This is a necessary first step to finalizing the SELinux policy build
process.  The mapping_sepolicy.cil file is required to provide backward
compatibility with the indicated vendor-targeted version.

This still needs to be extended to provide N mapping files and corresponding
SHA256 outputs, one for each of the N previous platform versions with which
we're backward-compatible.

Bug: 36783775
Test: boot device with matching sha256 and non-matching and verify that
device boots and uses either precompiled or compiled policy as needed. Also
verify that mapping_sepolicy.cil has moved.

sepolicy-analyze allows users to see all types that have a given
attribute, but not the reverse case: all attributes of a given type.
Add a '--reverse' option which enables this, but keeps the previous
interface.

Usage: sepolicy-analyze sepolicy attribute -r init

logcatd is the same as logcat, except that the -L flag, if supplied,
runs once, then the command re-runs itself without the -L flag with
the same argument set.  By introducing a logcatd daemon executable
we can solve the problem of the longish reads from pstore that
sometimes occur when the system is excessively busy spinning in a
foreground task starving this daemon as we absorb the delay in
an init service, rather than in an init exec.  This would not have
been efficiently possible without the introduction of liblogcat.

The CL splits /vendor labeling from /system. Which was allowing all
processes read, execute access to /vendor.

Following directories will remain world readable
 /vendor/etc
 /vendor/lib(64)/hw/

Following are currently world readable but their scope
will be minimized to platform processes that require access
 /vendor/app
 /vendor/framework/
 /vendor/overlay

Files labelled with 'same_process_hal_file' are allowed to be
read + executed from by the world. This is for Same process HALs and
their dependencies.

Wifi Keystore HAL is a HwBinder service (currently offered by keystore
daemon) which is used by Wifi Supplicant HAL. This commit thus
switches the SELinux policy of Wifi Keystore HAL to the approach used
for non-HAL HwBinder services.

The basic idea is simimilar to how we express Binder services in the
policy, with two tweaks: (1) we don't have 'hwservicemanager find' and
thus there's no add_hwservice macro, and (2) we need loosen the
coupling between core and vendor components. For example, it should be
possible to move a HwBinder service offered by a core component into
another core component, without having to update the SELinux policy of
the vendor image. We thus annotate all components offering HwBinder
service x across the core-vendor boundary with x_server, which enables
the policy of clients to contain rules of the form:
binder_call(mydomain, x_server), and, if the service uses IPC
callbacks, also binder_call(x_server, mydomain).

Currently update_verifier only verifies the blocks when dm-verity is in
'enforcing' mode; and dm-verity will reboot the device upon detection of
errors. However, sometimes the verity mode is not guaranteed to be
correct. When mode is 'eio' for example, dm-verity will not trigger
a reboot but rather fail the read. So update_verifier need to take the
responsibility to reboot the device. Otherwise the device will continue
to boot without setting the flag "isSlotMarkedSuccessful".
