The file handle affinity code was configured to be used by both the old and new NFS servers. This no longer makes sense, since there is only one NFS server. This patch copies a majority of the code in sys/nfs/nfs_fha.c and sys/nfs/nfs_fha.h into sys/fs/nfsserver/nfs_fha_new.c and sys/fs/nfsserver/nfs_fha_new.h, so that the files in sys/nfs can be deleted. The code is simplified by deleting the function callback pointers used to call functions in either the old or new NFS server and they were replaced by calls to the functions. As well as a cleanup, this re-organization simplifies the changes required for handling of external page mbufs, which is required for KERN_TLS. This patch should not result in a semantic change to file handle affinity.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
