To generate compat files, we need the following files.
- base_plat_sepolicy: to get all types
- base_plat_pub_policy.cil: to get public types
- {ver}_plat_sepolicy: to get old types
This creates a new dist goal, base-sepolicy-files-for-mapping, to
conveniently generate and gather desired files under out/dist.

Types defined in system_ext/public or product/public
can be referenced by vendor side so it is important
to make sure functionality is not broken across version
bumps. So we are adding the treble sepolicy test cases
for system_ext and product sepolicy.

This is the flag for when sepolicy is split. Also removed other

entirely instead.

Bug: http://b/135139675
Coverage files are written to /data/misc/trace (governed by the
method_trace_data_file selinux type). Allow all domains to access
(create directories, access files) this directory when native coverage
is enabled (by setting NATIVE_COVERAGE to true) in an userdebug or eng
build.
Also relax neverallow constraints to allow access to
method_trace_data_file for native coverage builds.
Test: Build 32-bit cuttlefish with coverage:
m NATIVE_COVERAGE=true COVERAGE_PATHS="*"
and verify that there are no selinux denials in kernel log and
logcat.

*_context_test / sepolicy_tests / treble_sepolicy_tests_* /
sepolicy_freeze_test files are installed on /system/etc.
By being FAKE modules, test files are not installed on target.
Additionally, we need to set up dependency from droidcore to
selinux_policy to make tests run on normal builds (m).

Emulator device can not be considered a full treble device even though
it has PRODUCT_SHIPPING_API_LEVEL = 28. This is prevents us from merging
neverallow rules that implement Treble requirements (aosp/798433). As a
temporary workaround, disable the checks on that variable.

New maintenance scheme for mapping files:
Say, V is the current SELinux platform version, then at any point in time we
only maintain (V->V-1) mapping. (V->V-n) map is constructed from top (V->V-n+1)
and bottom (V-n+1->V-n) without changes to previously maintained mapping files.
Caveats:
- 26.0.cil doesn't technically represent 27.0->26.0 map, but rather
current->26.0. We'll fully migrate to the scheme with future releases.

Test: adding new public type only requires changing the latest compat map

Private types are not visible to vendor/odm policy, so we don't need mapping
entries for them.
We build platform-only public policy .cil file and give it as input to
treble_sepolicy_tests. Using this public policy the test can now figure out if
the newly added type in public or private.
Bug: 116344577
Test: adding public type triggers mapping test failure, adding private type does
not.

(for the build-time tests)
treble_sepolicy_tests applies tests to the SEPolicy for devices which
implement the SEPolicy split introduced in Android O. For devices which
turn this on and also implement all of the other requirements which
together compose PRODUCT_FULL_TREBLE, these tests help ensure that the
backwards compatibility which this feature adds is possible.
When this test was originally written, devices which specified
PRODUCT_FULL_TREBLE_OVERRIDE were only those devices with a
PRODUCT_SHIPPING_API_LEVEL of < 26. This allowed them to update to use
these features but maintain some legacy behaviors. For these devices,
to achieve the same backwards compatibility guarantees, much
other/extra work would have to be done (if it is possible at all).
Since that time, a new category of devices take advantage of
PRODUCT_FULL_TREBLE_OVERRIDE. These devices must either not define a
PRODUCT_SHIPPING_API_LEVEL or they apply this flag even though it is
not required to be applied. For these cases, the full test suite not
being run has caused problems because these failures aren't discoverred
until later (when compliance tests are run).

Steps taken to produce the mapping files:
1. Add prebuilts/api/28.0/[plat_pub_versioned.cil|vendor_sepolicy.cil]
from the /vendor/etc/selinux/[plat_pub_versioned.cil|vendor_sepolicy.cil]
files built on pi-dev with lunch target aosp_arm64-eng
2. Add new file private/compat/28.0/28.0.cil by doing the following:
- copy /system/etc/selinux/mapping/28.0.cil from pi-dev aosp_arm64-eng
device to private/compat/28.0/28.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 28 sepolicy.
Find all such types using treble_sepolicy_tests_28.0 test.
- for all these types figure out where to map them by looking at
27.0.[ignore.]cil files and add approprite entries to 28.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_28.0 and install 28.0.cil
mapping onto the device.

Use the user policy when running the compatibility tests.

Test: Built policy for many devices. Booted one device.

When building userdebug or eng builds, we still want to build the user
policy when checking neverallow rules so that we can catch compile
errors.
Commit c0713e86 split out a helper function but lost one instance of
using user instead of the real variant. This restores that one and
adds it to the neverallow check.
Bug: 74344625
Test: Added a rule that referred to a type defined only
in userdebug and eng and ensure we throw a compile error when building
userdebug mode.
