This patch do following things:
1. When unmounting, we should try /proc/mounts first. Only then in
/etc/mtab if it wasn't found.
2. Reject name passed to us which is not starts with a '/' or not
contains a ':'
3. Fix the method to get UMNT protocol

This fix umount.nfs4's BUG, patch cleanup some useless code.
1. Combine nfs3_umount() and nfs2_umount() to nfs_umount()
2. If it is a nfs4 remote file system or unkown mount version, do not
probe remote mount port and not send UMNT request wich is not necessary

This patch lets umount to use correct UMNT version to do umount.
In latest kernel, the version format is "vers=3" etc., and in old kernel
the version format is "v3","v4" etc.

This patch is now hard-coded in the Makefile.am and cannot
be changed by configure. But as it needs to match what
util-linux does, that is probably a good thing.

If statd is not running (/var/run/rpc.statd.pid) when an nfs filesystem
is mounted (v2 or v3, with remote locking enabled), and if
/usr/sbin/start-statd (or other program specified at config time) is
present, then run that program to start statd.
This means that statd does not need to be running "just in case".
It only needs to be started at boot time if the nfs server is
started.

Solaris servers, when asked to share a filesystem with an anon-uid, will
report the only available authentication style as AUTH_NONE in the
reply from mountd (even though they actually accept AUTH_SYS and simply
ignore the credentiuals).
So if no sec= is specified we should really accept anything that can easily
be handled. ie. AUTH_SYS or AUTH_NONE.

which require it (pre-2.1.32/nfs_mount_version 1).

When connecting to an NFSv4 server we need to find out IP address
as it would be seen by the server, to register an address for
callbacks.
This is most easily done by connecting the socket to the
servers address and then getting the address of our endpoint.
However with a connected UDP socket, replies that come from a
different IP address - as can happen with non-Linux multi-homed
servers - will be rejected.
So if we connected our UDP socket, we need to be sure to
disconnect it before using it.
This patch adds an option to get_socket to say if we want it
connected or not and, in the case where we do, we disconnect
a UDP socket after the connection information has been used.
Also clean up the error handling in clnt_ping which was getting
clumsy.

Hi all,
I noticed some mtab corruption the other day when doing some autofs
testing but thought nothing of it.
When investigating another issue I came across utils/mount.c:add_mtab
which looks like it adds an entry to /etc/mtab without performing
correct locking. Perhaps this is not needed when adding entries but I
think it is.

We need to give an IP address to identify this client to the
server.
The current code does a gethostbyname of the hostname. One
some systems this returns 127.0.0.1 or similar, which is not useful.
Instead, use getsockname of the sock used to connect to the server
to confirm that the server is working. This gives the address on the
interface that was chosen to talk to that server, which is the
best address we can find (if there is a NAT in the way, it might
still not work, but in that case there is nothing we can do).
