When vold mounts things in /mnt/secure/staging, it expects to MS_MOVE
those mountpoints when vetting is finished. However, the kernel
doesn't allow MS_MOVE when the source is shared to child namespaces.
To work around this, create a tmpfs at /mnt/secure and mark it as
private (not shared). Verified that vold can now successfully move
from the staging area.

Define /storage as top-level concept, so that we enforce permissions
uniformly. Moves external storage paths from headers to per-device
environment variables. Added missing mount flags, and we no longer
have adb-specific external storage.

Also remove mount() from adb, since it can come online long before
data partition is ready. Set EXTERNAL_STORAGE environment variable
to point to owner for backwards compatibility.

Remount rootfs as recursively shared, so that mount changes are
propagated into child namespaces. Mount external storage for access
from adb.
Clean multi-user dependencies for use in Dalvik. Also define
external storage paths.

To support runtime policy management, add support for reloading
policy from /data/system. This can be triggered by setting the
selinux.loadpolicy property to 1, whether from init.rc after
mounting /data or from the system_server (e.g. upon invocation of
a new device admin API for provisioning policy). ueventd and
installd are restarted upon policy reloads to pick up the new
policy configurations relevant to their operation.

Set the security context for the init process.
Restore the security contexts of /cache and /data in case they were reset.
Specify the security context for services launched from the rootfs since
we cannot label their executables.
If on the emulator, set a policy boolean and restore the context of
/sys/qemu_trace to allow accesses not normally permitted on a device.

This change adds init.rc steps to:
* allow kernel tracing to be enabled via adb
* allow a limited set of kernel trace events to be enabled via adb
* allow the kernel trace to be read via adb
* allow all users to write to the kernel trace from userland

With this change, the audio rr/fifo threads will just run in
the fg cgroup.
Also, the RR budget for the apps fg/bg threads has been bumped
to 80%. Ideally, the bg budget would be much smaller but there
are legacy libraries that seem to be very sensitive to this so
for now keep it at this value.
