It is Undefined Behavior to declare errno (see NOTES in its manual page).
Instead of using the errno dummy declaration, use one that doesn't need
a comment.

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().

* libmisc/audit_help.c: Replace an fprintf() by fputs().

Return -1 otherwise.

* 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)).
shadow_audit_result for the result argument of audit_logger().
This permits stronger type checking and a better readability of
the results (SHADOW_AUDIT_FAILURE/SHADOW_AUDIT_SUCCESS constants).
* src/groupadd.c, src/groupdel.c, src/useradd.c, src/userdel.c:
Use the SHADOW_AUDIT_FAILURE/SHADOW_AUDIT_SUCCESS results instead
of 0 or 1 in audit_logger().
* libmisc/audit_help.c: Include prototypes.h to get the prototype
of audit_help_open.
* libmisc/salt.c: Use booleans instead of negating integers.
* src/passwd.c: Declare the check_selinux_access prototype and
avoid name clashes (change_user -> changed_user; change_uid ->
changed_uid; access -> requested_access)
