* commit 'origin/2287_persistent_bookmarks':
  Fix in lib/logging.c for proper work on 64-bit platforms.
  Change of bookmark drawing.
  Fixed memory leak: destroy serialization bookmarks if file position is not saved.
  Use GArray for bookmarks instead of raw array.
  Minor optimization, type accuracy, includes fix.
  Ticket #2287 (mcedit: persistent bookmarks)
