Let's lot at LOG_NOTICE about any processes that we are going to SIGKILL/SIGABRT because clean termination of them didn't work. This turns the various boolean flag parameters to cg_kill(), cg_migrate() and related calls into a single binary flags parameter, simply because the function now gained even more parameters and the parameter listed shouldn't get too long. Logging for killing processes is done either when the kill signal is SIGABRT or SIGKILL, or on explicit request if KILL_TERMINATE_AND_LOG instead of LOG_TERMINATE is passed. This isn't used yet in this patch, but is made use of in a later patch.
