* setup.c: save and restore new global variable/option

* ftpfs.c (ftp_use_unix_list_options): New global variable/option.
If true we try to use 'LIST -la <path>'. When it fails we use the
two commands 'CWD <path>' and 'LIST' instead.
(resolve_symlink): rewritten. Don't get a second directory listing
with `LIST -lLa'. Instead use the cache to get the file stat of
symbolic links. If the directory the symlink points to isn't
already in the cache the directory listing will be fetched and
stored in the directory cache (without resolving symlinks
recursively).
The new method to resolve symlinks is faster if symlinks
the same directory or the directory the symlink points to
is already in the cache.
This function was small and nice until I discovered that it was
broken for symlinks to symlinks. Now it looks ugly and perhaps I
will revert it to use "LIST -lLa" again. With a fast connection it
doesn't matter which methode we use but with a slow connection I
wouldn't hesitate to burn more cpu cycles on the client side.
(retrieve_dir): Added parameter to tell whether to resolve
symlinks (don't resolve symlinks in directory listings retrieved
while resolving symlinks).
When we don't get a directory listing with 'LIST -la <path>' then
try to get it with `CWD <path>; LIST'.

* ftpfs.c (login_server): s/ftpfs_get_host/my_get_host/
(retrieve_file_start2): Don't create target file O_EXCL, in
copy_file_file we check existance of the target file and know
that we want to truncate it (this change was already done a
while back but it was reverted with the vfs-split).

* ftpfs.h (struct connection): added boolean which indicates that
the ftp server doesn't unterstand Unix ls options
* ftpfs.h (struct dir): added enum to store symlink status of the
in memory directory cache (directory has no symbolic links;
symbolic links but not yet resolved; symbolic links which are resolved)
Tue Sep 15 20:02:08 1998 Norbert Warmuth <k3190@fh-sw.de>
* shared_ftp_fish.c, fish.c: updated references to retrieve_dir to
honour the additional boolean parameter
