pmf(9): *_child_register never fails.  Make it return void.

No kernel bump because this isn't documented or used in any modules,
only in dev/pci/pci.c and dev/cardbus/cardbus.c which are as far as I
know always statically linked into the kernel.

The next change, however, will require a revbump -- to make
pmf_device_register return void so we can prune vast swaths of dead
error branches.

kern: device_pmf_driver_register never fails, so make it return void.

No ABI bump despite change to device.h because this is used only
inside autoconf.

sys: Split struct device into a private device_impl.h.

Include this only inside autoconf itself, and a few files that abuse
autoconf in ways I can't confidently make easy fixes for.

XXX kernel ABI change requires bump -- no more use of struct device
internals allowed, previously done by some drivers

Back out fix for kern_pmf.c calling a null if_stop and apply a fix
suggested by Jared McNeill which sets if_stop to a stub function
which means that more than just the pmf is protected from the NULL call.

Prevent kernel panic on sleep if network interface driver does not
have if_stop defined.  This is a common problem with usb adaptors.
This is a temporary fix, the printf needs to be converted to an
assert once the drivers are cleaned up.

in pmf_system_shutdown(), don't do anything if we're panicing.
this prevents a hang trying to shut down other CPUs on x86,
and in general we could be called in any context from a panic
so it's best to skip unnecessary operations in that case.

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

In pmf(9), improve the implementation of device self-suspension
and make suspension by self, by drvctl(8), and by ACPI system sleep
play nice together.  Start solidifying some temporary API changes.

1. Extract a new header file, <sys/device_if.h>, from <sys/device.h> and
   #include it from <sys/pmf.h> instead of <sys/device.h> to break the
   circular dependency between <sys/device.h> and <sys/pmf.h>.

2. Introduce pmf_qual_t, an aggregate of qualifications on a PMF
   suspend/resume call.  Start to replace instances of PMF_FN_PROTO,
   PMF_FN_ARGS, et cetera, with a pmf_qual_t.

3. Introduce the notion of a "suspensor," an entity that holds a
   device in suspension.  More than one suspensor may hold a device
   at once.  A device stays suspended as long as at least one
   suspensor holds it.  A device resumes when the last suspensor
   releases it.

   Currently, the kernel defines three suspensors,

   3a the system-suspensor: for system suspension, initiated
      by 'sysctl -w machdep.sleep_state=3', by lid closure, by
      power-button press, et cetera,

   3b the drvctl-suspensor: for device suspension by /dev/drvctl
      ioctl, e.g., drvctl -S sip0.

   3c the system self-suspensor: for device drivers that suspend
      themselves and their children.  Several drivers for network
      interfaces put the network device to sleep while it is not
      administratively up, that is, after the kernel calls if_stop(,
      1).  The self-suspensor should not be used directly.  See
      the description of suspensor delegates, below.

   A suspensor can have one or more "delegates".  A suspensor can
   release devices that its delegates hold suspended.  Right now,
   only the system self-suspensor has delegates.  For each device
   that a self-suspending driver attaches, it creates the device's
   self-suspensor, a delegate of the system self-suspensor.

   Suspensors stop a system-wide suspend/resume cycle from waking
   devices that the operator put to sleep with drvctl before the cycle.
   They also help self-suspension to work more simply, safely, and in
   accord with expectations.

4. Add the notion of device activation level, devact_level_t,
   and a routine for checking the current activation level,
   device_activation().  Current activation levels are DEVACT_LEVEL_BUS,
   DEVACT_LEVEL_DRIVER, and DEVACT_LEVEL_CLASS, which respectively
   indicate that the device's bus is active, that the bus and device are
   active, and that the bus, device, and the functions of the device's
   class (network, audio) are active.

   Suspend/resume calls can be qualified with a devact_level_t.
   The power-management framework treats a devact_level_t that
   qualifies a device suspension as the device's current activation
   level; it only runs hooks to reduce the activation level from
   the presumed current level to the fully suspended state.  The
   framework treats a devact_level_t qualifying device resumption
   as the target activation level; it only runs hooks to raise the
   activation level to the target.

