Tim Murray fb896944b6 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.

Mark Salyzyn 66ce3e08c5 system/core Replace cutils/log.h with android/log.h 
Should use android/log.h instead of cutils/log.h as a good example
to all others.  Adjust header order to comply with Android Coding
standards.

Ruchi Kandoi d3027d85f3 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.

Jeff Brown 0446e16f53 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.
