Replace struct timeval in header with struct timespec.
To differentiate header formats, add a new KTR_VERSIONED flag
set in the header type field similar to the existing KTRDROP flag.
To make it easier to extend ktrace headers in the future,
extend the existing header with a version field (version 0 is
reserved for older records without KTR_VERSIONED) as well as
new fields holding the thread ID and CPU ID.

This allows for easy copy-and-paste of a unix(4) peer name for lookup.
With current implementation it is guaranteed that a peer listed could be

Kernel provides us with enough information to display all possible
connections between UNIX sockets.
o Store unp_conn, xu_firstref and xu_nextref in the faddr of a UNIX sock.
o Build tree of file descriptors, indexed by the socket pointer.
o In displaysock() print out all possible information:
1) if socket is bound, print name of this socket
2) if socket has connected to a peer with a name, print peers name
3) if socket has connected to a peer without a name, print [pid fd]
4) if a bound socket has received connections, print list of them
as [pid fd]
Previously, only 1) either 2) were printed.

o Use tree to lookup by socket kvaddr. The size of hash is too big for a
small virtual machine and at the same time too little for a large
production server. A tree would better fit here.
o For those pcbs, that don't have a socket associated, use a list.
o Provide a second tree to lookup by pcb kvaddr. These removes full hash
traversal when printing every unix(4) socket.

The field for interface names for netstat -i was 5 characters by
default, which is no longer sufficient with names like "vlan1234"
and "vtnet0". netstat -iW computed the necessary field width, but
also enlarged the address field by a lot (especially with IPv6 enabled).
Make netstat -i compute the field width for interface names with or
without -W. Note that the existing default output does not fit in
80 columns in any case. Update the man page accordingly, documenting
the remaining effect of -W with -i. Also add -W to the list of
General Options, as there are numerous pointers to this.

The current situation is fairly confusing, where an integer is interpreted
as a percent until you slap a decimal on it and magically it becomes an
absolute value.
Let's have a flag day in 14.0 and remove this shim entirely. Setting with
percent can still be useful, so allow a trailing '%' to indicate as such.
As a side effect, we tighten down the format allowed in the volume a little
bit by ensuring there's no trailing garbage after the value once it's
separated into left and right components.

This version adds support for command line editing and history using
the libedit or readline libraries in addition to the line editing
features available in previous versions.
The version in the base system is configured to use libedit.
This allows to choose between emacs and vi line editing commands and
to use command overrides via a ~/.editrc file.

Mbufs leak when manually removing incomplete NDP records with pending packet via ndp -d.
It happens because lltable_drop_entry_queue() rely on `la_numheld`
counter when dropping NDP entries (lles). It turned out NDP code never
increased `la_numheld`, so the actual free never happened.
Fix the issue by introducing unified lltable_append_entry_queue(),
common for both ARP and NDP code, properly addressing packet queue
maintenance.

Commit 5218d82c81 added a new NFSv4.1/4.2 procedure called
AppendWrite that uses a Verify to avoid a separate Getattr RPC
for the common case where the client knows the correct file
size for O_APPEND writes.
This patch modifies nfsstat so that it displays a count of
these new RPCs for the "-E -c" option.
With M_EXTPG mbufs these two counters already do not represent the
reality. As we are moving towards protocol independent socket buffers,
which may not even use mbufs at all, the counters become less and less
relevant. The only userland seeing them was 'netstat -x'.
