Title: Check for comments and empty lines in ipsetbuild input files

1. Check for comments in input files. Valid comments start with '#' in column
one. In-line comments are not allowed and not checked.

2. Check if a line is whitespace (\n, \t, \r, ' ').

If either condition is true, the line is skipped.
