Summary

Update references to the new sysctls:

kern.ipc.somaxconn       -> kern.ipc.soacceptqueue
vfs.zfs.arc_max          -> vfs.zfs.arc.max
vfs.zfs.arc_min          -> vfs.zfs.arc.min
vfs.zfs.min_auto_ashift  -> vfs.zfs.vdev.min_auto_ashift
vfs.zfs.prefetch_disable -> vfs.zfs.prefetch.disable
vfs.zfs.zil_disable      -> vfs.zfs.zil.replay_disable

There may be others, but this is a good start.

I fear this change may be too cross-cutting, feel free to break it into several digestible commits if necessary. Nevertheless, no functional changes are intended.

NOTE: Do not MFC to stable/12.

30	The ARC values should be unsigned long (tangential to the change).

commit 2bdf61ca29d075559a8531962ec4e5f09d1105ed
Author: Andre Oppermann <andre@FreeBSD.org>
Date:   Sat Oct 20 12:53:14 2012 +0000

    Hide the unfortunate named sysctl kern.ipc.somaxconn from sysctl -a
    output and replace it with a new visible sysctl kern.ipc.acceptqueue
    of the same functionality.  It specifies the maximum length of the
    accept queue on a listen socket.
    
    The old kern.ipc.somaxconn remains available for reading and writing
    for compatibility reasons so that existing programs, scripts and
    configurations continue to work.  There no plans to ever remove the
    orginal and now hidden kern.ipc.somaxconn.

This one can be MFC'd to 12
