59c82e8fd0 Add support for system power profiles; select "performance" when AC power
is available and "economy" when it is not.

6f69255b9f Add a new helper function for finding resources in resource buffers.
Move the ACPI generic battery code into a new file.

03b5e1982a Add ACPI subsystem mutex support, currently disabled. This implements
a private mutex we can use to wrap the ACPI subsystem proper.

c5ba0be495 Sync to my work in progress:
- Reorder the acpi_* functions in a sensible fashion
 - Add acpi_ForeachPackageObject and acpi_GetHandleInScope
 - Use the new debugging layer/level names
 - Implement most of the guts of the acpi_thermal module; passive cooling
   isn't there yet, but active cooling should work.
 - Implement power resource handling (acpi_powerres.c)

This compiles and mostly works, but my test coverage is small, so feedback
is welcome.

2a4ac806d7 - Updates for new constant naming in the ACPI CA 20010518 update.
- Use __func__ instead of __FUNCTION.
 - Support power-off to S3 or S5 (takawata)
 - Enable ACPI debugging earlier (with a sysinit)
 - Fix a deadlock in the EC code (takawata)
 - Improve arithmetic and reduce the risk of spurious wakeup in
   AcpiOsSleep.
 - Add AcpiOsGetThreadId.
 - Simplify mutex code (still disabled).

91467fc61d ACPI_NUMBER becomes ACPI_INTEGER. acpi_EvaluateNumber becomes
acpi_EvaluateInteger.

Use acpi_EvaluateInteger instead of doing things the hard way where
possible.

AcpiSetSystemSleepState (unofficial) becomes AcpiEnterSleepState.

Use the AcpiGbl_FADT pointer rather than searching for the FADT.

1d073b1d43 Add 3 new dynamic sysctl's to control the sleep states switched to on a
power button, sleep button, or lid close event.  The sysctl's use the
ACPI sleep state names S0, S1, S2, S3, S4, S4B, and S5.

0ae554237c - Convert a lot of homebrew debugging output to use the ACPI CA debugging
infrastructure.  It's not perfect, but it's a lot better than what
   we've been using so far.  The following rules apply to this:
    o BSD component names should be capitalised
    o Layer names should be taken from the non-CA set for now.  We
      may elect to add some new BSD-specific layers later.

 - Make it possible to turn off selective debugging flags or layers
   by listing them in debug.acpi.layer or debug.acpi.level prefixed
   with !.

 - Fully implement support for avoiding nodes in the ACPI namespace.
   Nodes may be listed in the debug.acpi.avoid environment variable;
   these nodes and all their children will be ignored (although still
   scanned over) by ACPI functions which scan the namespace.  Multiple
   nodes can be specified, separated by whitespace.

 - Implement support for selectively disabling ACPI subsystem components
   via the debug.acpi.disable environment variable.  The following
   components can be disabled:
    o bus	creation/scanning of the ACPI 'bus'
    o children	attachment of children to the ACPI 'bus'
    o button	the acpi_button control-method button driver
    o ec	the acpi_ec embedded-controller driver
    o isa	acpi replacement of PnP BIOS for ISA device discovery
    o lid	the control-method lid switch driver
    o pci	pci root-bus discovery
    o processor CPU power/speed management
    o thermal	system temperature detection and control
    o timer	ACPI timecounter
   Multiple components may be disabled by specifying their name(s)
   separated by whitespace.

 - Add support for ioctl registration.  ACPI subsystem components may
   register ioctl handlers with the /dev/acpi generic ioctl handler,
   allowing us to avoid the need for a multitude of /dev/acpi* control
   devices, etc.

15e32d5d03 Initial FreeBSD OSPM (operating system power management) modules for
ACPICA.  Most of these are still works in progress.  Support exists for:

 - Fixed feature and control method power, lid and sleep buttons.
 - Detection of ISA PnP devices using ACPI namespace.
 - Detection of PCI root busses using ACPI namespace.
 - CPU throttling and sleep states (incomplete)
 - Thermal monitoring and cooling control (incomplete)
 - Interface to platform embedded controllers (mostly complete)
 - ACPI timer (incomplete)
 - Simple userland control of sleep states.
 - Shutdown and poweroff.
