9e788adf56 Remove AC_HEADER_SYS_WAIT
GNU autoconf documentation marks this macro as obsolescent, as
current systems are compatible with POSIX.

Simplify code to unconditionally include <sys/wait.h>, and don't
redefine WIFEXITSTATUS() and WIFEXITED(), since they are mandated
by POSIX.

79e28694ef Remove AC_HEADER_DIRENT
POSIX.1-2001 defines 'struct dirent' in <dirent.h>.  It replaces
the old 'struct direct' found in BSDs.  All of the systems that I
checked (including FreeBSD, NetBSD, and OpenBSD), now provide
<dirent.h> with 'struct dirent', as mandated by POSIX.

Since autoconf first checks <dirent.h> and only if it's missing it
checks other header files, it's clear that it will always find
<dirent.h>, so let's simplify.

GNU autoconf documentation declares this macro as obsolescent, and
acknowledges that all current systems with directory libraries
have <dirent.h>:

7a799ebb2c Ensure memory cleaning
Compilers are allowed to and do optimize memset(3) calls away for
pointers not accessed in the future. Since the memzero wrappers purpose
is exactly to unconditionally override memory (e.g. for stored
passwords) do not implement via regular memset(3), but via either
memset_s(3), explicit_bzero(3) or a hand written implementation using
volatile pointers.

44126d85ee Remove definition of ISDIGIT_LOCALE(c)
It wasn't being used at all.  Let's remove it.

Use isdigit(3) directly in comments that referenced it.

Also, in those comments, remove an outdated reference to the fact
that ISDIGIT_LOCALE(c) might evaluate its argument more than once,
which could be true a few commits ago, until
IN_CTYPE_DEFINITION(c) was removed.  Previously, the definition
for ISDIGIT_LOCALE(c) was:

 #if defined (STDC_HEADERS) || (!defined (isascii) && !defined (HAVE_ISASCII))
 # define IN_CTYPE_DOMAIN(c) 1
 #else
 # define IN_CTYPE_DOMAIN(c) isascii(c)
 #endif

 #define ISDIGIT_LOCALE(c) (IN_CTYPE_DOMAIN (c) && isdigit (c))

Which could evaluate 'c' twice on pre-C89 systems (which I hope
don't exist nowadays).

45d2e6dff0 Remove IN_CTYPE_DOMAIN, which was always true
The recent removal of STDC_HEADERS made IN_CTYPE_DOMAIN be defined
to 1 unconditionally.  Remove the now unnecessary definition, and
propagate its truthness to expressions where it was used.

4e1afcd662 Assume STDC_HEADERS will always be defined
We're in 2021.  C89 is everywhere; in fact, there are many other
assumptions in the code that wouldn't probably hold on
pre-standard C environments.  Let's simplify and assume that C89
is available.

The specific assumptions are that:
- <string.h>, and <stdlib.h> are available
- strchr(3), strrchr(3), and strtok(3) are available
- isalpha(3), isspace(3), isdigit(3), and isupper(3) are available

I think we can safely assume we have all of those.

b7e12ec04e Remove HAVE_MEMSET ifdefs
memset(3) has been in standard C since C89.  It is also in
POSIX.1-2001, in SVr4, and in 4.3BSD (see memset(3) and memset(3p)).
We can assume that this function is always available.
