- Bugfix: canlock-mhp utility no longer hangs if field name was not
  found
- Bugfix: Two memory leaks fixed in canlock-hfp utility
  (Reported by Dennis Preiser)
- Bugfix: Typo in canlock-mhp man page fixed
  (Reported by Julien Élie)
- Library libcanlock-hp added to execute the header parsers
  (for operating systems with POSIX API)
- New libcanlock-hp API function to unfold header fields added
  (Suggested by Julien Élie)
- Test suite extended for the new library. Tests for parser functions
  are skipped by default (because they require the installed parser
