We are making a change to uevent_open_socket() in libcutils related to
setting the receive buffer size of netlink uevent sockets.

After setting SO_RCVBUF, we immediately read it back using getsockopt()
to verify that the setsockopt() call was effective. Only if it was not
effective, we call setsockopt() with SO_RCVBUFFORCE.

getsockopt() previously caused SELinux denials like the following:

Currently, when an APEX is staged, apexd moves the file from
/data/app/vmdl*.tmp directory to /data/apex. However, the original file
is labeled with apk_tmp_file and is not readable from apexd.

We plan to resolve this issue by moving the file content via file
descriptor in between the package manager and apexd.

However, until the plan is implemented, temporarily allow apexd to
relabel the file to apex_data_file that is readable to it. This unblocks
the end-to-end test for APEX.

Test: adb install --apex system/apex/apexd/apexd_testdata/test.apex

Move rules / neverallow assertions from public to private policy. This
change, by itself, is a no-op, but will make future patches easier to
read. The only downside of this change is that it will make git blame
less effective.

Motivation: When rules are placed into the public directory, they cannot
reference a private type. A future change will modify these rules to
reference a private type.

NIAP certification requires that all cryptographic functions
undergo a self-test during startup to demonstrate correct
operation. init now performs this check during startup.

The self-test is forked from init. For the child process
to be able to request a reboot it needs permissions to
set the sys.powerctl property.

The SELinux policy language supports an expandattribute statement.
Similar to the C "inline" declaration, this expands the permissions
associated with types, instead of using the attribute directly. Please
see
https://android.googlesource.com/platform/external/selinux/+/1089665e31a647a5f0ba2eabe8ac6232b384bed9
for more detail on this language option.

Expansion of attributes causes consistency problems with CTS. If a
neverallow rule exists which refers to an expanded attribute, the CTS
neverallow test will fail, because the policy does not have the
attribute embedded in it. Examples:

  * b/119783042 (fixed in 536d3413)
  * b/67296580 (fixed in 6f7e8609)
  * b/63809360 (fixed in 89f215e6)
  etc...

Instead of waiting for the CTS test to fail, modify the Android.mk file
so that we do checks similar to CTS. This allows us to fail at compile
time instead of waiting for a CTS bug. For example, for b/119783042,
instead of the compile succeeding, it will now fail with the following
error message:
