191f04f7dc Use *array() allocation functions where appropriate
This prevents overflow from multiplication.

45c0003e53 Use reallocf(3) instead of its pattern
In addition, don't set local variables just before return.

0e1d017993 Rely on realloc(NULL, ...) being equivalent to malloc(...)
This is guaranteed by ISO C.  Now that we require ISO C (and even POSIX)
to compile, we can simplify this code.

62172f6fb5 Call NULL by its name
In variadic functions we still do the cast.  In POSIX, it's not
necessary, since NULL is required to be of type 'void *', and 'void *'
is guaranteed to have the same alignment and representation as 'char *'.
However, since ISO C still doesn't mandate that, and moreover they're
doing dubious stuff by adding nullptr, let's be on the cautious side.
Also, C++ requires that NULL is _not_ 'void *', but either plain 0 or
some magic stuff.

0d9799de04 Don't test for NULL before calling free(3)
free(3) accepts NULL, since the oldest ISO C.  I guess the
paranoid code was taking care of prehistoric implementations of
free(3).  I've never known of an implementation that doesn't
conform to this, so let's simplify this.

Remove xfree(3), which was effectively an equivalent of free(3).

d4fc74e43c * lib/sgetpwent.c, lib/sgetgrent.c: Use get_uid and get_gid to
validate the UIDs or GIDs instead of atoi/strtol.

f86b2704d5 * lib/groupio.h, lib/prototypes.h, lib/pwio.h, lib/sgetgrent.c:
Include <sys/types.h> before <pwd.h> and <grp.h>. It is necessary
	for the definition of uid_t and gid_t.
	* lib/pwmem.c: do not include <pwd.h>, "pwio.h" is sufficient
	here.
