d9b8ef4352 Drop legacy device types.
powervr_device is obsoleted by the more general gpu_device.
akm_device and accelerometer_device are obsoleted by the more
general sensors_device.

We could also drop the file_contexts entries altogether and
take them to device-specific policy (in this case, they all
came from crespo, so that is obsolete for master).

b2547644ef Drop tegra specific label from policy.
This label was originally used for Motorola
Xoom devices. nvmap is the tegra gpu memory
manager and the various nvhost drivers are
for tegra graphics related functionality,
i.e. display serial interface, image signal
processor, or media processing stuff.

Only grouper and tilapia presently need this
policy.

af47ebb67a Label /dev/fscklogs and allow system_server access to it.
Otherwise you get denials such as:

8d688315ae Restrict access to /dev/hw_random to system_server and init.
/dev/hw_random is accessed only by init and by EntropyMixer (which
runs inside system_server). Other domains are denied access because
apps/services should be obtaining randomness from the Linux RNG.

69fbbdd54b DO NOT MERGE Split some device nodes out from device.
Some of these will get factored out into device-specific
configs later.

74ba8c8613 run-as policy fixes.
- Remove dac_read_search as it is no longer required by run-as.
- Introduce a separate type for /dev/tty so that we can allow use of own tty for
for a run-as shell without allowing access to other /dev/tty[0-9]* nodes.
- Allow sigchld notifications for death of run-as and its descendants by adbd.
- Drop redundant rules for executing shell or system commands from untrusted_app;
now covered by rules in app.te.

4c06d273bc Target the denials/policies over qtaguid file and device: 1. Relabel /proc/net/xt_qtaguid/ctrl from "qtaguid" to "qtaguid_proc"; 2. Label /dev/xt_qtaguid with "qtaguid_device"; 3. Allow mediaserver read/[write] to qtaguid_proc and qtaguid_device; 4. Allow media apps read/[write] to qtaguid_proc and qtaguid_device; 5. Allow system read/[write] to qtaguid_proc and qtaguid_device.
Actually, some of policies related to qtaguid have been there already, but
we refind existing ones and add new ones.
