Restrict access to hwservicemanager 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 Bug: 34454312 (cherry picked from commit 632bc494f199d9d85c37c1751667fe41f4b094cb) Merged-In: Iecf74000e6c68f01299667486f3c767912c076d3 Change-Id: I7a9a487beaf6f30c52ce08e04d415624da49dd31

# The goal of the mediaserver split is to place media processing code into
# restrictive sandboxes with limited responsibilities and thus limited
# permissions. Example: Audioserver is only responsible for controlling audio
# hardware and processing audio content. Cameraserver does the same for camera
# hardware/content. Etc.
#
# Media processing code is inherently risky and thus should have limited
# permissions and be isolated from the rest of the system and network.
# Lengthier explanation here:
