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.

51c1297a48 Allow one to specify a second parameter to the machine line. This
allows us to specify the machine_arch as well as machine.  If
specified then a second link will be made, similar to machine, from
$MACHINE_ARCH to $S/$MACHINE_ARCH/include.

This is for ports where MACHINE != MACHINE_ARCH (pc98 today, others in
the future?).

5e06480c9f Introduce an "include" directive. It takes one argument, a filename
to be included into this one.  This works the same way as #include
does in C; as far as the user is concerned, the included file is
inlined into the current one.

Since config(8) is no longer limited to working on one user-supplied
file, printing just a line number in an error message is not
sufficient.  The new global variable yyfile represents the file
currently being parsed, and must be printed as well.

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.

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.

2005b07aa8 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.
