Buffers run through copy-on-write are marked B_COWDONE. This condition
is valid until the buffer has run through bwrite() and gets cleared from
biodone().

to remove the frobbing that drivers must do in the hci_unit structure.
- driver provides a static const interface descriptor
- hci_unit is allocated by hci_attach() rather than part of softc
- statistics are compiled by driver and provided on request
- driver provides output methods and is responsible for output queue
- stack provides input methods and is responsible for input queue
- mutex is used to arbitrate device queue access
active development and its ABI (and possibly API) may change between
NetBSD versions.
This is critical to, for example, LKMs, where there might be a case of them
being built using one version of the ABI and used on system with another.
The main concern for "ABI" here is the set of KAUTH_* actions and requests
that is (for now) an enum. This note is likely to be removed as kauth(9)
is stablized -- hopefully before NetBSD 5.0.

While it's true that it's part of the traditional 4.4BSD security model,
there may come a time where a different "primary" security model used for
fine-grained privileges (ie., splitting root's responsibilities to various
privileges that can be assigned) may want to still have a securelevel
setting.
Idea from Daniel Carosone:

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).
sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.
The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).
Update all users and documentation to reflect these changes.

- Introduce sme_class into the sysmon_envsys struct to specify a
class; currently there are two classes: SME_CLASS_ACADAPTER and
SME_CLASS_BATTERY.
- Add a new envsys event: PENVSYS_EVENT_LOW_POWER that is reached when
all SME_CLASS_BATTERY devices are in CRITICAL/LOW state and there's not
any SME_CLASS_ACADAPTER connected.
- Add the 'low-power' event into the sensor_battery script that will
shutdown the system gracefully via 'shutdown -p'. If powerd(8) is
not running, cpu_reboot(9) with RB_POWERDOWN is used.
- Make acpiacad(4) a SME_CLASS_ACADAPTER device and acpibat(4) a
SME_CLASS_BATTERY device.
Update the documentation accordingly to these changes.
- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.
