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.

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?).

Kill count device support from config. I've changed the last few

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device. This broke things like the snd_emu10k1 device, which required
quotes to make it parse right. The no-longer-needed quotes have been
removed from NOTES, GENERIC etc. eg, I've removed the quotes from:
device snd_maestro
device "snd_maestro3"
device snd_mss

I believe everything will still compile and work after this.

Fixed spurious syntax errors for including files that don't begin with
a SEMICOLON token (a newline or semicolon, or one of these preceded
by a comment and/or whitespace). The input stream was switched too
early and the parser was expecting a SEMICOLON in the included file
instead of after the filename in the include directive.

Implemented "nooption" and "nomakeoption" config(8) tokens.
Fixed memory leak in the "nodevice" option implementation.

Use these instead of sed(1) in MD NOTES.

Use a single makefile (sys/conf/makeLINT.mk) to generate
LINT for all architectures. (Previous versions missed
the LINT dependency on Makefile, and i386 version also
missed the dependency on ${NOTES}.)

Fixed bugs in the previous NOTES conversion using the
"nodevice" token and sed(1):

- i386 LINT lost "device pst".

- pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD
options, and got needless DPT_* options.

- Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV
to sparc64 LINT so that it has a chance to config(8).

This basically returns us to where we were before.

Fixed the potential bug in rmopt().

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.

take your word for the 'machine' switch.
