Implement new event timers infrastructure. It provides unified APIs for
writing event timer drivers, for choosing best possible drivers by machine
independent code and for operating them to supply kernel with hardclock(),
statclock() and profclock() events in unified fashion on various hardware.

Infrastructure provides support for both per-CPU (independent for every CPU
core) and global timers in periodic and one-shot modes. MI management code
at this moment uses only periodic mode, but one-shot mode use planned for
later, as part of tickless kernel project.

For this moment infrastructure used on i386 and amd64 architectures. Other
archs are welcome to follow, while their current operation should not be
affected.

This patch updates existing drivers (i8254, RTC and LAPIC) for the new
order, and adds event timers support into the HPET driver. These drivers
have different capabilities:
 LAPIC - per-CPU timer, supports periodic and one-shot operation, may
freeze in C3 state, calibrated on first use, so may be not exactly precise.
 HPET - depending on hardware can work as per-CPU or global, supports
periodic and one-shot operation, usually provides several event timers.
 i8254 - global, limited to periodic mode, because same hardware used also
as time counter.
 RTC - global, supports only periodic mode, set of frequencies in Hz
limited by powers of 2.

Depending on hardware capabilities, drivers preferred in following orders,
either LAPIC, HPETs, i8254, RTC or HPETs, LAPIC, i8254, RTC.
User may explicitly specify wanted timers via loader tunables or sysctls:
kern.eventtimer.timer1 and kern.eventtimer.timer2.
If requested driver is unavailable or unoperational, system will try to
replace it. If no more timers available or "NONE" specified for second,
system will operate using only one timer, multiplying it's frequency by few
times and uing respective dividers to honor hz, stathz and profhz values,
set during initial setup.

- Merge savectx2() with savectx() and struct xpcb with struct pcb. [1]
savectx() is only used for panic dump (dumppcb) and kdb (stoppcbs).  Thus,
saving additional information does not hurt and it may be even beneficial.
Unfortunately, struct pcb has grown larger to accommodate more data.
Move 512-byte long pcb_user_save to the end of struct pcb while I am here.
- savectx() now saves FPU state unconditionally and copy it to the PCB of
FPU thread if necessary.  This gives panic dump and kdb a chance to take
a look at the current FPU state even if the FPU is "supposedly" not used.
- Resuming CPU now unconditionally reinitializes FPU.  If the saved FPU
state was irrelevant, it could be in an unknown state.

Several improvements to HPET driver:
 - Add special check for case when time expires before being programmed.
This fixes interrupt loss and respectively timer death on attempt to
program very short interval. Increase minimal supported period to more
realistic value.
 - Add support for hint.hpet.X.allowed_irqs tunable, allowing manually
specify which interrupts driver allowed to use. Unluckily, many BIOSes
program wrong allowed interrupts mask, so driver tries to stay on safe
side by not using unshareable ISA IRQs. This option gives control over
this limitation, allowing more per-CPU timers to be provided, when FSB
interrupts are not supported. Value of this tunable is bitmask.
 - Do not use regular interrupts on virtual machines. QEMU and VirtualBox
do not support them properly, that may cause problems. Stay safe by default.
Same time both QEMU and VirtualBox work fine in legacy_route mode.
VirtualBox also works fine if manually specify allowed ISA IRQs with above.

Refactor timer management code with priority to one-shot operation mode.
The main goal of this is to generate timer interrupts only when there is
some work to do. When CPU is busy interrupts are generating at full rate
of hz + stathz to fullfill scheduler and timekeeping requirements. But
when CPU is idle, only minimum set of interrupts (down to 8 interrupts per
second per CPU now), needed to handle scheduled callouts is executed.
This allows significantly increase idle CPU sleep time, increasing effect
of static power-saving technologies. Also it should reduce host CPU load
on virtualized systems, when guest system is idle.

There is set of tunables, also available as writable sysctls, allowing to
control wanted event timer subsystem behavior:
  kern.eventtimer.timer - allows to choose event timer hardware to use.
On x86 there is up to 4 different kinds of timers. Depending on whether
chosen timer is per-CPU, behavior of other options slightly differs.
  kern.eventtimer.periodic - allows to choose periodic and one-shot
operation mode. In periodic mode, current timer hardware taken as the only
source of time for time events. This mode is quite alike to previous kernel
behavior. One-shot mode instead uses currently selected time counter
hardware to schedule all needed events one by one and program timer to
generate interrupt exactly in specified time. Default value depends of
chosen timer capabilities, but one-shot mode is preferred, until other is
forced by user or hardware.
  kern.eventtimer.singlemul - in periodic mode specifies how much times
higher timer frequency should be, to not strictly alias hardclock() and
statclock() events. Default values are 2 and 4, but could be reduced to 1
if extra interrupts are unwanted.
  kern.eventtimer.idletick - makes each CPU to receive every timer interrupt
independently of whether they busy or not. By default this options is
disabled. If chosen timer is per-CPU and runs in periodic mode, this option
has no effect - all interrupts are generating.

As soon as this patch modifies cpu_idle() on some platforms, I have also
refactored one on x86. Now it makes use of MONITOR/MWAIT instrunctions
(if supported) under high sleep/wakeup rate, as fast alternative to other
methods. It allows SMP scheduler to wake up sleeping CPUs much faster
without using IPI, significantly increasing performance on some highly
task-switching loads.

Introduce a new tunable 'hw.pci.do_power_suspend'.  This tunable lets you
avoid PCI power state transition from D0 to D3 for suspending case.  Default
is 1 or enabled.

Add two new loader tunables 'hw.acpi.install_interface' and
'hw.acpi.remove_interface'.  hw.acpi.install_interface lets you install new
interfaces.  Conversely, hw.acpi.remove_interface lets you remove OS
interfaces from the pre-defined list in ACPICA.  For example,

	hw.acpi.install_interface="FreeBSD"

lets _OSI("FreeBSD") method to return 0xffffffff (or success) and

	hw.acpi.remove_interface="Windows 2009"

lets _OSI("Windows 2009") method to return zero (or failure).  Both are
comma-separated lists and leading white spaces are ignored.  For example,
the following examples are valid:

	hw.acpi.install_interface="Linux, FreeBSD"
	hw.acpi.remove_interface="Windows 2006, Windows 2006.1"

Adjust a comment to clarify why \_SB_ and \_TZ_ are defined as device type
in ACPICA.  Reshuffle the code a bit to make sure this kludge only applies
to these two specical cases and to make it cleaner.

Fix a use-after-free bug for extended IRQ resource[1].  When _PRS buffer is
copied as a template for _SRS, a string pointer for descriptor name is also
copied and it becomes stale as soon as it gets de-allocated[2].  Now _CRS is
used as a template for _SRS as ACPI specification suggests if it is usable.
The template from _PRS is still utilized but only when _CRS is not available
or broken.  To avoid use-after-free the problem in this case, however, only
mandatory fields are copied, optional data is removed, and structure length
is adjusted accordingly.

Make APM emulation look more closer to its origin.  Use device_get_softc(9)
instead of hardcoding acpi(4) unit number as we have device_t for it.
