593899 - adding specific ACI causes very large mem allocate request
    
    https://bugzilla.redhat.com/show_bug.cgi?id=593899
    
    Additional fix: if a target value is double quoted followed by
    trailing spaces, the double quotes were not correctly handled.
    Sample failed case:
    aci: ( target = "ldap:///ou=organizationalUnit, o=test_ACIs.com" )
                                                                    ^
    Changed to call __acl_strip_trailing_space to remove them.
