This creates the /data/misc/apexrollback directory which will
hold snapshots of DE_sys apex data directories (i.e. it will
hold backups of data from /data/misc/apexdata for particular
apexes).

This creates the directory /data/misc/apexdata, at the same time as other
directories under /data/misc. Then, when apexd has finished activating
APEXes, a directory is created under /data/misc/apexdata for every
APEX, with the same name as the APEX module name.
See go/apex-data-directories.
APEXes are discovered by scanning the /apex directory. It may be better
to delegate this process to a library, but it is proposed to defer that
change to a future CL.

Run this process as early as possible in the boot -- right
after its config has been parsed from the apex. This ensures
the sdk prop is set as early as it can be, should some other
early process need to look at it.
Note: this is unlikely to be the permanent way this gets run,
as it's only needed when apexes update.

* changes:
init: Add support for native service registration with lmkd
lmkd: Support process types when registering a process
lmkd: Add library function to unregister a process
lmkd: Prepare lmkd to support connection from init process
lmkd: Restrict process record modifications to the client that created it
init should be able to register native services with lmkd so that they
can be killed when needed. Only processes with oom_score_adjust not
equal to the default -1000 will be registered with lmkd because with the
score that low the process is unkillable anyway.
Inform lmkd when a registered process is killed so that the record can be
removed.
Change init.rc to start lmkd during init phase so that it is there to
register other services.
Replace hardcoded oom_score_adj values with appropriate definitions.

We are going to teamfood userspace reboot soon, and in order to gather
as much data as possible we are fine with ignoring checkpointing for the
devices with ext4 (teamfood will be a very limited set of people that
are aware what they've signed for).
As result of this, we don't need to reset vold and kill zram backing
device. Added a TODO to restore that functionality if needed.
Since I was there, fixed yet another typo in userspace-reboot-resume -_-

* Refactored code around stopping services a little bit to reuse it
between full reboot and userspace reboot.
* Add a scope_guard to fallback to full reboot in case userspace reboot
fails.
* In case of userspace reboot init will also wait for services to be
terminated/killed and log the ones that didn't react to
SIGTERM/SIGKILL in time.
* If some of the services didn't react to SIGKILL, fail userspace reboot.

This CL only draws boundaries between userspace and full reboots, and
adds some functionality that will be required for userspace reboot:
* Whenever device is shutting down is now controlled in reboot.cpp,
since during userspace reboot this state can change.
* Now it's also possible to restart handling of control messages inside
property service. In case of userspace reboot, init will restart it
after stopping post-data services.
* New userspace-reboot-requested trigger is added similar to shutdown
one for full reboot.

This change is part of a topic that moves the recovery resources from the
system partition to the vendor partition, if it exists, or the vendor directory
on the system partition otherwise. The recovery resources are moving from the
system image to the vendor partition so that a single system image may be used
with either an A/B or a non-A/B vendor image. The topic removes a delta in the
system image that prevented such reuse in the past.
The recovery resources that are moving are involved with updating the recovery
partition after an update. In a non-A/B configuration, the system boots from
the recovery partition, updates the other partitions (system, vendor, etc.)
Then, the next time the system boots normally, a script updates the recovery
partition (if necessary). This script, the executables it invokes, and the data
files that it uses were previously on the system partition. The resources that
are moving include the following.
* install-recovery.sh
* applypatch
* recovery-resource.dat (if present)
* recovery-from-boot.p (if present)
This change moves the recovery resources to vendor in libcutils/fs_config.cpp
and removes the flash_recovery service from rootdir/init.rc. This service moved
to a vendor init.rc file in bootable/recovery/applypatch.

libcrypto performs a self test when it is loaded, unless
a marker file /dev/boringssl/selftest/[hash] exists which
indicates that the self test has already successfully
completed since the last time the device was booted.
Before this CL topic, libcrypto attempted to create the
marker file when the self test successfully completed.
On Android, dedicated boringssl_self_test{32,64} binaries
are run early during boot and are the only binaries
(apart from init and vendor_int) that have permission to
create these files.
Another CL in this topic stops the boringssl self test
creating a marker file unless the environment variable
BORINGSSL_SELF_TEST_CREATE_FLAG is set to a nonempty value.
This CL sets that value to "true" when running the dedicated
self test binaries, but not for other binaries. This has
the effect that other binaries that run the self test
early during boot (before the dedicated self test binaries
have created the marker files) and which run the self test
will no longer attempt to create the marker file, which
SELinux would have denied anyway.

This replaces the recently added `exec_reboot_on_failure` builtin, since
it'll be cleaner to extend service definitions than extending `exec`.
This is in line with what we decided when adding `exec_start` instead
of extending `exec` to add parameters for priority.
Test: `exec_start` a service with a reboot_on_failure option and watch
the system reboot appropriately when the service is not found and when
the service terminates with a non-zero exit code.

This should ensure that the self tests run before any other binaries
that load libcrypto and which would otherwise run into SELinux denials
trying to create the marker file /dev/boringssl/selftest/[hash]
The invocation of the self test binaries from the Conscrypt apex
requires the apex to be mounted so it remains at a later point in
the boot process.
