All SELinux domains are already granted the ability to read the
filenames in /proc, so it's unnecessary to add it to storaged.te.

  $ grep "proc:dir r_dir_perms" public/domain.te
  allow domain proc:dir r_dir_perms;

Remove redundant rule.

Test: policy compiles.

This leaves only the existence of system_app domain as public API.
All other rules are implementation details of this domain's policy and
are thus now private.

      disappearance of all allow rules from system_app_current

Commit fee49159 introduced the net_radio_prop and system_radio_prop
properties, and added allow rules for backwards compatibility. In
addition, auditallow rules were added to see if the allow rules were
necessary.

The auditallow rules for radio net_radio_prop are triggering, so it's
clear these properties are being set by the radio process. Drop the
auditallow statement.

Test: policy compiles.

/proc/tty/drivers is read by applications to figure out if they are
running in an emulated environment. Specifically, they look for the
string "goldfish" within that file.

Arguably this is not an Android API, and really shouldn't be exposed to
applications, but:

1) A largish number of applications break if they can't read this file;
2) The information here isn't particularly sensitive

While we could spend a bunch of time trying to get applications fixed,
there are bigger fish to fry. It's not worth the battle.

Test: "ls -laZ /proc/tty/drivers" is labeled properly.

This removes access to Bluetooth system properties from arbitrary
SELinux domains. Access remains granted to init, bluetooth, and
system_app domains. neverallow rules / CTS enforce that access is not
granted to Zygote and processes spawned from Zygote expcept for
system_app and bluetooth.

The reason is that some of these properties may leak persistent
identifiers not resettable by the user.

Test: Bluetooth pairing and data transfer works
