4d8e3eaf9f Don't retrigger bootstat during userspace reboot.
Userspace reboot can be treated as extension of runtime restart: instead
of restarting just system_server, it restarts all post-data services.

Test: adb reboot userspace
Test: checked bootstat didn't run again.
Test: system/core/bootstat/boot_reason_test.sh

4e9c653c93 bootstat: Update boot reason property earlier
bootstat updates boot reason upon boot_complete, however users of the
updated properties e.g. getLastShutdownReason from PowerManager could
be called before boot_complete. This introduces a inconsistency and
racing for those APIs.

In this CL, we change boot reason to be updated at the same time when
zygote starts where persist properties have been loaded already. Also
the initialization of bootloader's boot reason is pulled into post-fs
where all kernel command line arguments have been parsed in init already.

Test: trigger thermal shutdown and see warnings
Test: verify boot reason properties updated correctly post boot

993f65619e Fix performance degradation from BootSequence atom
(partial cherry pick from commit fe3e762b6d)

Adding the boot sequence reported atom in ag/3518079 caused the duration
of bootstat to increase, as seen in b/72864061. I isolated the cause
down to calling BootReasonStrToReason. However, this function also gets
called in ReportBootReason, so I created another function that does the
parsing and sets the system boot reason property, and made
RecordBootReason and statsd logging get that property.

Test: rebooted phone, verified boot events were received in adb shell
logcat -b stats and verified adb shell bootstat -p printed correct
values. Ran timing tests as well on walleye with 20 boots: before this
change, the average was ~150-160ms. After, it was ~80ms.

557a9d4054 bootstat: reduce overall boot time
Run bootstat as a oneshot service rather than as a series of inline
exec commands.  exec commands impact boot time.

Test: cts-tradefed run cts-dev --module CtsBootStatsTestCases

b304f6d4e7 bootstat: introduce sys.boot.reason
Adding functionality to bootstat --record_boot_complete and
--record_boot_reason to initialize sys.boot.reason, the canonical
system boot reason.

Filter out ro.boot.bootreason oem noise into sys.boot.reason.  Add
heuristics to determine what the boot reason is, when otherwise would
be defaulting to the blunt and relatively devoid of detail catch-all
reboot reasons ("reboot", "shutdown", "cold", "warm", "hard").

boot_reason_test.sh is also a compliance test.

Test: boot_reason_test.sh all

c3ad75be84 bootstat: switch from root.root to system.log
bootstat does not need root uid and root gid permissions to perform
its tasks.  It appears that system uid and log gid are adequate and
appropriate.

c08e996ac8 bootstat: Disambiguate boot time on encrypted devices.
This change introduces new metrics to discern boot time on encrypted devices:
* post_decrypt_time_elapsed
* boot_decryption_complete
* boot_complete_post_decrypt
* boot_complete_no_encryption

boot events in the LOCAL_INIT_RC file, bootstat.rc.
