Switch from /data/misc/reboot/last_reboot_reason to persistent Android property persist.sys.boot.reason for indicating why the device is rebooted or shutdown. persist.sys.boot.reason has a standard as outlined in b/63736262 and the associated investigation. Made adjustments to the values so that we did not create a problem even before we started. Compliance is part of the tests in boot_reason_test.sh. Test: system/core/bootstat/boot_reason_test.sh Bug: 64687998 Change-Id: I812c55a12faf7cb7ff92101009be058ad9958d07
