This is hopefully the finally final tweak to the lightbar behavior. It does
this:
* When booting or awakening from sleep, Google colors pulse briefly.
* When the chromebook is fully on, lightbar is dim blue. Every 3-5 seconds,
a pulse of brighter blue sweeps across.
* On battery, the lightbar is not quite as bright, and the sweep goes in the
other direction and is slightly slower. If the battery charge drops below
10%, the lightbar changes from blue to red (but only on battery, not AC).
* When going to sleep (close lid while logged in), lightbar fades to black,
then pulses Google colors, then off.
* While asleep, lightbar does nothing, UNLESS on battery and battery charge
is under 10%. Then it pulses red every 5-8 seconds.
* When shutting off, it just goes black with no special effects.
Other than the slight dimming on battery power, there is no ambient light or
dynamic brightness control.

The remote temperature sensors for case temps are now not used until
they're calibrated by the host. But the EC still tries to control the
fan based on case temps. At best this has no effect because the
sensors haven't been enabled by host calibration. At worst, the host
calibrates them, but doesn't set up the temerature thresholds to
match, so the EC spins up the fan briefly during boot before the host
takes over (annoying), or potentially asserts prochot, shuts the
system down, or triggers a bunch of SMIs (really annoying). It's
safer just to leave these thresholds disabled by default; if the host
wants the EC to use them, it can easily set them at the same time it
sets the remote sensor calibration data.
Also, adjust overheated thresholds up based on snanda's recommendations.

2) discharge battery below 2%; when system shuts down it should also hibernate.
(I've also tested this with a hacked smart_battery.c which lies about
the battery state of charge, since that's faster than waiting for my
battery to discharge.)

This brings Randall's key debounce logic into STM32. We need to
rationalize the code, but for this morning...
This should fix problems with double keypresses and missing keypresses.

(some may be missing if you sweep too fast. there is a point where if
two keys are hit within 1.7ms of each other they can be swapped, but any
slower than that and they should never be out of order)

Experimentally it is possible to press a key on snow for only 4.8ms.
We should aim to scan more frequently to catch those who only just
touch the keys, or type very quickly.
It takes a little over 2ms to complete a keyboard scan at present.
We shold aim to reduce this, but for now, it seems safe to reduce the
default scanning frequency to 3ms.

At present the keyboard scan parameters are hard-coded, so changing them
requires a new EC image. This can be problematic if we want to adjust
the behavior of keyboard scanning since we must send an EC update.
Change stm32's keyboard scan to use run-time config. All parameters
and behavior should remain the same with this change.
The configuration is defined by ec_commands.h since we intend to create
a command to allow access to it. It does not seem worth defining a
separate structure within keyboard_scan at present, although if we
add a new version of the command in the future then we may want to
separate these.

Previously, an edge on a keyboard row could be missed if it occurred
after the last scan, but before interrupts are enabled. Now we
explicitly check if any keys are down before waiting for an interrupt,
and if any are, we simply don't wait to scan.

TEST=the race condition's really tricky to hit
The best we can do for testing is to ensure that we ARE sleeping in
the normal case where no keys are held down. For that, don't press
any keys, and run 'taskinfo' from the EC console twice about 10 sec
apart. Both printouts should have virtually identical times for the
KEYSCAN task.

Tell the host the battery is no longer charging when it hits 97%, and
set the power adapter LED to green.
This solves several problems:
1) The last 3% of charge takes a looong time. Kernel/ACPI/UI already
have a hack to show the battery as charged when it's about 3% from
full, but the EC still showed a yellow LED.
2) If the system is charged and you briefly unplug the adapter, the
LED turned yellow for a long time as it slowly trickle-charged. Now
it goes right to green.
3) A fully-charged battery will drop below 100% charge as it settles,
but won't accept more current at that time. This caused the LED to
turn yellow and stay there until the battery finally settled down to
~96%, at which point it'd accept more current and top itself off. The
whole time it did this, the kernel/ACPI/UI hack from (1) would keep
reporting "battery full". Now the LED stays green too.

- Discharge system to <95% full.
- Plug adapter in. LED should come on yellow.
- At around 97% full, the LED should turn green.
- Around that the UI will display "battery full".
(Note that due to rounding, the UI may take a few minutes to display
"battery full" after the LED goes green; that's ok)
- Unplug and replug adapter. LED should come on green. UI still reports
"battery full".
