a197aac2f6 timeval_func: move all timeval manipulation to separate file
There are several definitions of the same functions manipulating timeval
structures. Let's move them to separate file and arrange the code
preperly.

648ad4db6f Linting change.
Remove config parser/lexer code as it's rebuilded every time but can
break adding new config options.
Also clean up the code base to avoid mixing actual code changes and lint
issues.
