All HALs which are represented by hal_* attributes in SELinux policy
are required to run in binderized mode on Treble devices. This commit
thus makes the SELinux policy for Treble devices no longer associate
domains in hal_x_client with hal_x attribute, which is what was
granting domains hosting clients of hal_x the rules needed to run this
HAL in-process. The result is that core components have now less

CTS includes general_sepolicy.conf built from this project. CTS then
tests this file's neverallow rules against the policy of the device
under test. Prior to this commit, neverallow rules which must be
enforced only for Treble devices we not included into
general_sepolicy.conf. As a result, these rules were not enforced for
Treble devices.

This commit fixes the issue as follows. Because CTS includes only one
policy, the policy now contains also the rules which are only for
Treble devices. To enable CTS to distinguish rules needed for all
devices from rules needed only on Treble devices, the latter rules are
contained in sections delimited with BEGIN_TREBLE_ONLY and
END_TREBLE_ONLY comments.

This commit also removes the unnecessary sepolicy.general target. This
target is not used anywhere and is causing trouble because it is
verifying neverallows of the policy meant to be used by CTS. This
policy can no longer be verified with checkpolicy without
conditionally including or excluding Treble-only neverallows.

This change associates all domains which are clients of Allocator HAL
with hal_allocator_client and the, required for all HAL client
domains, halclientdomain.

This enables this commit to remove the now unnecessary hwallocator_use
macro because its binder_call(..., hal_allocator_server) is covered by
binder_call(hal_allocator_client, hal_allocator_server) added in this
commit.

Unfortunately apps, except isolated app, are clients of Allocator HAL
as well. This makes it hard to use the hal_client_domain(...,
hal_allocator) macro because it translates into "typeattribute" which
currently does not support being provided with a set of types, such as
{ appdomain -isolated_app }. As a workaround, hopefully until
typeattribute is improved, this commit expresses the necessary
association operation in CIL. private/technical_debt.cil introduced by
this commit is appended into the platform policy CIL file, thus
ensuring that the hack has effect on the final monolithic policy.

P. S. This change also removes Allocator HAL access from isolated_app.
Isolated app shouldn't have access to this HAL anyway.

On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor
apps) are not permitted to use Binder. This commit thus:
* groups non-vendor domains using the new "coredomain" attribute,
* adds neverallow rules restricting Binder use to coredomain and
  appdomain only, and
* temporarily exempts the domains which are currently violating this
  rule from this restriction. These domains are grouped using the new
  "binder_in_vendor_violators" attribute. The attribute is needed
  because the types corresponding to violators are not exposed to the
  public policy where the neverallow rules are.

This switches Allocator HAL policy to the design which enables us to
identify all SELinux domains which host HALs and all domains which are
clients of HALs.

Allocator HAL is special in the sense that it's assumed to be always
binderized. As a result, rules in Camera HAL target hal_allocator_server
rather than hal_allocator (which would be the server and any client, if
the Allocator HAL runs in passthrough mode).

This starts the switch for HAL policy to the approach where:
* domains which are clients of Foo HAL are associated with
  hal_foo_client attribute,
* domains which offer the Foo HAL service over HwBinder are
  associated with hal_foo_server attribute,
* policy needed by the implementation of Foo HAL service is written
  against the hal_foo attribute. This policy is granted to domains
  which offer the Foo HAL service over HwBinder and, if Foo HAL runs
  in the so-called passthrough mode (inside the process of each
  client), also granted to all domains which are clients of Foo HAL.
  hal_foo is there to avoid duplicating the rules for hal_foo_client
  and hal_foo_server to cover the passthrough/in-process Foo HAL and
  binderized/out-of-process Foo HAL cases.

A benefit of associating all domains which are clients of Foo HAL with
hal_foo (when Foo HAL is in passthrough mode) is that this removes the
need for device-specific policy to be able to reference these domains
directly (in order to add device-specific allow rules). Instead,
device-specific policy only needs to reference hal_foo and should no
longer need to care which particular domains on the device are clients
of Foo HAL. This can be seen in simplification of the rules for
audioserver domain which is a client of Audio HAL whose policy is
being restructured in this commit.

This commit uses Audio HAL as an example to illustrate the approach.
Once this commit lands, other HALs will also be switched to this
approach.

Motivation:
Provide the ability to phase in new security policies by
applying them to apps with a minimum targetSdkVersion.

Place untrusted apps with targetSdkVersion<=25 into the
untrustd_app_25 domain. Apps with targetSdkVersion>=26 are placed
into the untrusted_app domain. Common rules are included in the
untrusted_app_all attribute. Apps with a more recent targetSdkVersion
are granted fewer permissions.

Test: Marlin builds and boots. Apps targeting targetSdkVersion<=25
run in untrusted_app_25 domain. Apps targeting the current development
build >=26 run in the untrusted_app domain with fewer permissions. No
