I added a third value for kern.logsigexit to mean 'auto' as an abundance of caution, but I don't know how much it matters -- that can be easily consolidated back to boolean-ish. This is primarily targeted towards people running test suites under CI (e.g. buildbot, jenkins). Oftentimes tests entail segfaults that are expected, and logs get spammed -- this can be particularly high volume depending on the application. Per-process control of this behavior is desirable because they may still want to be logging legitimate segfaults, so the system-wide atomic bomb kern.logsigexit=0 is not a great option. This adds a process flag to disable it, controllable via procctl(2)/proccontrol(1); the latter knows it as "sigexitlog" due to its length, but it's referred to almost everywhere else as "sigexit_log."
