* lisp/filenotify.el (file-notify--rm-descriptor): Remove WHAT arg.
(file-notify-callback): Improve check for `stopped' event.  Call
`file-notify-rm-watch' rather than `file-notify--rm-descriptor'.
(file-notify-add-watch): In case FILE is not a directory, call the
file monitor for the kqueue backend.  Otherwise, call the
directory monitor for the upper directory.

* src/inotify.c (inotifyevent_to_event): Extract file name from
watch_object if the event doesn't provide it.
(Finotify_add_watch): Add file name to watch_object.

* test/automated/file-notify-tests.el (file-notify--test-timeout):
Use different timeouts for different libraries.
(file-notify--test-with-events): Suppress lock files.  Flush
outstanding events before running the body.
(file-notify-test02-events, file-notify-test04-file-validity): Do
not skip cygwin tests.  Add additional test for file creation.
Adapt expected result for different backends.
(file-notify-test03-autorevert): Some of the tests don't work for
w32notify.
(file-notify-test06-many-events): Rename into both directions.

* lisp/filenotify.el (file-notify-add-watch): Call the native
add-watch function on the file, not on the dir.

* src/kqueue.c (kqueue_compare_dir_list): Make also bookkeeping
about already deleted entries.

* test/automated/auto-revert-tests.el
(auto-revert-test01-auto-revert-several-files): Do not call "cp -f"
since this deletes the target file first.

* test/automated/file-notify-tests.el (file-notify--test-event-test):
Make stronger checks.
(file-notify-test01-add-watch, file-notify-test02-events)
(file-notify-test04-file-validity, file-notify-test05-dir-validity):
Rewrite in order to call file monitors but directory monitors.
(file-notify-test06-many-events): Ler rename work in both directions.

* src/kqueue.c (pending_events): Remove global variable.
(kqueue_compare_dir_list): Create `write' event for not used
pending events.
(globals_of_kqueue): Remove initialization of pending_events.

* src/kqueue.c (pending_events): New variable.
(kqueue_compare_dir_list): Handle more complex rename operation.
(globals_of_kqueue): Initialize pending_events.

* test/automated/file-notify-tests.el (file-notify-test06-many-events):
Adapt expected events in the `rename-file' case.
(file-notify-test06-many-events-remote): Declare.

* lisp/filenotify.el (file-notify-callback): Raise also event if
directory name matches.
(file-notify-add-watch): Add `create' to the flags for `kqueue'.

* src/kqueue.c (kqueue_generate_event): Use watch_object as
argument instead of ident.  Remove callback argument.  Adapt
callees.  Check actions whether they are monitored flags.

* test/automated/file-notify-tests.el (file-notify--test-library):
New defun.
(file-notify-test00-availability, file-notify-test02-events)
(file-notify-test04-file-validity)
(file-notify-test05-dir-validity): Use it.
(file-notify-test02-events, file-notify-test04-file-validity): Add
`read-event' calls between different file actions, in order to
give the backends a chance to rais an event.  Needed especially
for kqueue.  In case of deleting a directory, there are two
`deleted' events.

* src/kqueue.c (kqueue_directory_listing): Skip "." and "..".
(kqueue_compare_dir_list): Do not loop when calling
directory_files_internal.  Remove checks for "." and "..", this is
done in kqueue_directory_listing now.
(Fkqueue_add_watch): Check for proper emacs_open flags.

* src/kqueue.c (kqueue_directory_listing, kqueue_callback):
Simplify access to list.
(kqueue_compare_dir_list): Simplify access to list.  Raise
`delete' event if directory does not exist any longer.  Otherwise,
wait until directory contents has changed.  Fix error in check.

* lisp/filenotify.el (file-notify-callback): Handle also the
`rename' event from kqueue.

(kqueue_callback): Use them.  Call kevent() with a zero timeout.
(Fkqueue_add_watch): Adapt docstring.  Support directory events.
Compute initial directory listing.  Close file descriptor in case
of errors.
(syms_of_kqueue): Declare Qcreate.

* src/kqueue.c (Fkqueue_add_watch): O_BINARY is not a POSIX open(3)
flag.

* configure.ac (HAVE_KQUEUE): There is no pkg-config module for native
