[kernel][oom] Use "halt token" to coordinate concurrent reboots This change fixes a bug where an already in progress OOM reboot could be superseded by some other reboot operation (e.g. graceful reboot via syscall or critical job termination). Introduce the concept of a halt token that must be obtained prior to halting the system. Change existing non-panic code paths to acquire the halt token. If a code path fails to acquire the token, it must sleep, spin, or return depending on the context and resources (think locks) it holds. Add TestOOMSignalBeforeCriticalProcess test.
