c1f4dd9355 Fix some problems that affect multiple file inclusion. Bruce found
this bug and submitted these patches to dunstan@.  He sent them to me
to test, and I discovered they were needed for the atmel kernel config
files.  Since we were playing with them in the terminal room after the
developer's summit today, I thought I'd go ahead and commit them to
allow those folks that now have atmel hardware (thanks Andre) a chance
to try it out w/o my help.  Since dunstan@ is asleep right now, risk
stepping on his toes a little by going ahead and committing this
change.

kernels.

9e2f7513e1 Bump config(8) version and build requirement for config(8) to 600006. This
is caused by my latest changes to config(8). You're supposed to install new
config(8) in order to prevent yourself from seeing a warning about old
version of that tool.

You should configure the kernel with a new config(8) then.

ae7a150a68 This is loser's commit message:
Remember about tricky cases, where options contain unfriendly characters,
from the ANSI-C string point of view ('"' in this case). The x09 build
breakage was caused by SC_CUT_SEPCHARS options.

I did test this patch number of times; each time unprofessionally and
inappropriately.

744b947ef8 Improve INCLUDE_CONFIG_FILE support.
This change will let us to have full configuration of a running kernel
available in sysctl:

	sysctl -b kern.conftxt

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.

03349079fe The DEFAULTS changes caused the user specified config file to be opened
much later than before, and it is now after we do a mkdir ../compile/FILE.
As a result, if you do 'config DOESNOTEXIST', it now creates the directory
../config/DOESNOTEXIST.  It did not do that before.  If DEFAULTS does not
exist, it still fails early before any permanent changes.

This shameless hack restores the old behavior of ensuring the config file
actually exists before mkdiring its counterpart directory.

Now I can rmdir ../compile/D and it will stay dead, after my fingers keep
sabotaging me with 'config D<tab><enter>'.  (Some of my kernel names
started with D, which used to be 1-character unique and my fingers knew
this very well...)

ae54f5616d 600004 is a better new version than 700000 based on some future commits to
this file.  With ru@'s approval, change it to this version.  In this case we
had to bump the version because the old parser would choke on | in the new
'or' syntax and consider that a device.

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.

634e3a5c83 Add some rationale about when to bump and not bump the config version.
Clarify that it is not like the shlib versions, and not like param.h's
__FreeBSD_version/osreldate either.

When config(8) was actively changing a while back, the interface between
config and the build system (eg: /sys/conf/files.* and Makefile.*) was
changing rapidly.  configvers is a version number of that interface.

User specified config files do not have a version number.  The decision
about whether a user supplied config file is syntactically valid or not
belongs to the parser and sanity checks, not an arbitary number.

dfdbf9be00 Optionally include a DEFAULTS config file if it is present in the current
directory before the specified config file.  This is implemented by
opening DEFAULTS as stdin if it exists, and if so resetting stdin to the
actual config file when DEFAULTS is fully parsed via yywrap().  In short,
this lets us create DEFAULTS kernel configs in /sys/<arch>/conf that can
enable certain options or devices by default and allow users to disable
them via 'nooptions' or 'nodevice' rather than having to create kludge
NO_FOO options.
