Refactor mount processing slightly to remove an output parameter and an
unnecessary type cast. The mount syscall is now made from inside
nfs_mount or nfs4mount, rather than in common code after those are called.
Code review suggests that EX_BG was never returned by mount.nfs because the
logic I just replaced was always returning EX_FAIL. The new logic should
properly return EX_BG when appropriate.
However, it is unclear whether /bin/mount handles backgrounding the mount
request, or whether mount.nfs should.

I'd like to be able to use the same pseudoflavor data in exportfs and
mountd; so move it to nfslib and a common include.

Prior to David Howell's mount changes in 2.6.18, users who mounted
different directories which happened to be from the same filesystem on the
server would get different super blocks, and hence could choose different
mount options. As long as there were no hard linked files that crossed from
one subtree to another, this was quite safe.
Post the changes, if the two directories are on the same filesystem (have
the same 'fsid'), they will share the same super block, and hence the same
mount options.
Add a flag to allow users to elect not to share the NFS super block with
another mount point, even if the fsids are the same. This will allow
users to set different mount options for the two different super blocks, as
was previously possible. It is still up to the user to ensure that there
are no cache coherency issues when doing this, however the default
behaviour will be to share super blocks whenever two paths result in
the same fsid.

While it is nice to have the checks, nothing in this package
creates the files that are checked, so we shouldn't check them
yet.

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).

Adds the mount directory and the code to mount and umount the NFS file system.
