AcpiOsSleepUsec() -> AcpiOsStall()

Improve some error messages slightly.

Use msleep() when we sleep waiting for a GPE, since we are holding the
ACPI mutex.

Add some comments to EcWaitEventIntr.

Clean up deviant style, add debugging to be consistent.

- 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)

AcpiOsSleep.
- Add AcpiOsGetThreadId.
- Simplify mutex code (still disabled).

Axe an unused static softc.

Change Embedded Controller lock to ACPI Global Lock.This is needed for
mutual execution between BIOS and OS.

Change priority of procedure queueing.
This is needed to next ACPICA import.

Fix with debugging option.

- 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.
