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.

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.
