To allow greater flexibility to where statd's state is kept,
statd's state path can now be decoupled from the normal
NFS state directory.

In configure.ac, the NSM_DEFAULT_STATEDIR definition will now define
the path to where the state information is kept.  The default
value, /var/lib/nfs, can be redefined with the --with-statdpath
flag.
