hw.power, machdep.lidaction, machdep.pwraction for macppc

I can now use the power button to power off my macppcs running
OpenBSD. The new sysctls machdep.lidaction and machdep.pwraction act
like acpibtn(4), but we are missing code to suspend or hibernate a
macppc. Small kernels (bsd.rd) continue to ignore the power button.

adb(4) sends an environment interrupt when I unplug my PowerBook's AC
or close its lid. Rename PMU_INT_WAKEUP to PMU_INT_ENVIRONMENT like
other BSDs and Linux. Handle PMU_ENV_LID_CLOSED as a lid sensor and
PMU_ENV_AC_POWER by setting sysctl hw.power. Power buttons can either
use PMU_ENV_POWER_BUTTON or go through akbd(4); handle both kinds of
power buttons in the same way. Other models of macppc, with different
power buttons or lids, might not work yet. The lid sensor looks like,

$ sysctl hw.sensors
hw.sensors.adb0.indicator0=On (lid open)

kettenis@ warned against calling prsignal() from interrupt context,
and pointed me to task_add(9).

Define PMU_ADB_CMD and PMU_INT_ACK

Taking these definitions from NetBSD's pm_direct.h; most PMU_*
commands have the same names in the BSDs and Linux.

Correct yo-yo shutdowns:
Apparently some machines don't detect a clean (i.e. software initiated)
shutdown; and ignore the 'wake on AC loss' bit, meaning they wake up
immediatly after being told to shutdown e.g. via shutdown -hp.

So now we continue preserve the wake on AC loss behaivour, howerver if we
initiate a clean shutdown we clear this bit so that it the machine does not
immediately power back up again.

ok kettenis@

Add cuda_fileserver_mode() and pmu_fileserver_mode() that enable the wake
on AC loss feature of the power management IC. Make this the default
behaviour when booting OpenBSD from now on.

This will only affect machines that have the power suddenly cut, Performing
a shutdown requesting power down will clear this mode and its then possible
to remove the power cord, and plug it back in without the machine comming
back on automatically.

ok kettenis, drahn.

On via-pmu systems, check whether the firmware has found adb devices on the
bus to decide whether to go the long way or not when resetting the bus.
Fixes the long delay probe on Mac Mini. Tested by various.

Expect PMU_INT_SNDBRT while resetting the adb bus; although this brings the
long probe delay on the Mac Mini, this is necessary for reliable adb device
detection on several PowerBook families.

Factorize akbd and ams drivers between mac68k and macppc; while there, start
moving out common adb code as well, and merge adb_direct.c into adb.c to
simplify external header files.

No functional change; more cleanups to come.

Remove orphaned adb/pmu stuff; ok hshoexer@ kettenis@

Just poll for PMU_INT_ADB_AUTO and PMU_INT_ADB interrupts when resetting
the device, should fix a huge delay attaching adb(4) on some boxes,
