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.

If / is not write-able and system.img contains system/vendor, symlink
for `/vendor/ -> /system/vendor/` that is otherwise done in init.rc
should be done at build time.

Folders in the root directory are now created during the build,
as we may be building without a ramdisk, and when we do that,
the root directory will be read-only. With those changes,
these mkdirs will never need to run.

Move foreground tasks to /sys/fs/cgroup/stune/boost/tasks (boosted
weight in EAS scheduler). Move background tasks to
/sys/fs/cgroup/stune/tasks (default weight). For services started
with init, set "foreground" services to boosted.

system.img may contain the root directory as well. In that case, we
need to create some folders init.rc would during the build.

Add the following mount options to the /proc filesystem:
hidepid=2,gid=3009
This change blocks /proc access unless you're in group 3009
(aka AID_READPROC).
Please see
https://github.com/torvalds/linux/blob/master/Documentation/filesystems/proc.txt
for documentation on the hidepid option.
hidepid=2 is preferred over hidepid=1 since it leaks less information
and doesn't generate SELinux ptrace denials when trying to access
/proc without being in the proper group.
Add AID_READPROC to processes which need to access /proc entries for
other UIDs.

Building without ramdisk requires a way to specify board specific
directoryies and symlinks in the root directory at build time.

(cherry picked from commit d7549c9a65cad886f672af41f5fca6f0bd0c12fa)
3.18 has a warning in dmesg that appears when the parent cpuset's cpus
and mems are changed to something other than what the child has. Reorder
init.rc to prevent this warning from appearing.

Don't allow the accidental triggering of sysrq functionality
from the keyboard. The only expected use of sysrq functionality
is via /proc/sysrq-trigger
Please see https://www.kernel.org/doc/Documentation/sysrq.txt for
additional information on /proc/sys/kernel/sysrq

Ensure that /data/misc/update_engine exists since it will be referenced
by selinux policy.
