Imported envsys 2, a brief description of the new features:
(Part 3: userland)

* Support for detachable sensors.
* Cleaned up the API for simplicity and efficiency.
* Ability to send capacity/critical/warning events to powerd(8).
* Adapted all the code to the new locking order.
* Compatibility with the old envsys API: the ENVSYS_GTREINFO
and ENVSYS_GTREDATA ioctl(2)s are supported.
* Added support for a 'dictionary based communication channel' between
sysmon_power(9) and powerd(8), that means there is no 32 bytes event
size restriction anymore.
* Binary compatibility with old envstat(8) and powerd(8) via COMPAT_40.
* All drivers with the n^2 gtredata bug were fixed, PR kern/36226.

Power management daemon for sysmon. Currently supports acting on
power switch state change events.

Fix spelling of "occurs".

Minor grammar fix, from Bug Hunting in PR 47159.

Merge single-letter options in SYNOPSIS.

Add an option to not actually run the power management scripts, and
when in debug mode send all error messages to stderr rather than to
syslog(8).

Bump date for previous.

Some miscellaneous fixes:

* Apparently there is only a single location for the scripts. Thus, remove
the references to "/etc/powerd/scripts/apm" and "/etc/powerd/scripts/acpi".
* Correct confusion: instead of "the device with which the device is
associated", write "the device with which the event is associated".
Correct also an example related to this.
* Improve wording, grammar, and markup in few places.

Emphasize the script names and events.

New sentence, new line.

branches: 1.18.12;
Note addition of hotkey_button scripts.

Document the 'low-power' event in the sensor_battery script.

Mention that I added support to handle envsys(4) events.

Improve grammar.

Update to match current kernel code.

branches: 1.13.4;
Explain that sensor_indicator will be used for indicators and integers.

sensor_indicator is able to receive the same events than other sensors.

Add the /etc/powerd/scripts/sensor_indicator to handle events on
indicator sensors.

Update powerd(8).

This only has one option so get rid of plural "s".

Add comma in enumeration; use Aq instead of \*[Lt]\*[Gt].

Describe AC adapter events.

Bump date for last; sort sections; comment out sysmon(4) xref for now.

Note that scripts are run synchronously.

Document the reset_button script.

New sentence, new line. Use \*[Lt],\*[Gt] for easier HTML conversion.

Remove an extra prop_object_release().

Duh! add missing free(3) in previous.

In debug mode, don't forget to free the buffer returned by
prop_dictionary_externalize().
