Subject: [PATCH 1/4] power: Enable power-saver profile when low on battery
When low on battery, and if the feature is enabled, hold the power
profile to "power-saver" until the battery is sufficiently recharged.

Subject: [PATCH 2/4] power: Dim screen faster if power saver mode is on
As done on other platforms, aggressively dim the screen after a
short period when the user has selected to enter power saver mode.
The same aggressive screen dim will be used if the battery is low and
power-profiles-daemon is not available. If it is available, then it
fixes a screen dim happening when the battery was low which might
have been unwanted.

Subject: [PATCH 4/4] power: When dimming the screen, dim it quicker by default
Now that we respect the "dim when idle" setting[1], dim quicker to try
and save more power. 4/5 of the timeout to the screensaver was always a
bit too undecided as a fraction, even when using the dimming as a
warning that the screen was going to go to the screensaver (see commit
7bc750a5).
