/**

 Watch directories and files for changes.
 The watched directories or files don't have to exist yet.
 When a watched directory is changed, i.e. when files therein are
 created or deleted, KDirWatch will emit the signal dirty().
 When a watched, but previously not existing directory gets created,
 KDirWatch will emit the signal created().
 When a watched directory gets deleted, KDirWatch will emit the
 signal deleted(). The directory is still watched for new
 creation.
 When a watched file is changed, i.e. attributes changed or written
 to, KDirWatch will emit the signal dirty().
 Scanning of particular directories or files can be stopped temporarily
 and restarted. The whole class can be stopped and restarted.
 Directories and files can be added/removed from the list in any state.
 The implementation uses the FAM service when available;
 if FAM is not available, the DNOTIFY functionality is used on LINUX.
 As a last resort, a regular polling for change of modification times
 is done; the polling interval is a global config option:
 DirWatch/PollInterval and DirWatch/NFSPollInterval for NFS mounted
 directories.
 See {@link KDirWatchSignals} for signals emitted by KDirWatch
