Fix the experimental NFS client so that it does not bogusly

set the f_flags field of "struct statfs". This had the interesting
effect of making the NFSv4 mounts "disappear" after r221014,
since NFSMNT_NFSV4 and MNT_IGNORE became the same bit.
Move the files used for a diskless NFS root from sys/nfsclient
to sys/nfs in preparation for them to be used by both NFS
clients. Also, move the declaration of the three global data
structures from sys/nfsclient/nfs_vfsops.c to sys/nfs/nfs_diskless.c
so that they are defined when either client uses them.

- * Structure that must be initialized for a diskless nfs client.

- * and to do a partial ifconfig(8) and route(8) so that the critical net
- * interface can communicate with the server.
- * The primary bootstrap is expected to fill in the appropriate fields before
- * starting the kernel.
- * Currently only works for AF_INET protocols.
- * NB: All fields are stored in net byte order to avoid hassles with
- * client/server byte ordering differences.

- * structure would not be prudent at this time, since almost all servers are
