Previously it didn't honor parent dma tag's restrictions such that
an invalid dma segment could be passed to device. The driver for the
device may panic in sanity check routine for the dma segment or may
produce unexpected results. I have no idea how it could ever have
worked before.

used to return PAGE_SIZE without respect to restrictions of a DMA tag.
This affected all of the busdma load functions that use
_bus_dmamap_loader_buffer() as their back-end.

Improvements:
* /etc/rc.suspend,rc.resume are always run, no matter the source of the
suspend request (user or kernel, apm or acpi)
* suspend now requires positive user acknowledgement. If a user program
wants to cancel the suspend, they can. If one of the user programs
hangs or doesn't respond within 10 seconds, the system suspends anyway.
* /dev/apm is clonable, allowing multiple listeners for suspend events.
In the future, xorg-server can use this to be informed about suspend
even if there are other listeners (i.e. apmd).
Changes:
* Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the
process of suspending by notifying all listeners. acpi is monitored by
devd(8) and /dev/apm listener(s) are also counted. Users register their
approval or disapproval via Ack. If anyone disapproves, suspend is vetoed.
* Old user programs or kernel modules that used SETSLPSTATE continue to
work. A message is printed once that this interface is deprecated.
* acpiconf gains the -k flag to ack the suspend request. This flag is
undocumented on purpose since it's only used by /etc/rc.suspend. It is
not intended to be a permanent change and will be removed once a better
power API is implemented.
* S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z.
This restores previous behavior of halt/shutdown -p being the interface.
* Miscellaneous improvements to error reporting

o Consistently use device_foo_t and bus_foo_t for functions implementing
device_foo and bus_foo respectively. Adjust those routines that were wrong
(we should do this throughout the tree).
o make all the modules depend on usb. Otherwise these modules won't
load.
o ucycom doesn't need usb_port.h
o Minor unifdefing
o uhub, umass, ums, urio, uscanner conversion complete.
o ukbd: Remove the NO_SET_PROTO quirk (fixes a PR 77940). NetBSD removed
their check and setting the proto a long time ago.
o umodem panic fixed. UQ_ASSUME_CM_OVER_DATA quirk removed because I've never
seen a umodem that needed this rejection for proection (this gets rid of
~20% of the quirks).

Older drivers that do not wish to convert to the native API (which
will work with both 6.x and 7.x) can simply include
<dev/usb/usb_port.h>. Drivers in the tree shouldn't these macros,
unless they actually work on other OSes and are actively maintained.

mouse pointer instead of a 8 x 16 one so device drivers don't
need to bring there own one there and in gfb_mouse() (ab)use
the pixel_mask argument of putm() to pass along on/off info as
erasing the mouse cursor image by redrawing the text underneath
doesn't work as we use hardware cursors on sparc64.
