0806dd9238 Remove stale references to utmp(5) and its corresponding filenames.
I removed utmp and its manpage, but not other manpages referring to it.

6628ca0a98 Make last(1) display the full log file.
I must have misread when I ported the original last(1) source code.
Instead of only processing the last 1024 entries, it reads them in in
chucks of 1024 entries at a time.

Unfortunately we cannot walk through the log file in reverse order,
which means we have to allocate a piece of memory to hold all the
entries. Call realloc() for each 128 entries we read.

561f61e25d Port last(1) to use utmpx.
Basically there are three major things I changed about last(1):

- It should use ut_type instead of determining by hand what type of
  record was given.
- It should now keep track of ut_id's instead of TTYs. This means the
  ttylist has been renamed to the idlist, storing all the ut_id's it has
  processed until the next reboot.
- I've removed the signal handler. Because our wtmp is rotated so often,
  it makes little sense. Even on a simple piece of hardware it should be
  capable of grinding through megabytes of logs in a second.

47bca8b02c Clean up malloc(3)'s argument. Remove casts which do nothing when we're
using sizeof() anyway.  Use slightly more consistent (per-file) error
reporting for malloc(3) returning NULL.  If "malloc failed" was being printed,
don't use err(3).  If a NULL format is being used, use err(3).  In one case
errx(3) was being used with strerror(3), so just use err(3).

2e7a4024ff Oops, unbreak the -d and -<n> options. The `snapfound' variable
needs to be retained across entries, and we need to exit(), not
return from doentry() when `maxrec' reaches 0. Move the code for
processing `maxrec' into printentry() for simplicity.

170ac683f2 I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions.  e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard.  They will eventually be replaced when a real standard
comes out of committee.

f82078861c The last(1) choked if there were two successive "login" marks
found in wtmp(5) for the same TTY without in-between "logout"
mark.

This may be demonstrated by executing login(1), logging in and
out, and watching the last(1) output on this TTY:

: # last -tv7 -w
: ru      ttyv7              Mon May 28 12:46 - 12:46  (00:00:01)
: ru      ttyv7              Mon May 28 12:45   still logged in

The fix merely takes the second "login" mark as the "logout" for
the first "login" mark, if there were no "logout" mark in-between.
This restores the behavior of last.c,v 1.2:

: # last -tv7 -w
: ru      ttyv7              Mon May 28 12:46 - 12:46  (00:00:01)

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

c83d3f4574 Fixed a bug that caused last(1) to be extremely slow in some cases, and
made other performance improving changes. This improves the performance
of last(1) by as much as 32 times in some cases, and in more typical cases
is about twice as fast.
Added a BUGS section to the manual page to describe the behavior of last(1)
when a login shell terminates abnormally (and thus doesn't write a logout
record to the wtmp file).
