samba: remove Linux cifs-utils files from samba master branch

This patch removes all of the files from the samba tree that should now
be provided by the cifs-utils package. It also drops a
"README.cifs-utils" into the topdir with a URL to the main cifs-utils
webpage. This is for people who don't want the lists and might be taken
by surprise by the change. That's optional, but I think it's a good idea
for a least a release or two.

-<para>cifs.upcall is a userspace helper program for the linux CIFS client
-filesystem. There are a number of activities that the kernel cannot easily
-do itself. This program is a callout program that does these things for the
-kernel and then returns the result.</para>
-
-<para>cifs.upcall is generally intended to be run when the kernel calls
-request-key<manvolnum>8</manvolnum> for a particular key type. While it
-can be run directly from the command-line, it's not generally intended
-to be run that way.</para>

-		<para>This is less secure than not trusting DNS. When using this option, it's possible that an attacker could get control of DNS and trick the client into mounting a different server altogether. It's preferable to instead add server principals to the KDC for every possible hostname, but this option exists for cases where that isn't possible. The default is to not trust reverse hostname lookups in this fashion.

-	<para>mount.cifs mounts a Linux CIFS filesystem. It
-is usually invoked indirectly by
-the <citerefentry><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry> command when using the 
-"-t cifs" option. This command only works in Linux, and the kernel must
-support the cifs filesystem. The CIFS protocol is the successor to the 
-SMB protocol and is supported by most Windows servers and many other
-commercial servers and Network Attached Storage appliances as well as 
-by the popular Open Source server Samba.
-	</para>
-
-	<para>
-	The mount.cifs utility attaches the UNC name (exported network resource)
-	specified as <emphasis>service</emphasis> (using //server/share syntax,
-	where "server" is the server name or IP address and "share" is the name
-	of the share) to the local directory <emphasis>mount-point</emphasis>.
-	</para>
-
-	<para>
-		Options to <emphasis>mount.cifs</emphasis> are specified as a comma-separated
-list of key=value pairs. It is possible to send options other
-than those listed here, assuming that the cifs filesystem kernel module (cifs.ko) supports them.   
-Unrecognized cifs mount options passed to the cifs vfs kernel code will be logged to the
-kernel log.
-
-	</para>
-
-	<para><emphasis>mount.cifs</emphasis> causes the cifs vfs to launch a thread named cifsd. After mounting it keeps running until
-		the mounted resource is unmounted (usually via the umount utility).

-	<title>SERVICE FORMATTING AND DELIMITERS</title>
-
-	<para>
-		It's generally preferred to use forward slashes (/) as a delimiter in service names. They are considered to be the "universal delimiter" since they are generally not allowed to be embedded within path components on Windows machines and the client can convert them to blackslashes (\) unconditionally. Conversely, backslash characters are allowed by POSIX to be part of a path component, and can't be automatically converted in the same way.
-	</para>
-	<para>
-		mount.cifs will attempt to convert backslashes to forward slashes where it's able to do so, but it cannot do so in any path component following the sharename.

-	<title>INODE NUMBERS</title>
-	<para>
-		When Unix Extensions are enabled, we use the actual inode
-	number provided by the server in response to the POSIX calls as an
-	inode number.
-	</para>
-	<para>
-		When Unix Extensions are disabled and "serverino" mount option
-	is enabled there is no way to get the server inode number. The
-	client typically maps the server-assigned "UniqueID" onto an inode
-	number.
-	</para>
-	<para>
-		Note that the UniqueID is a different value from the server
-	inode number. The UniqueID value is unique over the scope of the entire
-	server and is often greater than 2 power 32. This value often makes
-	programs that are not compiled with LFS (Large File Support), to
-	trigger a glibc EOVERFLOW error as this won't fit in the target
-	structure field. It is strongly recommended to compile your programs
-	with LFS support (i.e. with -D_FILE_OFFSET_BITS=64) to prevent this
-	problem. You can also use "noserverino" mount option to generate inode
-	numbers smaller than 2 power 32 on the client. But you may not be able
-	to detect hardlinks properly.

-	<title>FILE AND DIRECTORY OWNERSHIP AND PERMISSIONS</title>
-
-	<para> The core CIFS protocol does not provide unix ownership
-information or mode for files and directories. Because of this, files
-and directories will generally appear to be owned by whatever values the
-uid= or gid= options are set, and will have permissions set to the
-default file_mode and dir_mode for the mount. Attempting to change these
-values via chmod/chown will return success but have no effect.</para>
-
-	<para>When the client and server negotiate unix extensions,
-files and directories will be assigned the uid, gid, and mode provided
-by the server. Because CIFS mounts are generally single-user, and the
-same credentials are used no matter what user accesses the mount, newly
-created files and directories will generally be given ownership
-corresponding to whatever credentials were used to mount the
-share.</para>
-
-	<para>If the uid's and gid's being used do not match on the
-client and server, the forceuid and forcegid options may be helpful.
-Note however, that there is no corresponding option to override the
-mode. Permissions assigned to a file when forceuid or forcegid are in
-effect may not reflect the the real permissions.</para>
-
-	<para>When unix extensions are not negotiated, it's also
-possible to emulate them locally on the server using the "dynperm" mount
-option. When this mount option is in effect, newly created files and
-directories will receive what appear to be proper permissions. These
-permissions are not stored on the server however and can disappear at
-any time in the future (subject to the whims of the kernel flushing out
-the inode cache). In general, this mount option is discouraged.
-	</para>
-
-	<para>It's also possible to override permission checking on the client
-altogether via the noperm option. Server-side permission checks cannot be
-overriden. The permission checks done by the server will always correspond to
-the credentials used to mount the share, and not necessarily to the user who is accessing the share.</para>

-<citerefentry><refentrytitle>umount</refentrytitle><manvolnum>8</manvolnum></citerefentry> command 
-when umount.cifs is in /sbin directory, unless you specify the "-i" option to umount.  Specifying -i to umount avoids execution of umount helpers such as umount.cifs. The umount.cifs command only works in Linux, and the kernel must
-support the cifs filesystem. The CIFS protocol is the successor to the

-It is possible to set the mode for umount.cifs to
