VFS: Add an intent for LOOKUP_MOUNT
This will allow automounters etc to signal to a filesystem that the lookup is
intended for a 'mount' request, and that we shouldn't trigger any automounter
traps/upcalls.

usermodehelper: allow callers to set up the file descriptor table
When the NFS client starts an automounter process, it wants to be able to notifiy it
on which directory it needs to mount the new directory. We will do this by installing a
file descriptor to the directory, and then allowing the automounter to access it via
/proc/self/fd/<fd>.
We do this by generalising the existing subprocess_info->stdin mechanism to take
an arbitrary length array of files.

NFS: Make rpc_ops->access return attributes to the caller
Now that both NFSv3 and NFSv4 return attributes as part of the ACCESS call, we can
move the common code into nfs_do_access().
