"struct nfs_args" as the regular NFS client. This is needed so that the old mount(2) syscall will work and it makes sharing of the diskless NFS root code easier. Eary in the porting exercise I introduced a new revision of nfs_args, but didn't actually need it, thanks to nmount(2). I re-introduced the NFSMNT_KERB flag, since it does essentially the same thing and the old one would not have been used because it never worked. I also added a few new NFSMNT_xxx flags to sys/nfsclient/nfs_args.h that are used by the experimental NFS client. MFC after: 2 weeks
