fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

2279a9a428 When -n is specified, don't make bogus DNS queries. Instead,
when -n is specified more than once, hostnames stored in utmp
are attempted to resolve to display them as network addresses.

630a02daae Fix libxo output from uptime command
the libxo output for uptime returned multiple 'uptime' keys, one each for number of days, hours, and minutes of uptime.
This is invalid JSON.
This patch makes the output the raw number of seconds, as well as adding keys for the individual unit values
A string of the original output from the plain-text uptime command is also added

check that the resulting stat structure belongs to a character device.

1131779fb3 Port w(1) to utmpx.
Let it print "-" when the TTY string is empty. In this case, it must
also make sure it doesn't match processes who also have no controlling
TTY. Otherwise it will print random kernel processes when trying to pick
the best matching process.

Eventually it should look at the value of ut_pid as well.

dc65bcacb2 Let w(1) use utmpx.
We don't have UT_*SIZE anymore. One of the reasons for that is because
all strings are null terminated, there is no need for apps to copy
strings out of the utmpx structure. This means we can define W_DISP*SIZE
lengths for all columns.

While there, adjust the sizes a little. Steal some bytes from the
username column, while extending the hostname column quite a bit.

5b718312b7 When -n is specified, don't attempt to turn hostnames found in utmp
into addresses as we have no idea what address family they belong to.

When -n is not specified, resolve IPv6 as well as IPv4 addresses found
in the host field of utmp.  Use realhostname_sa() to resolve addresses
(the old code was wrong).

Rename ``x'' to ``x_suffix'' to avoid confusion.

Hard code the host column width to 16 (against the imminent increase
of UT_HOSTSIZE in utmp.h).

1f7d250182 Change the proc information returned from the kernel so that it
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.
