Improve how the parser is generated

- use long variant of options for re2c in its makefile
- use `define` instead of magic numbers
- add some consts
- trailing `;` are now mandatory for conditions
- NULL bytes are no longer allowed in configuration file
- the parser shouldn't crash in the absence of trailing new line at the end of its configuration file
