The new option is named check_unreachable_on_signal. It is meant to duplicate dumpsys meminfo --unreachable <PID> for non-java processes. When enabled, a user can send a signal to a process which will trigger the unreachable check on the next allocation call. Added new unit tests. Test: New unit tests pass. Test: Enabled for the entire system, then dumped on the netd Test: process and also system_server. Change-Id: I73561b408a947a11ce21a211b065d59fcc39097b
