is declared at most once.
* Do option dependency across all def{opt,param, flag}.
* Make the default value of otherwise-unspecified defopt's be 1,
for consistency with non-defopt'ed options.
* Wrap an abstraction layer (macros) around tests for defopt, filesystem,
defparam, etc. to catch outdated defopt-vs-filesystem tests.
* machinery for nonfatal warnings.
* new backend config-file keywords:
defparam -- like defopt, but each defparam option is required
to have a value when configured via "options".
defflag -- like defopt, but defflag options may not have a value.
Also, on "option FOO", a needs-count style flag
(NFOO, either 0 or 1) is emitted to the .h file.
* Warn about old-style options that aren't defined via def{opt,param,flag}
and which are added to IDENT. (These behave subtly differently
to defopt options when no explicit value is given.)
a change to the config grammar, to specify a device's class (i.e. DV_xxx)
like:
device sd class disk: ...
Also emit an ioconf.h, which contains extern declarations of the
cfdriver structures.
While I'm here, add support for specifying multiple options per defopt
line, as well as specifying the file name in which the options will
appear.
defopt foo bar baz
generates "opt_foo.h", "opt_bar.h", and "opt_baz.h"
defopt opt_mumble.h foo bar baz
generates "opt_mumble.h" which contains all three options.
Also, clean up and fix some bugs in the code that generates header files.
be included in object dependencies. config(8) is told to generate
a header for a particular option with the new "defopt" keyword, used
in the files.* system description files. Options that are placed in
header files are not given -D... cpp flags.
This approach allows options to be turned into headers incrementally,
rather than all at once, and allows for non-header options, as well.

Also, remove special case for i386 in vector handling, although this code isn't
actually used any more.
wouldn't". this is overridden by (and is a subset of "device-driver".
if you have a "standard" file, you can also do: "standard foo needs-count"
to get a foo.h file. (for the hp300 stuff)
and files.kernel has now been completely replaced.
features supported: not nearly as broken as the stuff before
expression support for dependencies
support for 'requires'
no longer generates lots of stupid unnecessary .h files
broke lots of broken stuff, and forced fixing it.

added '-k' option for continue even after error