5. Use pmf_qual_t, devact_level_t, and self-suspensors in several
   drivers.

6. Temporarily add an unused power-management workqueue that I will
   remove or replace, soon.

pmf_event_inject(9) may be called from interrupt context, so we
must not allocate a pmf_event_workitem_t using kmem_alloc(9).  Use
pool_cache(9), instead, because it is safe in interrupt context.
Thanks, rmind@, for catching the problem and suggesting the solution.

Switch to kmem(9).

(void *)pew is one way to get a struct work *, but let's
write&pew->pew_work, instead.  It is more defensive and persuasive.

Make miscellaneous changes in support of tearing down arbitrary
stacks of filesystems and devices during shutdown:

1 Move struct shutdown_state, shutdown_first(), and shutdown_next(),
  from kern_pmf.c to subr_autoconf.c.  Rename detach_all() to
  config_detach_all(), and move it from kern_pmf.c to subr_autoconf.c.
  Export all of those routines.

2 In pmf_system_shutdown(), do not suspend user process scheduling, and
  do not detach all devices: I am going to do that in cpu_reboot(),
  instead.  (Soon I will do it in an MI cpu_reboot() routine.)  Do still
  call PMF shutdown hooks.

3 In config_detach(), add a DIAGNOSTIC assertion: if we're exiting
  config_detach() at the bottom, alldevs_nwrite had better not be 0,
  because config_detach() is a writer of the device list.

4 In deviter_release(), check to see if we're iterating the device list
  for reading, *first*, and if so, decrease the number of readers.  Used
  to be that if we happened to be reading during shutdown, we ran the
  shutdown branch.  Thus the number of writers reached 0, the number
  of readers remained > 0, and no writer could iterate again.  Under
  certain circumstances that would cause a hang during shutdown.

Do not interleave device detachment with device shutdown.  Instead, try
over and over to detach all of the devices.  Stop when we cannot detach
even a single device in a cycle.  Call shutdown hooks on all of the
devices that remain attached.

This is another step toward the detach/unmount cycle that will help us
tear down arbitrary stacks of filesystems, ccd(4), raid(4), and vnd(4).

During shutdown, detach devices in an orderly fashion.

Call the detach routine for every device in the device tree, starting
with the leaves and moving toward the root, expecting that each
(pseudo-)device driver will use the opportunity to gracefully commit
outstandings transactions to the underlying (pseudo-)device and to
relinquish control of the hardware to the system BIOS.

Detaching devices is not suitable for every shutdown: in an emergency,
or if the system state is inconsistent, we should resort to a fast,
simple shutdown that uses only the pmf(9) shutdown hooks and the
(deprecated) shutdownhooks.  For now, if the flag RB_NOSYNC is set in
boothowto, opt for the fast, simple shutdown.

Add a device flag, DVF_DETACH_SHUTDOWN, that indicates by its presence
that it is safe to detach a device during shutdown.  Introduce macros
CFATTACH_DECL3() and CFATTACH_DECL3_NEW() for creating autoconf
attachments with default device flags.  Add DVF_DETACH_SHUTDOWN
to configuration attachments for atabus(4), atw(4) at cardbus(4),
cardbus(4), cardslot(4), com(4) at isa(4), elanpar(4), elanpex(4),
elansc(4), gpio(4), npx(4) at isa(4), nsphyter(4), pci(4), pcib(4),
pcmcia(4), ppb(4), sip(4), wd(4), and wdc(4) at isa(4).

Add a device-detachment "reason" flag, DETACH_SHUTDOWN, that tells the
autoconf code and a device driver that the reason for detachment is
system shutdown.

Add a sysctl, kern.detachall, that tells the system to try to detach
every device at shutdown, regardless of any device's DVF_DETACH_SHUTDOWN
flag.  The default for kern.detachall is 0.  SET IT TO 1, PLEASE, TO
HELP TEST AND DEBUG DEVICE DETACHMENT AT SHUTDOWN.

This is a work in progress.  In future work, I aim to treat
pseudo-devices more thoroughly, and to gracefully tear down a stack of
(pseudo-)disk drivers and filesystems, including cgd(4), vnd(4), and
raid(4) instances at shutdown.

