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.

On eng and userdebug builds (only), allow system server
to change the value of log.tag.WifiHAL. WifiStateMachine
will set this property to 'D' by default. If/when a user
enables "Developer options -> Enable Wi-Fi Verbose Logging",
WifiStateMachine change log.tag.WifiHAL to 'V'.

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().

Add a neverallow rule (compile time assertion + CTS test) that
isolated_apps and untrusted_apps can't do anything else but append
to /data/anr/traces.txt. In particular, assert that they can't
read from the file, or overwrite other data which may already be
in the file.

Allow adbd and app domains to read the symlink at /mnt/sdcard.
This symlink was suppose to have been removed in the Gingerbread
time frame, but lives on.

Read access for this symlink was removed from adbd and the shell user in
8ca19368, and from untrusted_app in
cbf7ba18.

Addresses the following denials:

  avc: denied { read } for name="sdcard" dev="tmpfs" ino=9486 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:tmpfs:s0 tclass=lnk_file permissive=0

postinstall_file was an exec_type so it could be an entrypoint for the
domain_auto_trans from update_engine domain to postinstall domain. This
patch removes the exec_type from postinstall_file and exempts it from
the neverallow rule to become an entrypoint.

TEST=postinstall_example still runs as the "postinstall" domain on edison-eng.
