- registers a service implementing the camera HAL
- registers a service to reveive communicate with virtual cameras via
system_server

This CL adds a new cameraservice type to allow vendor clients of
cameraservice to query and find the stable cameraservice
implementation.

instance.

system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.
Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.
Test: Device boots and no obvious problems.

If a UID is idle (being in the background for more than
cartain amount of time) it should not be able to use the
camera. If the UID becomes idle we generate an eror and
close the cameras for this UID. If an app in an idle UID
tries to use the camera we immediately generate an error.
Since apps already should handle these errors it is safe
to apply this policy to all apps to protect user privacy.

This adds fine-grained policy about who can register and find which
HwBinder services in hwservicemanager.
Test: Play movie in Netflix and Google Play Movies
Test: Play video in YouTube app and YouTube web page
Test: In Google Camera app, take photo (HDR+ and conventional),
record video (slow motion and normal), and check that photos
look fine and videos play back with sound.
Test: Cast screen to a Google Cast device
Test: Get location fix in Google Maps
Test: Make and receive a phone call, check that sound works both ways
and that disconnecting the call frome either end works fine.
Test: Run RsHelloCompute RenderScript demo app
Test: Run fast subset of media CTS tests:
make and install CtsMediaTestCases.apk
adb shell am instrument -e size small \
-w 'android.media.cts/android.support.test.runner.AndroidJUnitRunner'
Test: Play music using Google Play music
Test: Adjust screen brightness via the slider in Quick Settings
Test: adb bugreport
Test: Enroll in fingerprint screen unlock, unlock screen using
fingerprint
Test: Apply OTA update:
Make some visible change, e.g., rename Settings app.
make otatools && \
make dist
Ensure device has network connectivity
ota_call.py -s <serial here> --file out/dist/sailfish-ota-*.zip
Confirm the change is now live on the device

Since hal_graphics_composer_default is now no longer
a member of binderservicedomain, these domains would
no longer be able to use filedescriptors from it.

This adds restrictions on which domains can register this HwBinder
service with hwservicemanager and which domains can obtain tokens for
this service from hwservicemanager.
Test: Use Google Camera app to take HDR+ photo, conventional photo,
record video with sound, record slow motion video with sound.
Check that the photos display correctly and that videos play
back fine and with sound. Check that there are no SELinux
denials to do with camera.

This is a follow-up to 9339168688
which added both
hal_client_domain(cameraserver, hal_graphics_allocator) and
binder_call(cameraserver, hal_graphics_allocator). The latter
binder_call rule is no longer needed because it is automatically
granted by virtue of cameraserver being marked as a client of
Graphics Allocator HAL --
see 49274721b3.
Test: Take a photo (both HDR and conventional) using Google Camera
Test: Record video using Google Camera
Test: Record slow motion video using Google Camera
Test: No denials to do with cameraserver and hal_graphics_allocator*

This switches Camera HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Camera HAL.
Domains which are clients of Camera HAL, such as cameraserver domain,
are granted rules targeting hal_camera only when the Camera HAL runs
in passthrough mode (i.e., inside the client's process). When the HAL
runs in binderized mode (i.e., in another process/domain, with clients
talking to the HAL over HwBinder IPC), rules targeting hal_camera are
not granted to client domains.
Domains which offer a binderized implementation of Camera HAL, such
as hal_camera_default domain, are always granted rules targeting
hal_camera.
Test: Take non-HDR photo using Google Camera app

Introduce the add_service() macro which wraps up add/find
permissions for the source domain with a neverallow preventing
others from adding it. Only a particular domain should
add a particular service.
Use the add_service() macro to automatically add a neverallow
that prevents other domains from adding the service.
mediadrmserver was adding services labeled mediaserver_service.
Drop the add permission as it should just need the find
permission.
Additionally, the macro adds the { add find } permission which
causes some existing neverallow's to assert. Adjust those
neverallow's so "self" can always find.
Test: compile and run on hikey and emulator. No new denials were
found, and all services, where applicable, seem to be running OK.

- Allow cameraservice to talk to hwbinder, hwservicemanager
- Allow hal_camera to talk to the same interfaces as cameraservice
Test: Compiles, confirmed that cameraservice can call hwservicemanager

Divide policy into public and private components. This is the first
step in splitting the policy creation for platform and non-platform
policies. The policy in the public directory will be exported for use
in non-platform policy creation. Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.
Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal. For now, almost all types and
avrules are left in public.
Test: Tested by building policy and running on device.
