57cd14f194 AUTHORS: improve markdown output
The markdown output for the maintainers, authors and contributors list
was wrapped in a single line and it was difficult to read. I've created
an unordered list to get a better output. On top of that I've also added
myself as a maintainer.

9a780cf22b Make libsubid more easily usable from C++
C++ requires extern "C" linkage specification to call functions from a C
library. Enclose the function definitions in subid.h in an extern "C"
block if compiling in C++ mode to achieve this.

f1f1678e13 useradd: modify check ID range for system users
useradd warns that a system user ID less than SYS_UID_MIN is outside the
expected range, even though that ID has been specifically selected with
the "-u" option.

In my opinion all the user ID's below SYS_UID_MAX are for the system,
thus I change the condition to take that into account.

fd5945e533 Use 'void' instead of 'RETSIGTYPE'. Use 'sighandler_t' too.
C89 and POSIX.1-2001 define signal(2) as returning a pointer to a
function returning 'void'.  K&R C signal(2) signature is obsolete.
Use 'void' directly.

Also, instead of writing the function pointer type explicitly, use
POSIX's 'sighandler_t'.

BTW, the function is defined by SVr4, 4.3BSD, and POSIX.1-2001, so

POSIX.1-2008 marks it as obsolete, but only because
clock_gettime(2) provides more precission.  Since gettimeofday(3)
is in use by many big projects, and it has no obvious dangers,
it's likely that it will continue to exist even if it's outside of
the POSIX standard.

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.
