thorpej ea4d1b7ea1 Rather than using a separate "class" keyword, treat device classes like
special attributes.  From Chris Demetriou.

thorpej bc1733bc88 Add code to emit the cfdriver structures into ioconf.c. This requires
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.

thorpej 9fec93804a Changes to config(8) to support dump configuration in the wake of the
new swap system.  The dump specification syntax is now more flexible,
and supports constructs like the following:

config netbsd root on ? type ? dumps on ?
	- wildcarded root, fstype, and dump device

config netbsd root on ? type ffs dumps on sd0b
	- wildcarded root, ffs root fs, always dump on sd0b

config netbsd root on de0 type nfs dumps on wd0b
	- mount an nfs root using de0, and write kernel crash dumps
	  to wd0b

Also, garbage-collect some now unused code, now that swap configuration
is no longer handled by config(8).

thorpej 267e8357fc Implement an unfortunate, and temporary, kludge to address the problem
reported in PR #3668 from maximum entropy <entropy@tanstaafl.bernstein.com>.

The problem: The unit number is not being conveyed to the configuration
crosscheck with root is a network interface; the device number is set
to NODEV, which sets up the (correct) defaults for swap/dump devices.
We can't change NODEV to a unit number, as the PR's patch suggests, as
this breaks the swap/dump defaults.  Rewriting that code is not really
justified, since it's soon to be obsoleted.

The kludge: add an "nv_ifunit" member to struct nvlist, which convey's
a network interface's unit number to the crosscheck routine.  It's not
pretty, but it's not terribly invasive, and can be garbage-collected
easily when the swap/dump goo is obsoleted.

leo 0b28c6c0b1 Don't dump when a non-existent root device is specified. (missed a

jtk 0f6d8d88b8 Add hash table walking functions to emit manifest constants for locator
offsets within cf->cf_loc[].
Also include locator names as strings in ioconf.c.

Still to do: wire the locator names into the cfdata.

thorpej 07c71aa7f7 Implement new grammar and semantics for specifying file systems
and the root device:

- New "file-system" keyword is used to configure file systems into
  the kernel.
- New way of specifying root device, which allows root file system
  type to always be specified.  Examples:

	config gennetbsd swap generic
	config sdnetbsd root on sd0a swap on sd0b
	config nfsnetbsd root on nfs

  are replaced by:

	config gennetbsd root on ? type ?
	config sdnetbsd root on sd0a type ffs swap on sd0b
	config nfsnetbsd root on ? type nfs
	config lenetbsd root on le0 type nfs

  Note that specific network interfaces may now be specified as
  the root device.
- swapgeneric.c is no longer used; generate a swap*.c file for each
  "config" line in the kernel configuration file.

cgd 315f091f18 fix (apparently long-standing) bug which prevented devices from attaching
to interface attributes on a device other than the interface attribute that
the device was named the same as, if that one was there.

cgd 2dd7a7984c Fix PR 2218. As noted (both in mail from me included in the PR, and
in XXX-marked comments in the recent attachment changes), this was a
long-standing bug in config.

The problem: If a device is attached to a device via an attribute exported
by that device (i.e. foo* at bar0, where 'bar' exports an attribute that
'foo' attaches to), but the device attached to is not present in the
kernel configuration file, AND another device which exports an attribute
that 'foo' attaches to _is_ present (e.g. a device baz0, if one could
specify 'foo0 at baz0'), then: the configuration file will (incorrectly)
be accepted by config, and the resulting ioconf.c will include a bogus
cfdata entry for the device (in the example, 'foo*').  This typically
causes the resulting kernel to crash during autoconfiguration.

The solution: Be much more careful about keeping track of where a device
was attached, and, in particular, if a device was attached to another device,
_always_ keep track of what device it was attached to.  Then, when
cross-checking, if the attached-to device isn't present, give up and do not
check attributes.  Also, document the process much more thoroughly.

cgd 95f205f10c fix bogon in device attachment name checking. the same rules should be
used for checking device attachment names as are used for device name
checking, because device names can be used as attachment names.  (Actually,
less strict rules could be used, but there's little point in that.)  This
was not a mistake of design, this was just a mistake; i misunderstood
the devbase name checking code.

thorpej cb6211e540 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
