FUNCTION: FtpChangeNotify
Convert the relative pidls into absolute pidls, then hand onwards
to SHChangeNotify. If we can't do the notification, tough.
Issuing a change notify also invalidates the name-cache, because
we know that something happened to the directory.
If we wanted to be clever, we could edit the name-cache on the
fly, but that would entail allocating a new name-cache, initializing
it with the edited directory contents, then setting it as the new
cache. (We can't edit the name-cache in place because somebody
might still be holding a reference to it.) And all this work needs
to be done under the critical section, so that nobody else tries
to do the same thing simultaneously. What's more, the only thing
that this helps is the case where the user opens two views on
the same folder from within the same process, which not a very
common scenario. Summary: It's just not worth it.
Note that this must be done at the CFtpFolder level and not at the
CFtpDir level, because CFtpDir doesn't know where we are rooted.
(We might have several instances, each rooted at different places.)
_UNDOCUMENTED_: The pidl1 and pidl2 parameters to SHChangeNotify
are not documented. It is also not mentioned (although it becomes
obvious once you realize it) that the pidls passed to SHChangeNotify
must be absolute.

UNIX and Win32 semantics on file permissions are different.
On UNIX, the ability to rename or delete a file depends on
your permissions on the parent folder.

your permissions on the file itself.