Also commit some changes that are not easily untangled from the rest:

(1) begin to simplify device_t locking: rename struct pmf_private to
device_lock, and incorporate device_lock into struct device.

(2) #include <sys/device.h> in sys/pmf.h in order to get some
definitions that it needs.  Stop unnecessarily #including <sys/device.h>
in sys/arch/x86/include/pic.h to keep the amd64, xen, and i386 releases
building.

Use device_t and its accessors throughout.  Use aprint_*_dev().

Improve PMF-ability.

        Add a 'flags' argument to suspend/resume handlers and
        callers such as pmf_system_suspend().

        Define a flag, PMF_F_SELF, which indicates to PMF that a
        device is suspending/resuming itself.  Add helper routines,
        pmf_device_suspend_self(dev) and pmf_device_resume_self(dev),
        that call pmf_device_suspend(dev, PMF_F_SELF) and
        pmf_device_resume(dev, PMF_F_SELF), respectively.  Use
        PMF_F_SELF to suspend/resume self in ath(4), audio(4),
        rtw(4), and sip(4).

        In ath(4) and in rtw(4), replace the icky sc_enable/sc_disable
        callbacks, provided by the bus front-end, with
        self-suspension/resumption.  Also, clean up the bus
        front-ends.  Make sure that the interrupt handler is
        disestablished during suspension.  Get rid of driver-private
        flags (e.g., RTW_F_ENABLED, ath_softc->sc_invalid); use
        device_is_active()/device_has_power() calls, instead.

        In the network-class suspend handler, call if_stop(, 0)
        instead of if_stop(, 1), because the latter is superfluous
        (bus- and driver-suspension hooks will 'disable' the NIC),
        and it may cause recursion.

        In the network-class resume handler, prevent infinite
        recursion through if_init() by getting out early if we are
        self-suspending (PMF_F_SELF).

rtw(4) improvements:

        Destroy rtw(4) callouts when we detach it.  Make rtw at
        pci detachable.  Print some more information with the "rx
        frame too long" warning.

Remove activate() methods:

        Get rid of rtw_activate() and ath_activate().  The device
        activate() methods are not good for much these days.

Make ath at cardbus resume with crypto functions intact:

        Introduce a boolean device property, "pmf-powerdown".  If
        pmf-powerdown is present and false, it indicates that a
        bus back-end should not remove power from a device.

        Honor this property in cardbus_child_suspend().

        Set this property to 'false' in ath_attach(), since removing
        power from an ath at cardbus seems to lobotomize the WPA
        crypto engine.  XXX Should the pmf-powerdown property
        propagate toward the root of the device tree?

Miscellaneous ath(4) changes:

        Warn if ath(4) tries to write crypto keys to suspended
        hardware.

        Reduce differences between FreeBSD and NetBSD in ath(4)
        multicast filter setup.

        Make ath_printrxbuf() print an rx descriptor's status &
        key index, to help debug crypto errors.

        Shorten a staircase in ath_ioctl().  Don't check for
        ieee80211_ioctl() return code ERESTART, it never happens.

Extend the pmf suspend/resume hooks by a shutdown method, so drivers
can register a shutdown handler explicitely.
Install a pci bus shutdown handler which disables bus master accesses
for all childs, so the drivers don't need to care.
This will hopefully be sufficient to replace the shutdownhooks
(together with the powerhooks). (It has been suggested to use some
general event notification framework for shutdown handlers, but there
might be cases where shutdown handlers must be run in an order following
the device hierarchy, which wouldn't be easy with event handlers
not tied to drivers.)

On system suspend, first get rid of the X server because it doesn't
respect the kernel device tree. (It is arguably ugly to special-case
wscons here, but as long as there is only one driver to be dealt with
it is not worth to introduce another set of hooks.)
Resume the X server at the end of resume, if everything went well.
Acquire the big KERNEL_LOCK before the device tree is walked on
suspend, until after the walk on resume. This is needed to avoid
device accesses by secondary CPUs, and it effectively keeps user
programs from interfering with the suspend process. This might be
revisited when all drivers are using private locks for MP-safeness
(but FreeBSD still does the same afaics).
It should be unnecessary now to switch secondary CPUs offline in
