symbols. Do
"config -s BSD" for historic partial symbolic support.
To install the debugging kernel, do make install.debug

(BSD was the name of the config file I used; I print out the same
name).

4. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
work if a kernel name other than 'kernel' is specified. This is
not absolutely necessary, but useful, and it was relatively easy.
I now have a kernel called /crapshit :-)

5. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
to remove both the debug and normal kernel.

6. Modify all to install the stripped kernel by default and the debug
kernel if you enter "make install.debug".

7. Update version number of Makefiles and config.

Bumped CONFIGVERS. This is not necessary for -current yet, but using
the new config with old system sources gives null pointers for all
vectors.

config, you may need to resynchronize your config file with syntax
or name changes documented in GENERIC or LINT.
