    general:
    - add battery charge data before and after test
    - remove special s0i3 handling
    - remove melding of dmesg & ftrace data in old kernels, use one only
    - updates to various kprobes in trace (ksys_sync, etc)
    - enable pm_debug_messages during the test
    - instrument more subsystems with dev functions (phy0)
    
    error handling:
    - return codes for tool show the status of the test run
    - 0: success, 1: general error (no timeline), 2: fail (suspend aborted)
    - monitor output of /sys/power/state, mark as failure if exception occurs
    - add signal handler when using -result to catch tool exceptions
    
    display control
    - add -x commands for testing xset with mode settings and status
    - allow display setting to on, off, suspend, standby
    - add display mode change info to the log, along with a warning on fail
    
    s2idle (freeze)
    - remove fixed 10-phase dependency, allow any phase order & any count
    - multiple phase occurences show as phase_nameN e.g. suspend_noirq3
    - if multiple freezes occur, print multiple time values in header
    
    summary:
    - add new columns to summary output: issues, worst suspend/resume devices
    - worst device: includes summation of all phases of suspend or resume
    - issues: includes WARNING/ERROR/BUG from dmesg log, and other issues
    - s2idle: multiple freezes show as FREEZExN in the issues column
