Current kills message prints min_score_adj marked as "oom_adj" which
is confusing. This change marks it as "min_oom_adj" to be more clear.

system_server needs to register with lmkd, however it has no memory
cgroup under /dev/memcg/apps. This change detects if the process being
registered is system_server and suppresses the error message when
/dev/memcg/apps/uid_%d/pid_%d/memory.soft_limit_in_bytes file can't
be accessed.

Occasionally processes are killed or crash while lmkd is trying to access
their oom_score_adj file. This is not necessarily an erroneous condition
and therefore should not be reported as an error. Demoting error to a
warning with a detailed message.

Allow for a daemon to write to last kmsg to propagate a detailed
subreason to kernel_panic,sysrq actions. A minor refactor moves
common code into a helper function getSubreason for retrieval and
bit error correction operations.
A sysrq crash generally produces a kernel-provided message:
SysRq : Trigger a crash
which is used to generate a canonical boot reason kernel_panic,sysrq.
A user daemon could write to /dev/kmsg just prior to the sysrq with
SysRq : Trigger a crash : '<subreason>'
to change the canonical boot reason to kernel_panic,sysrq,<subreason>.
Administration added pending kBootReasonMap entries present in TRON.
Test: manual echo into /dev/kmsg and /proc/sysrq-trigger and check

Hopefully the quick property test is first, setting the stage for
ignoring future failures. This solves a problem with multiple
test failures directly attributed to a CTS compliance issue
with the bootloader's boot reason. One test fails, the remainder
get a pass on this one issue.

There has been no section in the linker config file for the binaries
under /postinstall. As a result, the binaries were run with the legacy
default config where /vendor/lib and /odm/lib are added to the search
paths. This is causing selinux denials as the binaries for OTA are not
allowed to access /vendor/lib or /odm/lib, but the dynamic linker calls
realpath(3) on the paths to canonicalize them.
Fixing the issue by letting /postinstall/* binaries to run with a
dedicated linker namespace config, where /vendor/lib and /odm/lib are
not added to the search paths. Not having the paths is okay because
he OTA binaries should not have dependency to the libs there.

For all known cases, if usb is present in the bootloader reason,
then it is actually reporting a cold,charger canonical boot reason.
This signifies that the device was powered down, and was woken
up by the charger being connected.
For all known cases, if rtc is present in the bootloader reason,
then it is actually reporting a cold,rtc canonical boot reason.
This signifies that the device was powered down, and was woken
