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.

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.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

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).
session start time. This is useful when looking at old or long-running

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.
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.
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)
: ru ttyv7 Mon May 28 12:45 - 12:46 (00:00:25)

Otherwise, an additional blank line is inserted.
