from 2.4.3 to 2.4.4
- fixed man pages in the NAME section: added whatis entry
- fixed segfault: in the internal error reporting code (delete[] in place of
  free())
- fixed bug: dar_manager was not able to read properly the latest generated
  databases version when having Extended Attributes recorded for some files
- avoided reporting unreleased memory block when compilation optimization
  have been used (dar, dar_manager, dar_cp, dar_slave, dar_xform do all
  reported unreleased memory when gcc optimization was used in "infinint" mode)
