1) Don't use the generic "system_data_file" for the files in /data/nativetest.
Rather, ensure it has it's own special label. This allows us to distinguish
these files from other files in SELinux policy.

2) Allow the shell user to execute files from /data/nativetest, on
userdebug or eng builds only.

3) Add a neverallow rule (compile time assertion + CTS test) that nobody
is allowed to execute these files on user builds, and only the shell user
is allowed to execute these files on userdebug/eng builds.

1) Don't allow any SELinux domain to attempt to perform a text
relocation on a file from the /system partition. It's not supported
and should never be attempted.

2) Completely block any non-app SELinux domains from using text
relocations, regardless of the source.

Occasionally, files get labeled with the domain type rather
than the executable file type. This can work if the author
uses domain_auto_trans() versus init_daemon_domain(). This
will cause a lot of issues and is typically not what the
author intended.

Another case where exec on domain type might occur, is if
someone attempts to execute a /proc/pid file, this also
does not make sense.

To prevent this, we add a neverallow.

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.

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.
