A new directory is created in user data partition that contains preloaded

The new directory is writable/deletable by system server. It can only be

* changes:
  Sepolicy: Allow debuggerd to dump backtraces of Bluetooth
  Sepolicy: Refactor long lines for debuggerd backtraces

Since kernel 4.1 ftrace is supported as a new separate filesystem. It
gets automatically mounted by the kernel under the old path
/sys/kernel/debug/tracing. Because it lives now on a separate device
some sepolicy rules need to be updated. This patch is doing that. Most
of the rules are created based on a conversation happened on the SELinux
Android mailing list:

http://comments.gmane.org/gmane.comp.security.seandroid/2799



Note, that this also needs 3a343a1 from the 4.4 branch in kernel/common.
Also note that when tracefs is auto mounted by the kernel, the kernel
does not use the "mode" parameter specified to mount debugfs for
tracefs. So an extra line like

   chmod 0755 /sys/kernel/debug/tracing

is necessary in init.${ro.hardware}.rc after debugfs was mounted.

untrusted_app lost the ability to read files labeled as sysfs to prevent
information leakage, but this is trivially bypassable by spawning an
isolated app, since this was not taken away from isolated app.
Privileges should not be gained by launching an isolated app, and this
one directly defeats that hardeneing. Remove this access.

This policy takes effect only when building with
SANITIZE_TARGET=address and allows the Zygote to load libraries from
/data. That's where ASan-instrumented copies of system libraries are
located. 32-bit library directories have been added a while back;
this CL extends the same policy to 64-bit directories.

There is a race in ueventd's coldboot procedure that permits creation
of device block nodes before platform devices are registered. In this case
the device node links used to compute the SELinux context are not known
and the node is created under the generic context: u:object_r:block_device:s0.

Ueventd has been patched to relabel the nodes on subsequent add events but
it needs permissions to be allowed to do it.

camera_device was previously removed in AOSP commit: b7aace2d
"camera_device: remove type and add typealias" because the
same domains required access to both without exception, meaning
there was no benefit to distinguishing between the two. However,
with the split up of mediaserver this is no longer the case and
distinguishing between the camera and video  provides a legitimate
security benefit. For example, the mediacodec domain requires access
to the video_device for access to hardware accelerated codecs but does
not require access to the camera.

The boot_control HAL is library loaded by our daemons (like
update_engine and update_verifier) that interacts with the bootloader.
The actual implementation of this library is provided by the vendor and
its runtime permissions are tied to this implementation which varies a
lot based on how the bootloader and the partitions it uses are
structured.

This patch moves these permissions to an attribute so the attribute can
be expanded on each device without the need to repeat that on each one
of our daemons using the boot_control HAL.

Specifically, backup of wallpaper imagery needs to use hard links to
achieve "real file" access to the large imagery files without rewriting
the contents all the time just to stage for backup.  They can't be
symlinks because the underlying backup mechanisms refuse to act on
symbolic links for other security reasons.

Restrict the ability of the shell to set the log.*
properties. Namely: only allow the shell to set
such properities on eng and userdebug builds.

The shell (and other domains) can continue to
read log.* properties on all builds.

While there: harmonize permissions for log.* and
persist.log.tag. Doing so introduces two changes:
- log.* is now writable from from |system_app|. This
  mirrors the behavior of persist.log.tag, which is
  writable to support "Developer options" ->
  "Logger buffer sizes" -> "Off".
  (Since this option is visible on user builds, the
  permission is enabled for all builds.)
- persist.log.tag can now be set from |shell| on
  userdebug_or_eng().
