Ingo Weinhold 97aabbede9 Add BLowLevelPackageContentHandler section hooks
* Add hooks HandleSectionStart() and HandleSectionEnd(). They are
  invoked to bracket package file section, so the handler can
  discriminate which section the attributes belong to.
  HandleSectionStart() features a return parameter _handleSection, which
  allows to handler to pick which sections it wants to handle.
* "package dump" does now print the section names.
