pm-graph v5.9

bootgraph:
 - fix parsing of /proc/version to be much more flexible
 - check kernel version to disallow ftrace on anything older than 4.10

sleepgraph:
 - include fix to bugzilla 212761 in case it regresses
 - fix for -proc bug: intel/pm-graph#20
 - add -debugtiming arg to get timestamps on prints
 - allow use of the netfix tool hosted in the github repo
 - read s0ix data from pmc_core for better debug
 - include more system data in the output log
 - Do a better job testing input files useability
 - flag more error data from dmesg in the timeline
 - pre-parse the trace log to fix any ordering issues
 - add new parser to process dmesg only timelines
 - remove superflous sleep(5) in multitest mode

config/custom-timeline-functions.cfg:
 - change some names to keep up to date

README:
 - new version, small wording changes
