libsuspend: move to exponential backoff
If for some reason the system can't suspend (usually a driver bug),
libsuspend will currently attempt to retry suspend after 100ms. Because
entering suspend takes a significant amount of CPU time, this can be
extremely expensive and be a major contributor to rapid battery
drain. Move autosuspend to use exponential backoff if the previous
suspend attempt failed.

Adds a parameter to the wakeup_callback to report sucessful wakeup or suspend aborts.
Adds the call to wakeup_callback when the write to the /sys/power/state
fails. This will help userspace account for the suspend aborts.

Add TEMP_FAILURE_RETRY to libsuspend.
In testing, I observed one instance of a call failing due to a signal
sent to the process. This could happen at various times so it's better
to be safe than sorry.

libsuspend provides functions autosuspend_enable() and
autosuspend_disable() to trigger suspend on a variety of different
kernels.
