30f94bb497 Fix a bug introduced by DEFAULTS feature. When the config file
doesn't exist, we make a directory and then say "oops, that file isn't
there" leaving the directory behind.  Add a stat for the config file
so that we detect this before making the directory.  This is
semi-lame, but less lame than having this bug.

91998fc549 Spring forward into the late 1970's by following item 5 in the yacc
manual's Appendix D ("Old Features Supported but not Encouraged") in
the Seventh Edition Unix Programmer's Manual (January, 1979) by
retiring the " = {" method of of action specification in favor of a
plain "{".  It is no longer necessary for this bootstrap program to
be compatible with 6th Edition systems.  Some yaccs in the wild do not
support this old syntax any more, and compatibility with those systems
is more important these days (as there are easily 7 orders of magnitude
more of them than real v6 systems today).

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.

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.

Remember about tricky cases, where options contain unfriendly characters,

breakage was caused by SC_CUT_SEPCHARS options.

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.

Don't keep duplicate files in the files list just to

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.
