Extend the asan.options file to read binary-specific configuration
from files out of /system. For early services, the system image
location is important as /data may not be available when they are
started.
Add a template that turns most sanitization off. At this point in
time, it is, however, impossible to get to a zero overhead state
after the fact. The template is meant to adapt a build after the
fact, and work around issues with LOCAL_SANITIZE := never.
Add a Make variable and rule copying the template to the path and
name expected by ASAN. Add SANITIZE_LITE to automatically add a
large set of options files.

We will store OTA packages there for both A/B and non-A/B OTAs. The
directory will be accessed by GMSCore (for both), uncrypt (non-A/B),
update_engine (A/B), update_verifier (A/B) and possibly system server
(for non-A/B OTAs to clean up half-way uncrypt'd packages).

(Cherry picked from commit 2b22a66382)
This adds a system property for controlling unprivileged access to
perf_event_paranoid. It depends on adding kernel support for
perf_event_paranoid=3 based on grsecurity's PERF_HARDEN feature to
completely disable unprivileged access to perf. A minimal port of this
feature is used in the vanilla Debian kernel by default.
It hides the non-hardened value as an implementation detail, since while
it is currently 1, it will probably become 2 in the future.

In the case of adb enabled, When a usb function switch happens
e.g mtp,adb -> ptp,adb, framework will set sys.usb.config from
"mtp,adb" to "none" and stop adbd first.
At this time, the property "sys.usb.ffs.ready", which is set after
the ready of the perious start adbd, is still "1".
So , when framework goes on setting the sys.usb.config to "ptp,adb",
init.usb.configfs.rc will trigger actions to bind() f_fs without
waiting for adbd is actually ready.
This will produce some error messages:
------------
configfs-gadget ci_hdrc.0: failed to start g1: -19
init: write_file: Unable to write to '/config/usb_gadget/g1/UDC': No such device
------------
this error msg is caused by configFS start binding f_fs before adbd is ready.
Add setting the "sys.usb.ffs.ready" to "0" will help clear this error msg,
as the bind process in kernel gadget driver will wait for the set of
this property, which is the sign of adbd is ready.

libprocessgroup checks whether it can use memory
cgroups for keeping track of forked processes by
seeing whether /dev/memcg/apps is writable. However,
on systems with memory cgroups disabled, SELinux
(correctly) no longer classifies this directory as a cgroup,
and starts denying zygote access. To fix this,
first check whether /dev/memcg/apps/tasks exists to
see if the cgroup is mounted; only then check whether
we can write to the directory.

It turns out we were using the CPU accounting
cgroups for keeping track of processes that were
forked by an app without the framework's knowledge,
so we could kill all of them reliably (see b/15313911
for context).
Since we want to use memory cgroups for other purposes,
we might as well use memory cgroups for tracking forked
PIDs if they're enabled. This also gets us automatic cleanup
of empty mem cgroups.
Also, removed old mem cgroup mount point that is no
longer used, as well as cgroup release agent code that
we're not using.
