It is Undefined Behavior to declare errno (see NOTES in its manual page).
Instead of using the errno dummy declaration, use one that doesn't need
a comment.

This is shorter to write than 'unsigned long int', so we can collapse
some lines. It is guaranteed by C99.

The buffers have a size of 512 (see xmalloc() above), which is what
snprintf(3) expects.

Previous commits, to keep readability of the diffs, left the code that
was previously wrapped by preprocessor coditionals untouched. Apply
some minor cosmetic changes to merge it in the surrounding code.

- USER_NAME_MAX_LENGTH was being calculated in terms of utmpx. Do it
in terms of utmp.
- Remove utmpx support from the whishlist.
- Remove unused tests about utmpx members.

On Linux, utmpx and utmp are identical. However, documentation (manual
pages) covers utmp, and just says about utmpx that it's identical to
utmp. It seems that it's preferred to use utmp, at least by reading the
manual pages.
Moreover, we were defaulting to utmp (utmpx had to be explicitly enabled
at configuration time). So, it seems safer to just make it permanent,
which should not affect default builds.

We already made that assumption in commit b47aa1e9aa. While the
header is not required by POSIX (it is an XSI extension), it is defined
in systems that are of interest to this project (GNU/Linux).
Fixes: b47aa1e9aa ("Assume <utmpx.h> exists")

We don't know what it was for. If anyone cares, it's in git history.
In my distro, there seem to be no traces of it:

When useradd sends its ADD_USER event, it is filling in the id field. This is not yet written to disk. When auditd sees the event and the log format is enriched, auditd tries to lookup the user name but it does not exist. This causes the event to never be resolvable since ausearch relies on the lookup information attached by auditd.
The fix is to not send the id information for any event until after close_files() is called. Just the acct field is all that is

In a previous commit, we made USE_TERMIOS unconditionally defined.
Let's just remove it, and remove the condition everywhere.

I don't know for sure what that is, but it's redefining setlocale(3)
and LC_ALL, which is are defined by C99, so it's supect of being some
variety of an extinct dynosaur. Maybe related to the Dodo.

The function is obsolete. It is recommended to use getrlimit(2) instead
(see the manual page for ulimit(3) or the POSIX manual for it). Since
getrlimit(2) is required by POSIX.1-2001, we can rely on it.
