Alejandro Colomar 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).

Serge Hallyn 2b22a6909d libsubid: don't print error messages on stderr by default 
Closes #325

Add a new subid_init() function which can be used to specify the
stream on which error messages should be printed.  (If you want to
get fancy you can redirect that to memory :)  If subid_init() is
not called, use stderr.  If NULL is passed, then /dev/null will
be used.

This patch also fixes up the 'Prog', which previously had to be
defined by any program linking against libsubid.  Now, by default
in libsubid it will show (subid).  Once subid_init() is called,
it will use the first variable passed to subid_init().

nekral-guest 1b0a32d71c * libmisc/cleanup_group.c: Fix compilation when compiled without 
shadow group support.

nekral-guest 5b8ff14caf * libmisc/audit_help.c: Added audit_logger_message() to log 
messages not related to an account.
	* lib/prototypes.h, libmisc/cleanup.c, libmisc/cleanup_group.c,
	libmisc/cleanup_user.c, libmisc/Makefile.am: Added stack of
	cleanup functions to be executed on exit.
	* NEWS, src/groupadd.c, src/groupdel.c, src/groupmod.c: Only
	report success to audit and syslog when the changes are committed
	to the system. Do not log failure for on-memory changes to audit
	or syslog. Make sure failures and inconsistencies will be reported
	in case of unexpected failures (e.g. malloc failures). Only
	specify an audit message if it is not implicitly implied by the
	type argument. Removed fail_exit (replaced by atexit(do_cleanups)).
