[PATCH V4 (was V6)] generalize audit_del_rule

[Richard Guy Briggs]

This patch was split out from the audit by executable path patch set due to the
potential to use it elsewhere.

In particular, some questions came up while assessing the potential for code
reuse:

	Why does audit_remove_parent_watches() not call audit_del_rule() for
	each entry found?
                Is audit_signals not properly decremented?
                Is audit_n_rules not properly decremented?

        Why does kill_rules() not call audit_del_rule() for each entry found?
                Is audit_signals not properly decremented?
                Is audit_n_rules not properly decremented?
