Increase size of the NETLINK_KOBJECT_UEVENT socket receive buffer to

NIAP certification requires that all cryptographic functions
undergo a self-test during startup to demonstrate correct
operation. This change adds such a check.
If the check fails, it will prevent the device from booting
by rebooting into the bootloader.
Bug: 119826244
Test: Built for walleye. After device booted examined dmesg and
observed logs from init showing that the new task did
start. Further, when BoringSSL is built to fail its self
check the device did stop during a normal boot and enter
the bootloader, and did so before the boot animation stopped.

The first split of 1st/2nd stage init went a bit overboard, since it
split these even in the case of the recovery image and system-as-root,
which don't actually need the split. This change simplifies this a
bit:
system-as-root and recovery have a single combined /system/bin/init
and a symlink from /init to it.
non-system-as-root has a separate first stage init at /init on the
first stage ramdisk and a combined /system/bin/init on system.img.
Two particular benefits from this:
1) Removal of the rsync of TARGET_RAMDISK_OUT to the recovery image
2) Decrease of overall space on the recovery image since it won't have
a statically linked first stage init
This also unified the various entry points of init to depend entirely
on the arguments passed to it, instead of the hybrid of arguments and
environment variable used previously.

A service with 'updatable' option can be overriden by the same service
definition in APEXes.
/system/etc/init/foo.rc:
service foo /system/bin/foo
updatable
/apex/myapex/etc/init.rc:
service foo /apex/myapex/bin/foo
override
Overriding a non-updatable (i.e. without updatable option) service
from APEXes is prohibited.
When an updatable service is started before APEXes are all activated,
the execution is delayed until when the APEXes are all activated.

When using the recovery image as a trampoline to boot the system,
first chroot from the recovery image to /first_stage_ramdisk, to
minimize differences between these two boot paths.
Primary motivation is due to the fact that the basename of each mount
point is used by device-manager to name its nodes, and the previous
code that created used /system_recovery_mount as the mount point for
system.img broke AVB. Instead of hacking around that issue, this
change unified mounting for the recovery trampoline and true first
stage ramdisk paths.
Change when relanding: the original change skipped the move mount from
/first_stage_ramdisk to / and only did a chroot instead. This was a
mistake that resulted in the subsequent move mount of /system to / to
mount over the '/' directory instead of moving that mount. This
change uses a bind mount of /first_stage_ramdisk to itself instead of
skipping the first move mount.

Using overlayfs, the system partition may provide files for older
version of vendor partitions by overlaying on the vendor partition.

The memcg.limit_percent option can be used to limit the cgroup's
max RSS to the given value as a percentage of the device's physical
memory. The memcg.limit_property option specifies the name of a
property that can be used to control the cgroup's max RSS. These
new options correspond to the arguments to the limitProcessMemory
function in frameworks/av/media/libmedia/MediaUtils.cpp; this will
allow us to add these options to the rc files for the programs that
call this function and then remove the callers in a later change.
There is also a change in semantics: the memcg.* options now have
an effect on all devices which support memory cgroups, not just
those with ro.config.low_ram or ro.config.per_app_memcg set to true.
This change also brings the semantics in line with the documentation,
so it looks like the previous semantics were unintentional.

If a section header such as 'on' or 'service' has an error with it,

user root

Partial revert of "init: if vendor_init can read a property, let it be
a trigger too" (b35f827c97).
We made a mistake when we allowed vendor init to action on any vendor
or odm property, since when a new SELinux label is created for a
vendor property, vendor_init does not automatically get read
permissions for it.
Recently, we tried to use read permissions instead of the built-in
list in init, but that broke due to the above mistaken. Since we have
already launched with these permissions as is, we must restore them.

There is a list of 'stable_properties' that vendor_init can use as
property triggers for Treble property compliance. This list came about
since init parses init scripts before all partitions are mounted and
therefore before all property context files are available, such that
init cannot use the normal SELinux mechanisms for determining if a
given property is vendor_init readable.
Currently though, we require all partitions that would contain
property context files to be mounted during first stage mount, so we
can use the normal SELinux mechanisms here, so this change deprecates
the stable_properties list and moves init to use SELinux to determine
if a property can be a trigger.

Init is special.
It starts early and does not pick up the Android ASAN options provided
on the environment. Therefore we pull in /system/asan.options in
explicitly if it exists. We provide sane defaults that will allow the
