intelli_plug: refactor stats calculation code to be less intrusive

this is done for those kernels which do not have 100% source code available
and must use existing closed source modules such as wifi drivers

kernel/power/powersuspend: cumulative update to version 1.5

- fix hybrid-kernel mode cannot be set through sysfs

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend v1.4 (Yank555.lu)

- add hybrid-kernel mode (autosleep and panel, first wins)
- default to hybrid-kernel mode
- harmonize debug message with my other stuff
- include all 3 modes as default, so it's only commenting out to change

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend v1.3 (Yank555.lu)

- fix stupid typo
- add an alternative hook for screen on / off detection in the display panel driver
(sleeps ~0.1s sooner, wakes up ~1s later then autosleep)

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend v1.2 (Yank555.lu)

- make kernel / userspace mode switchable

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend v1.1 (Yank555.lu)

- make powersuspend not depend on a userspace initiator anymore, but use a hook in autosleep instead.

kernel/power/powersuspend: new PM kernel driver for Android w/o early_suspend (faux123)

Android early_suspend/late_resume PM kernel driver framework has been
deprecated by Google. This new powersuspend PM kernel driver is a replacement
for it and existing early_suspend drivers can be easily adapted to use this
new replacement driver
