obsolete defflag <option> [, <option> [, ...]]
obsolete defparam <option> [, <option> [, ...]]
The two statements actually do the same thing (there could be only one),
but it makes things less cryptic that way. The optional ": deps" part of
a 'defflag' or 'defparam' still has to be dropped when it gets obsoleted.
When the user has 'options OBSOLETE_OPTION' in his configuration file, it
is ignored (that is, opt_*.h files are generated as if it wasn't there),
and the user gets a warning about it.
Bump version to 20060525.
When someone first uses that syntax in the tree, a "version 20060525"
statement should be added before its occurrence, preferably at the top
of sys/conf/files.

made a device its own parent. Add a test that checks that and stop looping
in that special case (after all, everything is already being handled by the
parent instance).

already (one of its instances has been changed), and we have made no change
on any of the instances.
Previously, it stopped as soon as it detected the device had been seen.
While all the instances of the device at stake were eventually seen, the
same wasn't true for its children...
Fixes hpcmips's GENERIC.

- Record the position in the config file of device instances so it is
possible to tell if a device instance was declared before or after its
parent's removal.
E.g.:
child* at parent?
no parent
will have the child instance ignored as an explicit orphan, while
no parent
child* at parent?
will error out because now the child instance is a real orphan.
That let the POSTPONED_ORPHAN regression test pass.
o Rework do_kill_orphans() to use that information and mark explicitely
orphaned devices (i.e., the ones whose missing ancestor has been
negated)
o Make a distinction between erroneous orphans and explicit orphans.
Error out on the former, ignore the later (but print a warning when -v
is used)
Yes, now config(1) will actually stop if you comment out a parent. That
should help people still hoping adjustkernel is relevant these days :)
track of instances attaching at root, and walk down the tree of active
device instances. Then, all instances that are not marked active are
found as orphans.
Doing it that way allows us to simply ignore orphan devices, instead of
warning about them and still keep them in the configuration. Now, orphaned
instances are considered as never having existed.
In the end, this allows 'no <device> at <attachment>' to be much more
efficient, as the user doesn't have to negate all descendents of the
instance s/he actually wants to negate. Warnings are still emitted,
though.
While there, make official a side-effect of the previous lack of action
against orphaned instances: config(1) used to warn about instances that
attach at a numbered device when no instance of that device with that
number existed, even though there was a starred instance of the device.
E.g. (provided by Alan Barrett):
pciide* at pci? dev ? function ? flags 0x0000
wdc0 at isa? port 0x1f0 irq 14 flags 0x00
wdc1 at isa? port 0x170 irq 15 flags 0x00
atabus* at ata?
wd0 at atabus0 drive 0
With this commit, config(1) will no longer warn about 'wd0 at atabus0'.
