This should be obsoleted by the restorecon in
I30e4d2a1ae223a03eadee58a883c79932fff59fe .

adbd was only in enforcing for user builds. Commit
Ib33c0dd2dd6172035230514ac84fcaed2ecf44d6 allows us to move
it into enforcing for everyone. Do it.

When adbd runs as root, it transitions into the
su domain. Add the various rules to support this.
This is needed to run the adbd and shell domains in
enforcing on userdebug / eng devices without breaking
developer workflows.

adbd uses setpcap to drop capabilities from the bounding
set on user builds. See system/core commit

Will likely want to split into adbd_user.te vs adbd.te before
going enforcing to support adb root and adb remount on non-user builds.
Possibly take all common rules to an adbdcommon.te.

Confine run-as (but leave permissive for now) and add
other allow rules required for the use of run-as and ndk-gdb
functionality.

This change removes the permissive line from unconfined
domains. Unconfined domains can do (mostly) anything, so moving
these domains into enforcing should be a no-op.
The following domains were deliberately NOT changed:
1) kernel
2) init
In the future, this gives us the ability to tighten up the
rules in unconfined, and have those tightened rules actually
work.
When we're ready to tighten up the rules for these domains,
we can:
1) Remove unconfined_domain and re-add the permissive line.
2) Submit the domain in permissive but NOT unconfined.
3) Remove the permissive line
4) Wait a few days and submit the no-permissive change.
For instance, if we were ready to do this for adb, we'd identify
a list of possible rules which allow adbd to work, re-add
the permissive line, and then upload those changes to AOSP.
After sufficient testing, we'd then move adb to enforcing.
We'd repeat this for each domain until everything is enforcing
and out of unconfined.

The /adb_keys entry will only take effect if a restorecon is
applied by init.rc on a kernel that includes the rootfs labeling
support, but does no harm otherwise.
The /data/misc/adb labeling ensures correct labeling of the adb_keys
file created if the device has ro.adb.secure=1 set.
Allow adbd to read the file.

This prevents denials from being generated by the base policy.
Over time, these rules will be incrementally tightened to improve
security.

Read access to /dev/log/* is no longer restricted.
Filtering on reads is performed per-uid by the kernel logger driver.

Update policy for Android 4.2 / latest master.
Primarily this consists of changes around the bluetooth subsystem.
The zygote also needs further permissions to set up /storage/emulated.
adbd service now gets a socket under /dev/socket.
keystore uses the binder.
