It is possible to overflow the (low 32bit) HPET counter between hpet_attach
and TSC calibration if the boot is delayed for more than ~430 seconds (or
less, depending on HPET frequency). The result is a badly misconfigured
timecounter.

Change the measurement interval to ~1e6 HPET ticks (<100ms) during
the calibration to avoid the overflow. This introduces an error of
1ppm, compared to the previous unspecified but typical error of 0.1ppm.
But this is still much less than the guaranteed maximum frequency drift
of the HPET counter itself, which is 500ppm.

Fix the TSC timecounter (on the systems I have access to):

- Make the early i8254-based calculation of frequency a bit more accurate.

- Keep track of how far the HPET & TSC advance between HPET attach and
  secondary CPU boot, and use to compute an accurate value before attaching
  the timecounter.  Initial idea from joerg@.

- When determining skew and drift between CPUs, make each measurement 1000
  times and pick the lowest observed value.  Increase the error threshold to
  1000 clock cycles.

- Use the frequency computed on the boot CPU for secondary CPUs too.

- Remove cpu_counter_serializing().

correct 14318180Hz, instead of 14318179Hz, which seems a bit odd.

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.

Refactor PNP API:
- Make suspend/resume directly a device functionality. It consists of
  three layers (class logic, device logic, bus logic), all of them being
  optional. This replaces D0/D3 transitions.
- device_is_active returns true if the device was not disabled and was
  not suspended (even partially), device_is_enabled returns true if the
  device was enabled.
- Change pnp_global_transition into pnp_system_suspend and
  pnp_system_resume. Before running any suspend/resume handlers, check
  that all currently attached devices support power management and bail
  out otherwise. The latter is not done for the shutdown/panic case.
- Make the former bus-specific generic network handlers a class handler.
- Make PNP message like volume up/down/toogle PNP events. Each device
  can register what events they are interested in and whether the handler
  should be global or not.
- Introduce device_active API for devices to mark themselve in use from
  either the system or the device. Use this to implement the idle handling
  for audio and input devices. This is intended to replace most ad-hoc
  watchdogs as well.
- Fix somes situations in which audio resume would lose mixer settings.
- Make USB host controllers better deal with suspend in the light of
  shared interrupts.
- Flush filesystem cache on suspend.
- Flush disk caches on suspend. Put ATA disks into standby on suspend as
  well.
- Adopt drivers to use the new PNP API.
- Fix a critical bug in the generic cardbus layer that made D0->D3
  break.
- Fix ral(4) to set if_stop.
- Convert cbb(4) to the new PNP API.
- Apply the PCI Express SCI fix on resume again.
