Alan Somers 32fbc5d824 nfs: don't truncate directory cookies to 32-bits in the NFS server
In NFSv2, the directory cookie was 32-bits.  NFSv3 widened it to
64-bits and SVN r22521 widened the corresponding argument in
VOP_READDIR, but FreeBSD's NFS server continued to treat the cookies as
32-bits, and 0-extended to fill the field on the wire.  Nobody ever
noticed, because every in-tree file system generates cookies that fit
comfortably within 32-bits.

Also, have better type safety for txdr_hyper.  Turn it into an inline
function that type-checks its arguments.  Prevents warnings about
shift-count-overflow.
