Thermal shutdown could be due to tskin temperature or
battery temperature. Pass reason while rebooting the
system to reflect properly in boot.reason
Bug: 238464124
Test: Build and boot on device. Check reboot reason
for thermal shutdown and battery thermal shutdown with
thermal warmreset enabled.

The critical services can now using the interface `critical
[window=<fatal crash window mins>] [target=<fatal reboot target>]` to
setup the timing window that when there are more than 4 crashes in it,
the init will regard it as a fatal system error and reboot the system.
Config `window=${zygote.critical_window.minute:-off}' and
`target=zygote-fatal' for all system-server services, so platform that
configures ro.boot.zygote_critical_window can escape the system-server
crash-loop via init fatal handler.

The exit of init panics the system *after* process context (mm, stack,
...etc.) are recycled, according to Linux kernel's 'do_exit'
implementation. To preserve most init process context for debugging,
triggers the panic via proc-sysrq explicitly.
Note: after this change, there will be no "Attempt to kill init" panic
when androidboot.init_fatal_panic is set.
Test: Insert data abort fault in init, the full process context is
preserved in memory dump captured after panic.

It wasn't clear to me why init was rebooting until I saw that it was
SIGABRT, which then made me read through earlier log spam to work out
what was actually unhappy (the SELinux compiler, in my case).
Test: worked out why init was rebooting my device

Currently, if init encounters a fatal issues it reboots to fastboot
but this may be not desirable in all cases, especially the case of
critical services crashing. Therefore this change adds the ability
for vendors to customize the reboot target via the
androidboot.init_fatal_reboot_target= kernel command line.
This applies to all LOG(FATAL) messages as well as fatal signals in
userdebug/eng builds, except for signals before logging is enabled in
first stage init.
Bug: 121006328
Test: device reboots to configurable target with LOG(FATAL)
Test: device reboots to configurable target after a segfault in the
various stages of init
Test: device reboots to fastboot without a configured target

Dump init stacks when aborting either due to LOG(FATAL) or in
userdebug/eng builds due to signals, including signals from
sanitizers.
Doesn't work for static first stage init yet, b/133450393 tracks
that.
Also, ensure that LOG(FATAL) in child processes calls abort() in all
stages of init, not just 2nd stage init.
Bug: 131747478
Test: abort init in various ways and see stacks
Test: hang or crash in backtrace handler and see child reboot

This is a baseline for splitting init first and second stage into
their own executables.
