config(8): Correct the mentioned paper in the SEE ALSO section

FreeBSD's version of the config(8) utility is based on 4.3BSD not
4.4BSD. So correct the mentioned paper in the SEE ALSO section.

mdoc: kill EOL whitespace.

Fix kern/187712: config(8) does not respect KERNCONFDIR.
The impact of this bug is that you cannot build a kernel if both of the
following are true:
1) The kernel config file is in a non-default location
2) The kernel config file uses the "include" statement from config(5).

usr.sbin/config/main.c
usr.sbin/config/config.8
usr.sbin/config/config.h
usr.sbin/config/lang.l
Added a "-I path" option to config(8). By analogy to cc(1), it adds
an extra path in which the "include" statement will search for
files.

Makefile.inc1
Pass "-I ${KERNCONFDIR}" to config(8).

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Enhance config to handle MACHINEs with multiple architectures:

- Passing -m to config will now print the MACHINE and MACHINE_ARCH
given in the passed kernel configuration file and then exit.
- If an option is defined in options.MACHINE with the same name as the
architecture of the kernel being configured, that option will be
considered set. This allows conditional compilation based on CPU
architecture.

Config version is now 600010.

Create the altix project branch. The altix project will add support

This change will let us to have full configuration of a running kernel

The same configuration is also contained within the kernel image. It can be
obtained with:

config -x <kernelfile>

Current functionality lets you to quickly recover kernel configuration, by
simply redirecting output from commands presented above and starting kernel
build procedure. "include" statements are also honored, which means options
and devices from included files are also included.

Please note that comments from configuration files are not preserved by
default. In order to preserve them, you can use -C flag for config(8). This
will bring configuration file and included files literally; however,
redirection to a file no longer works directly.

Use Ns and Sx. -current is 4 not 3.

Apply the axe to some more cruft in config(8). In particular:
- redo the "at" configuration system so that it just syntax checks
to make sure the device you're configuring something "at" appears to
exist. Nuke a bunch of complexity that was responsible for creating
"clones" of wildcard devices and some wierd stuff in a few places
including the scbus config tables etc.
- merge "controller" and "device" - there is no difference as far as
the kernel is concernend, it's just something there to make life
difficult for config file writers. "controller" is now an alias for
"device".
- emit full scsi config into the resource tables. We could trivially
change cam to use that rather than it's own "special" table for wiring
and static configuration. ATA could use this too for static wiring.
- try and emulate some of the quirks of the old system where it made
sense. Some were too strange though and I'd be very suprised if they
were features and not outright bugs. nexus handling is still strange.
One thing in particular is that some of the wierd entries in the
newbus devtables is now gone as it was a quirk side effect of the
wildcard/question-mark cloning above.

GENERIC and LINT still build etc.

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.

like so;

Back out default debug kernel. The flags revert to historical behaviour.

Modify targets for debug kernels: when -g was specified, make will
now build a debug kernel called kernel.debug, and create a stripped
version called kernel at the same time. The two targets install and
install.debug are otherwise unchanged.

Requested-by: dillon

Update man page accordingly.

add -s to synopsis

1. Modify config to issue different code for debugging.
2. Config complains if you use -g:

Debugging is enabled by default, there is no ned to specify the -g option

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.

Make '-n' the default, and introduce a new flag '-r' to get old
behaviour. Also indicate which option(s) are unknown if there are any
old-style options.

Use err(3), add usage(). -Wall clean.

Don't say that swapping is configured by config.

Bring back the `config file in the kernel' feature from the 1.x days. This
is conditionalized by the INCLUDE_CONFIG_FILE option in your kernel config
file and is not turned on by default.

Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches. The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes. Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header. This
hack will do until then. (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'. `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.

Make good on my promise to finally clean up the config clobbering.
If you invoke config with the `-n' flag or have NO_CONFIG_CLOBBER in
your environment, config will behave the same way it used to. This is
now _documented_ as well. Rip out all the CONFIG_DONT_CLOBBER cruft;
some of it wasn't even correct anyway.
