bzero() function has been deprecated for a long time.
In samba it is replaced with memset(). But samba also
provides common memory-zeroing macros, like ZERO_STRUCT().
In all places where bzero() is used, it actually meant to
zero a structure or an array.
So replace these bzero() calls with ZERO_STRUCT() or
ZERO_ARRAY() as appropriate, and remove bzero() replacement
and testing entirely.
While at it, also stop checking for presence of memset() -
this function is standard for a very long time, and the
only conditional where HAVE_MEMSET were used, was to
provide replacement for bzero() - in all other places
memset() is used unconditionally.

it is present if HAVE_LINUX_IOCTL is defined.

We need a genuine boolean type, as otherwise expressions like
bool foo = (4 & 4);
if (foo == true) {
exit(1);
} else {
exit(2);
}
could evaluate differently on non-modern platforms, and
that would be a real pain to debug.

Use of Samba with plaintext authenticaiton is incredibly rare, even more
rare is plaintext authentication on systems without a crypt() call and
where DES based crypt() would be the right thing to do.
Remove this additional cryptographic code per our current efforts
to rely entirely on external libraries instead.

This fixes the build of python bindings, which use memset_s()
(via ZERO_STRUCT).
In python bindings Python.h needs to be the first header, which means
is already includes string.h. Defining __STDC_WANT_LIB_EXT1__ in
replace.h is too late in that case.
This fixes the --check-c-compiler=gcc --picky-developer on FreeBSD 12.

Provide a XSI-compliant strerror_r on GNU based systems.
The default GNU strerror_r is not XSI-compliant, this patch wraps the
GNU-specific call in an XSI-compliant wrapper.
This reverts 18ed32ce0821d11c0c06d82c07ba1c27b0c2b886 which tried to

There is closefrom in some BSDs, but Linux ships this only as part
of libbsd. Add a new implementation of it in libreplace. The one in
libbsd of jessie and upstream differ and it has for example optimizations
for FreeBSD, but it gets some of the array calculations slightly wrong
from my point of view. If you want those, use libbsd. This replacement
is optimized on Linux only looking at /proc/self/fd/, everything else
would do the OPEN_MAX brute force fallback.

On arm platforms incrementing a variable is not
an atomic operation, so may be interrupted by
signal processing (if a signal interrupts another
signal handler).
Use compiler built-ins to make this atomic.
__sync_fetch_and_add() works on gcc, llvm,
IBM xlC on AIX, and Intel icc (10.1 and
above).
atomic_add_32() works on Oracle Solaris.
Based on an inital patch from kamei@osstech.co.jp.
