* Fallback to polling for files not supported by kqueue

* Do not send an ENDEXISTS event on NOTE_REVOKE
* Handle kevent aggregation if multiple event types are requested
* Mimic FAM's behavior of never following symbolic links
* Add exhaustive error handling
* Remove all the legacy thread-safe code since gamin is now single-threaded

 FAM (File Alteration Monitor) system. This is a service provided by a library
 which allows to detect when a file or a directory has been modified.
 
+Whereas the FreeBSD port of FAM polls files every few seconds, this port
+includes a kqueue(2) backend for immediate notification of most alterations.
