shadow/libmisc/cleanup_user.c
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)).
