Allows ActivityManager to use the top-app cpuset to grant the currently
focused app exclusive access to a CPU core.

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.

The Linux kernel implicitly expects /dev/fd to symlink to /proc/self/fd.
This change fixes the exec/execveat.c kernel selftest.

Mix the contents of /proc/cmdline and /default.prop
into /dev/urandom. /proc/cmdline often contains
androidboot.serialno, a device-specific unique
identifier. Similarly, /default.prop contains the
build fingerprint and timestamp, which vary between
device families.

SurfaceFlinger needs some of its threads in the system-background cpuset
and some of its threads (the binder pool) outside of the
system-background cpuset in order to improve UI perf/power
consumption. Remove surfaceflinger from the system-background cpuset in
init.rc and allow a thread to place itself in the system-background
cpuset given enough permissions.

Changes to the way FBE works to support lifecycles mean that these
commands aren't needed any more.

Core system directories should be created here in init.rc instead
of making installd do the creation.

Creation of /data/misc/vold was first introduced by commit 25775e8. It
then got reverted, probably inadvertently, by:
commit 2e24bcfdce
Author: Paul Lawrence <paullawrence@google.com>
Date: Fri May 22 18:31:55 2015 +0000
Revert "Set up crypto for user directories in init."
This folder is required by vold. In its absence, if one tries to format
an SD card as internal storage, an error will occur, with the following
message printed to logcat:
01-08 06:31:48.389 1002 1069 E vold : Failed to persist key
Restoring /data/misc/vold fixes this bug.
This fix has been verified on the emulator, which currently does not
allow its virtual SD card to be adopted, but another CL will be uploaded
to enable that.

If /sys/kernel/debug is present, make sure it has all the appropriate
SELinux labels.
Labeling of /sys/kernel/debug depends on kernel support
added in commit https://android-review.googlesource.com/122130
This patch depends on an external/sepolicy change with the
same Change-Id as this patch.

update_verifier verifies the updated partitions and marks the current
slot as having booted successfully. It needs to be triggered prior to
the start of the framework, otherwise it won't be able to fall back to
the old system without a data wipe.

This service is an enhanced version of bugreport that provides a better
user interface (like displaying progress and allowing user to enter
details).
It will be typically triggered by the 'Take Bug Report' UI, which will
now offer the option for the traditional or enhanced options (services
'bugreport' and 'bugreportplus' respectively).
