Add strace event handling for: creat, link, unlink, mkdir, rmdir, statfs.
Add strace event handling for: creat, link, unlink, mkdir, rmdir, statfs.

Enforce stricter checks for strace log parsing. In many handler, now check for
result.startswith('0') instead of not result.startswith('-1').

Improve error message on unknown trace line by standardizing the argument
parsing with parse_args function decorator.
