Get rid of update. Make man page installation work with our scheme

(and rename a few in the process).

+.Sh NAME
+.Nm arp
+.Nd Address Resolution Protocol
+.Sh SYNOPSIS
+.Em "pseudo-device ether"
+.Sh DESCRIPTION
+The Address Resolution Protocol (ARP) is a protocol used to dynamically
+map between Internet host addresses and 10Mb/s Ethernet addresses.
+It is used by all the 10Mb/s Ethernet interface drivers.
+It is not specific to Internet protocols or to 10Mb/s Ethernet,
+but this implementation currently supports only that combination.
+.Pp
+ARP caches Internet-Ethernet address mappings. 
+When an interface requests a mapping for an address not in the cache,
+ARP queues the message which requires the mapping and broadcasts
+a message on the associated network requesting the address mapping.
+If a response is provided, the new mapping is cached and any pending
+message is transmitted.
+ARP will queue at most one packet while waiting for a response to a
+mapping request;
+only the most recently ``transmitted'' packet is kept.
+If the target host does not respond after several requests,
+the host is considered to be down for a short period (normally 20 seconds),
+allowing an error to be returned to transmission attempts during this
+interval.
+The error is
+.Li EHOSTDOWN
+for a non-responding destination host, and
+.Li EHOSTUNREACH
+for a non-responding router.
+.Pp
+The ARP cache is stored in the system routing table as
+dynamically-created host routes.
+The route to a directly-attached Ethernet network is installed as a
+.Dq cloning
+route (one with the
+.Li RTF_CLONING
+flag set),
+causing routes to individual hosts on that network to be created on
+demand.
+These routes time out periodically (normally 20 minutes after validated;
+entries are not validated when not in use).
+An entry for a host which is not responding is a
+.Dq reject
+route (one with the
+.Li RTF_REJECT
+flag set).
+.Pp
+ARP entries may be added, deleted or changed with the
+.Xr arp 8
+utility.
+Manually-added entries may be temporary or permanent,
+and may be
+.Dq published ,
+in which case the system will respond to ARP requests for that host
+as if it were the target of the request.
+.Pp
+In the past,
+ARP was used to negotiate the use of a trailer encapsulation.
+This is no longer supported.
+.Pp
+ARP watches passively for hosts impersonating the local host (i.e. a host
+which responds to an ARP mapping request for the local host's address).
+.Sh DIAGNOSTICS
+.Em "duplicate IP address %x!! sent from ethernet address: %x:%x:%x:%x:%x:%x."
+ARP has discovered another host on the local network which responds to
+mapping requests for its own Internet address with a different Ethernet
+address, generally indicating that two hosts are attempting to use the
+same Internet address.
