pm-graph: AnalyzeSuspend v4.7

- changed -rtcwake parameter to be on & 15 sec by default,
  to disable rtcwake use: "-rtcwake off"
- changed behavior of -o: renames HTML file on rerun, subdir on new run
- changed execution_misalignment error to missing_function_name
- add sysinfo to logs and timeline via a custom dmidecode call
  it supplants dmidecode tool when used as a library call
- add -sysinfo command, displays dmidecode values and cpu/mem info
- set trace buffer size to lesser of memtotal/2 or 2GB when using callgraph
- add support for /sys/power/mem_sleep. if mem_sleep found:
  mem-shallow=standby, mem-s2idle=freeze, mem-deep=mem
- remove redundant javascript
- cosmetic changes to HTML layout
