(auto-revert-notify-handler): Handle also gfilenotify.

* lisp/subr.el: (file-notify-handle-event): New defun. Replacing ...
(inotify-event-p, inotify-handle-event, w32notify-handle-event):
Removed.

* src/Makefile.in (NOTIFY_OBJ): New variable.
(base_obj): Replace inotify.o by $(NOTIFY_OBJ).

Call syms_of_gfilenotify.

* src/gfilenotify.c: New file.

* src/keyboard.c (Qfile_notify): New variable.  Replaces Qfile_inotify
and Qfile_w32notify.
(top): Wrap respective code by HAVE_GFILENOTIFY, HAVE_INOTIFY,
HAVE_W32NOTIFY and USE_FILE_NOTIFY.

* src/lisp.h: Declare syms_of_gfilenotify.

* src/termhooks.h (e): Wrap enum by USE_FILE_NOTIFY.

This arranges for filesystem events pertaining to FILE to be reported
to Emacs. Use `gfile-rm-watch' to cancel the watch.
Value is a descriptor for the added watch. If the file cannot be
watched for some reason, this function signals a `file-error' error.
FLAGS is a list of conditions to set what will be watched for. It can
include the following symbols:
'watch-mounts' -- watch for mount events
'send-moved' -- pair 'deleted' and 'created' events caused by file
renames (moves) and send a single 'event-moved'
event instead
When any event happens, Emacs will call the CALLBACK function passing
it a single argument EVENT, which is of the form
(DESCRIPTOR ACTION FILE [FILE1])
DESCRIPTOR is the same object as the one returned by this function.
ACTION is the description of the event. It could be any one of the
following:
'changed' -- FILE has changed
'changes-done-hint' -- a hint that this was probably the last change
in a set of changes
'deleted' -- FILE was deleted
'created' -- FILE was created
'attribute-changed' -- a FILE attribute was changed
'pre-unmount' -- the FILE location will soon be unmounted
'unmounted' -- the FILE location was unmounted
'moved' -- FILE was moved to FILE1
FILE is the name of the file whose event is being reported. FILE1
will be reported only in case of the 'moved' event. */)
