ncpfs: move net/ncpfs to drivers/staging/ncpfs

The Netware Core Protocol is a file system that talks to
Netware clients over IPX. Since IPX has been dead for many years
move the file system into staging for eventual interment.

-# NCP Filesystem configuration
-#
-config NCP_FS
-	tristate "NCP file system support (to mount NetWare volumes)"
-	depends on IPX!=n || INET
-	help
-	  NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
-	  used by Novell NetWare clients to talk to file servers.  It is to
-	  IPX what NFS is to TCP/IP, if that helps.  Saying Y here allows you
-	  to mount NetWare file server volumes and to access them just like
-	  any other Unix directory.  For details, please read the file
-	  <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
-	  the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
-
-	  You do not have to say Y here if you want your Linux box to act as a
-	  file *server* for Novell NetWare clients.
-
-	  General information about how to connect Linux, Windows machines and
-	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
-
-	  To compile this as a module, choose M here: the module will be called
-	  ncpfs.  Say N unless you are connected to a Novell network.
-
-config NCPFS_PACKET_SIGNING
-	bool "Packet signatures"
-	depends on NCP_FS
-	help
-	  NCP allows packets to be signed for stronger security. If you want
-	  security, say Y.  Normal users can leave it off.  To be able to use
-	  packet signing you must use ncpfs > 2.0.12.
-
-config NCPFS_IOCTL_LOCKING
-	bool "Proprietary file locking"
-	depends on NCP_FS
-	help
-	  Allows locking of records on remote volumes.  Say N unless you have
-	  special applications which are able to utilize this locking scheme.
-
-config NCPFS_STRONG
-	bool "Clear remove/delete inhibit when needed"
-	depends on NCP_FS
-	help
-	  Allows manipulation of files flagged as Delete or Rename Inhibit.
-	  To use this feature you must mount volumes with the ncpmount
-	  parameter "-s" (ncpfs-2.0.12 and newer).  Say Y unless you are not
-	  mounting volumes with -f 444.
-
-config NCPFS_NFS_NS
-	bool "Use NFS namespace if available"
-	depends on NCP_FS
-	help
-	  Allows you to utilize NFS namespace on NetWare servers.  It brings
-	  you case sensitive filenames.  Say Y.  You can disable it at
-	  mount-time with the `-N nfs' parameter of ncpmount.
-
-config NCPFS_OS2_NS
-	bool "Use LONG (OS/2) namespace if available"
-	depends on NCP_FS
-	help
-	  Allows you to utilize OS2/LONG namespace on NetWare servers.
-	  Filenames in this namespace are limited to 255 characters, they are
-	  case insensitive, and case in names is preserved.  Say Y.  You can
-	  disable it at mount time with the -N os2 parameter of ncpmount.
-
-config NCPFS_SMALLDOS
-	bool "Lowercase DOS filenames"
-	depends on NCP_FS
-	---help---
-	  If you say Y here, every filename on a NetWare server volume using
-	  the OS2/LONG namespace and created under DOS or on a volume using
-	  DOS namespace will be converted to lowercase characters.
-	  Saying N here will give you these filenames in uppercase.
-
-	  This is only a cosmetic option since the OS2/LONG namespace is case
-	  insensitive. The only major reason for this option is backward
-	  compatibility when moving from DOS to OS2/LONG namespace support.
-	  Long filenames (created by Win95) will not be affected.
-
-	  This option does not solve the problem that filenames appear
-	  differently under Linux and under Windows, since Windows does an
-	  additional conversions on the client side. You can achieve similar
-	  effects by saying Y to "Allow using of Native Language Support"
-	  below.
-
-config NCPFS_NLS
-	bool "Use Native Language Support"
-	depends on NCP_FS
-	select NLS
-	help
-	  Allows you to use codepages and I/O charsets for file name
-	  translation between the server file system and input/output. This
-	  may be useful, if you want to access the server with other operating
-	  systems, e.g. Windows 95. See also NLS for more Information.
-
-	  To select codepages and I/O charsets use ncpfs-2.2.0.13 or newer.
-
-config NCPFS_EXTRAS
-	bool "Enable symbolic links and execute flags"
-	depends on NCP_FS
-	help
-	  This enables the use of symbolic links and an execute permission
-	  bit on NCPFS. The file server need not have long name space or NFS
-	  name space loaded for these to work.
-
-	  To use the new attributes, it is recommended to use the flags
-	  '-f 600 -d 755' on the ncpmount command line.
