driver(9): devsw_detach never fails.  Make it return void.

Prune a whole lotta dead branches as a result of this.  (Some logic
calling this is also wrong for other reasons; devsw_detach is final
-- you should never have any reason to decide to roll it back.  To be
cleaned up in subsequent commits...)

XXX kernel ABI change to devsw_detach signature requires bump

drvctl(4): If no ifattr is specified on rescan, rescan all of them.

No longer must you remember the magic `-a ata_hl' incantation when
you deign to `drvctl -r atabusN'.  It didn't actually do anything
anyway: atabus_rescan always rescans all ifattrs; same with
uhub_rescan and many others.

drvctl(4): Hold a deviter while issuing config_detach.

Otherwise another concurrent detach -- e.g., from concurrent drvctl
or from USB port disconnection -- can pull the device_t out from
under us.

XXX Need to do this for _every_ operation config_* operation on a
device_t; device_find_by_xname is just fundamentally broken because a
concurrent detach can pull the device_t rug out from under you.

We really need another mechanism for holding a weak reference to a
device, and temporarily getting a strong reference to it; abusing
deviter is a bit of a kludge, and doesn't work very well because it
doesn't properly trigger garbage collection of devices detached while
other concurrent deviters are pending.

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Instead of repeatedly typing the conditional initialization of the

I have not built every extant kernel so I have probably broken at

cdevsw/bdevsw entries so even if so I think we come out ahead.

If a multithreaded app closes an fd while another thread is blocked in
read/write/accept, then the expectation is that the blocked thread will
exit and the close complete.
Since only one fd is affected, but many fd can refer to the same file,
the close code can only request the fs code unblock with ERESTART.
Fixed for pipes and sockets, ERESTART will only be generated after such
a close - so there should be no change for other programs.
Also rename fo_abort() to fo_restart() (this used to be fo_drain()).
Fixes PR/26567

Rename fo_drain() to fo_abort(), 'drain' is used to mean 'wait for output
do drain' in many places, whereas fo_drain() was called in order to force
blocking read()/write() etc calls to return to userspace so that a close()
call from a different thread can complete.
In the sockets code comment out the broken code in the inner function,
it was being called from compat code.

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.

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.

Synchronize readers and writers of the device tree.

Add a device iterator object, deviter_t, and methods deviter_init(),
deviter_first(), and deviter_next() for visiting each device in
the device tree.

Take care not to re-shutdown a device in the event that the machine
panics during reboot and the operator types 'reboot' at the kernel
debugger prompt.

While I'm here, sprinkle PMF_FN_ARGS, PMF_FN_PROTO, et cetera.

The tricks done in device_foreach_child() still don't make it safe to use
by config_detach_children(), because the latter can work recursively
and remove any number of devices, so rewrite config_detach_children()
to restart list traversal after each call of config_detach(), and since
only one user of device_foreach_child() is left (in kern_drvctl.c),
and it is simpler to open-code the loop than to deal with callbacks,
just remove it.

- Add a new DRVCTLCOMMAND ioctl to /dev/drvctl.  This is a generic
  "execute a command" ioctl that takes a dictionary as an argument
  (specifying the command and arguments) and returns a dictionary
  with the results (error code, optional error message, optional
  result data).

- Define and implement a "get-properties" command for DRVCTLCOMMAND
  that returns the properties dictionary of the specified device.

- Add a -p flag to drvctl(8) to fetch and display the properties of
  the specified device.

This is a great example of how to use prop_dictionary_sendrecv_ioctl().
