It has been a requirement since at least C90, according to tm(3type).

- 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")

The function is obsolete.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.

ISO C99 requires <locale.h>.
Other files in the project already include <locale.h> unconditionally,
so it's reasonable to assume that it is always available.

The missing #include <gshadow.h> causes the configure check to fail
spuriously, resulting in HAVE_SHADOWGRP not being defined even
on systems that actually have sgetsgent (such as current glibc).
Version 1.19.1 was released in June 2014.
