- changed output from single html file to dir with html/dmesg/ftrace
- add sysinfo to logs and timeline
- add -sysinfo command, displays dmidecode values and cpu/mem info
- set trace buffer size to lesser of memtotal/2 or 2GB when using callgraph
- extended timeline to the last init call in user space
separated timeline into two phases, kernel mode & user mode
- add kernel version check for ftrace usage, 4.10 minimum
- change -filter argument to -func
- add strict protections on -func usage with full symbol checks
now only works for statically linked functions
cmd -flistall now ignores all loadable module functions
- add -cgfilter argument for reducing timeline size by removing callgraphs
- crontab usage: preserve existing @reboot lines in user crontab
- fedora support added: uses grub2 loader, handles fedora crontab
- stop using "which" to find binaries, search pre-defined path list
- moved most output processing to analyze_suspend library

- 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
