Moved from scripts into tools, and updated from 4.5 to 4.6
- Changed the tool title to SleepGraph
- Reformatted the code so analyze_suspend can be used as a library
- Reorganized all html/js/css handling code to be used by other tools
- upgraded the -summary feature to work faster with better readability

Cc: arjan, len.brown, todd.e.brandt, todd.e.brandt
First release into the kernel tools source
- pulls in analyze_suspend.py as as library, same html formatting
- supplants scripts/bootgraph.pl, outputs HTML instead of SVG
- enables automatic reboot and collection for easy timeline capture
- enables ftrace callgraph collection from early boot
