PR/56013: Kouichi Hashikawa: Move setutent/setutxent right before the loops.

use memcpy() for strings that are not C strings.
destinations are already sufficiently sized and nul terminated.

revert previous; i meant to test first and if you read the comment
immediately above, you can see it is done safely and on purpose.

use destination buffer size not source buffer size for strncpy len.

PR/41313: Chris Spiegel: getutentries() in src/usr.bin/who/utmpentry.c thinks
there are no entries if only one of utmp/utmpx support is selected
mangled && -> ||

branches: 1.16.4;
pass lint.

Clarify how one is supposed to use the pointers returned by getutentries()
(the utmpentry.c code), specifically with respect to who owns them and
when to free them. Now they're owned by utmpentry.c, only. Abolish the
freeutentries() function, which was the wrong abstraction; add instead
endutentries(), which flushes out the internally managed memory.

Update callers as necessary. Some (e.g. talkd) had been leaking memory;
others (e.g. syslogd) had been accidentally freeing and reloading utmp
more often than necessary. There are a couple untidy bits in users and
rwhod that someone should look after sometime, maybe.

Fixes PR bin/35131, which was about talkd's memory leak.

Amplify comments from the previous commit. If xtos misread what was
going on, they can't have been clear enough. (And if xtos misread it,
so will anyone else passing by, and then someone will "fix" it...)

Hopefully this will help. Maybe it should be changed to use memcpy
instead of strncpy after all.

Remove reflexive cargo-cult-style null-termination after strncpy; it is
neither needed nor particularly desirable. Add comments to explain what's
going on, and arrange to fail the build if the sizes of things get out
of whack.

PR/35135: David A. Holland: timespec patches for utmpentry.c

set utmp entry types to user process.

Add support for the majority of the rest of the system V options, although
we don't support some of them. We might add boottime, system clock change
time, in the future, so add the code to do it.

Change -u behaviour to also print PID of process on terminal, and
add -d to print more information from utmpx.
