This makes the build system, for TREBLE devices only, place
plat_property_contexts under /system/etc/selinux and
nonplat_property_contexts under /vendor/etc/selinux. For other devices
these files are placed under /, same as before.
This change was previously reverted because it affected the location
of property_contexts in recovery. Now that we have separate tagets for
recovery (see ec78c377c0), this change
no longer affects is recovery.
Test: *_property_contexts in correct locations when
PRODUCT_FULL_TREBLE is set to true and when it is set to false.

This ensures that SELinux policy artifact needed by recovery at
runtime have targets in this build script. This is to make
recoveryimage/bootimage targets depend on these artifacts explicitly,
which reduces the element of surprise. Moreover, this enables us to
move non-recovery artifacts around without affecting recovery
artifacts.
Test: Clean build, flash, device boots just fine, no new denials.
Reboot to recovery, recovery boots just fine, no denials.
This was tested on bullhead (non A/B device) and sailfish (A/B

Recovery should always use monolithic policy. Thus, we don't need
split policy files *.recovery.cil. This commit removes these targets
and rolls up the relevant parts of the targets into
"sepolicy.recovery" which is the target which produces monolithic
policy for recovery.
Test: make clean && make sepolicy.recovery, then confirm that
repolicy.recovery is identical to the one produced prior to this
change.
Test: Clean build, flash, device boots up fine, no new denials. Device
also boots into recovery just fine, no denials.

This adds build targets for outputing precompiled kernel policy usable
on devices with policy split between system and vendor partitions. On
such devices, precompiled policy must reside on the vendor partition.
Because such devices support updating these partitions independently
of each other, the precompiled policy must reference the system
partition's policy against which it was compiled. This enables init to
establish whether the precompiled policy is valid for the current
combination of system and vendor partitions.
The referencing is performed by both the system and vendor partitions
including the SHA-256 digest of the system partition's policy
(plat_sepolicy.cil). Only the when the digest is the same on both
partitions can the precompiled policy be used.
Test: plat_sepolicy.cil.sha256 contains exactly the hex form of the
SHA-256 digest of plat_sepolicy.cil
Test: plat_sepolicy.cil.sha256 is identical
precompiled_sepolicy.plat.sha256.

On devices without an actual vendor image, /vendor is a symlink to
/system/vendor. When loading a library from this symlinked vendor,
the linker uses resolve_paths() resulting in an lstat(). This
generates an selinux denial. Allow this lstat() so that paths can
be resolved on devices without a real vendor image.

This moves the CIL files comprising the split sepolicy to the
directories/partitions based on whether the file is part of
platform/system or non-platform/vendor. In particular:
* plat_sepolicy.cil is moved to /system/etc/selinux,
* nonplat_sepolicy.cil is moved to /vendor/etc/selinux, and
* mapping_sepolicy.cil is moved to /vendor/etc/selinux.
Test: Device boots, no additional denials. The test is performed both
for a device without the CIL files and with the three CIL files.

This starts with the reduction in the number of services that
ephemeral apps can access. Prior to this commit, ephemeral apps were
permitted to access most of the service_manager services accessible
by conventional apps. This commit reduces this set by removing access
from ephemeral apps to:
* gatekeeper_service,
* sec_key_att_app_id_provider_service,
* wallpaper_service,
* wifiaware_service,
* wifip2p_service,
* wifi_service.
