The update_engine daemon from Brillo is expected to be used also in
Android so move its selinux policy to AOSP.

Put update_engine in the whitelist (currently only has the recovery
there) allowing it to bypass the notallow for writing to partititions
labeled as system_block_device.

Also introduce the misc_block_device dev_type as update_engine in some
configurations may need to read/write the misc partition. Start
migrating uncrypt to use this instead of overly broad
block_device:blk_file access.

Bug: 23186405
Test: Manually tested with Brillo build.

vold hasn't use the generic "block_device" label since
commit 273d7ea4 (Sept 2014), and
the auditallow statement in vold hasn't triggered since that time.

Remove the rule which allows vold access to the generic block_device
label, and remove the vold exception.

Thanks to jorgelo for reminding me about this.

When service_contexts fails to build, the file is deleted
leaving only the error message for debugging. Build
service_contexts and general variant as a temporary
intermediate before running checkfc.

So add audit_read permission to capability2.

  Remove mediaserver sysfs write permissions.

* commit '3746a0ae':
  file_contexts: don't delete intermediate on failure

Currently, if an error is detected in a file_contexts
file, the intermediate file_context.tmp file is removed,
thus making debugging of build issues problematic.

Instead, employ checkfc tool during the compilation recipe
so the m4 concatenated intermediate is preserved on
failure.

Mediaserver no longer appears, and maybe never did, need write
permission to sysfs files.
commit: 1de9c492 added auditing to
make sure this is the case, and such access has not been observed.
Remove the permissions and the associated auditallow rule to further
confine the mediaserver sandbox.

Change-Id: I0c17b4e36a14afd24763343c09eaca650ea4cefd

adbd needs to kill spawned subprocesses if the client terminates
the connection. SIGHUP will be used for this purpose, which
requires the process:signal permission.
