bddcd9b095 Remove superfluous casts
-  Every non-const pointer converts automatically to void *.
-  Every pointer converts automatically to void *.
-  void * converts to any other pointer.
-  const void * converts to any other const pointer.
-  Integer variables convert to each other.

I changed the declaration of a few variables in order to allow removing
a cast.

However, I didn't attempt to edit casts inside comparisons, since they
are very delicate.  I also kept casts in variadic functions, since they
are necessary, and in allocation functions, because I have other plans
for them.

I also changed a few casts to int that are better as ptrdiff_t.

This change has triggered some warnings about const correctness issues,
which have also been fixed in this patch (see for example src/login.c).

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.

a51954203e * lib/prototypes.h, libmisc/addgrps.c: restrict add_groups() to
ifndef USE_PAM.
	* lib/prototypes.h: Remove the declaration of add_cons_grps(). The
	function does not exist.
	* libmisc/age.c (setup_uid_gid): is_console is never set ifndef
	USE_PAM. Change the prototype of setup_uid_gid() when USE_PAM is
	not defined. This permits to remove add_groups from PAM builds.
	setup_uid_gid is already subject to HAVE_INITGROUPS.
	* libmisc/pwd2spwd.c (pwd_to_spwd): pwd_to_spwd() is not used in
	PAM builds.

28a9441f4f Replace printf by puts for fixed strings. This would avoid issues caused
by formats introduced in translated strings.
