edd84e4843 Checkpoint reworking the man page to be more useful to non-developers,
document some debug output variables, etc.  Mdoc assistance welcome.

276cd9216d Unify ACPI_DEBUG support for all OEM drivers under ACPI_OEM. Since more than
one will never be supported on the same platform, this does not hurt
debugging.

a2afe45a8a Rework acpi_cpu_idle() to select the next idle state before sleeping, not
after.  Unify the paths for all Cx states.  Remove cpu_idle_busy and
instead do the little profiling we need before re-enabling interrupts.
Use 1 quantum as estimate for C1 sleep duration since the timer interrupt
is the main reason we wake.

While here, change the cx_history sysctl to cx_usage and report statistics
for which idle states were used in terms of percent.  This seems more
intuitive than counters.  Remove the cx_stats structure since it's no
longer used.  Update the man page.

Change various types which do not need explicit size.

4e376d58dc Add a "quirks" value to disable quirks handling for a given boot.
Also, disable quirks if booting with a custom DSDT.  Add a quirk

blacklisted.

3184cf5a6b Add support for quirks for acpi tables. Key off OEM vendor and revision.
Sort acpi debug values.  Change "disable" to "disabled" to match rest of
the kernel.  Remove debugging from acpi_toshiba since it was only used for
probe/attach.

5413d9e096 Make the distinction between sysctl kernel environment variables and
device.hints kernel environment variables when disabling ACPI.

Some users are getting confused when they see hint.acpi.0.disabled.
They are confusing it with a sysctl MIB.

Finally, add a reference for device.hints(5) and kenv(1)
in the "SEE ALSO" section of the man page.

d3e1c2411e Fix hw.acpi.os_name by renaming it to hw.acpi.osname. The "_name" suffix
is reserved by the loader, and thus any tunable name with that suffix will
be silently discarded.

Document this in the header and man page so that other developers do not
develop so many bumps on the head after banging it against the wall.

c25a3f8a7a Improve the section on Cx states, documenting the removal of -1 as a
valid value for cx_lowest.  To disable sleeping, use machdep.cpu_idle_hlt
instead.  Update the version of the ACPI spec we implement.

6b74f9b7f5 Implement Cx CPU idle states and updated throttling support.
* Use the cpu_idle_hook() to do idling for C1-C3.
* Use both _CST and the FADT to detect Cx states.
* Use both _PTC and P_CNT for controlling throttling.
* Add a notify handler to detect changes in _CST and _PSS
* Call the _INI function for each processor if present.  This will be
  done by ACPI-CA in the future.
* Fix a bug on SMP systems where CPUs will attach multiple times if the
  bus is rescan.
* Document new sysctls for controlling idling.
