This switches Boot Control HAL policy to the design which enables us
to conditionally remove unnecessary rules from domains which are
clients of Boot Control HAL.
Domains which are clients of Boot Control HAL, such as update_server,
are granted rules targeting hal_bootctl only when the Boot Control HAL
runs in passthrough mode (i.e., inside the client's process). When the
HAL runs in binderized mode (i.e., in another process/domain, with
clients talking to the HAL over HwBinder IPC), rules targeting
hal_bootctl are not granted to client domains.
Domains which offer a binderized implementation of Boot Control HAL,
such as hal_bootctl_default domain, are always granted rules targeting
hal_bootctl.
P. S. This commit removes direct access to Boot Control HAL from
system_server because system_server is not a client of this HAL. This
commit also removes bootctrl_block_device type which is no longer
used. Finally, boot_control_hal attribute is removed because it is now
covered by the hal_bootctl attribute.

This switches most remaining HALs to the _client/_server approach.
To unblock efforts blocked on majority of HALs having to use this
model, this change does not remove unnecessary rules from clients of
these HALs. That work will be performed in follow-up commits. This
commit only adds allow rules and thus does not break existing
functionality.
The HALs not yet on the _client/_server model after this commit are:
* Allocator HAL, because it's non-trivial to declare all apps except
isolated apps as clients of this HAL, which they are.
* Boot HAL, because it's still on the non-attributized model and I'm
waiting for update_engine folks to answer a couple of questions
which will let me refactor the policy of this HAL.

This switches Sensors HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Sensors HAL.
Domains which are clients of Sensors HAL, such as system_server, are
granted rules targeting hal_sensors only when the Sensors HAL runs in
passthrough mode (i.e., inside the client's process). When the HAL
runs in binderized mode (i.e., in another process/domain, with clients
talking to the HAL over HwBinder IPC), rules targeting hal_sensors are
not granted to client domains.
Domains which offer a binderized implementation of Sensors HAL, such
as hal_sensors_default domain, are always granted rules targeting
hal_sensors.
P. S. This commit also removes
allow system_server sensors_device:chr_file rw_file_perms
because this is device-specific and thus not needed in device-agnostic
policy. The device-specific policy of the affected devices already has
this rule.
Test: Device boots, no new denials
Test: adb shell dumpsys sensorservice

This switches Keymaster HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Keymaster HAL.
Domains which are clients of Keymaster HAL, such as keystore and vold
domains, are granted rules targeting hal_keymaster only when the
Keymaster HAL runs in passthrough mode (i.e., inside the client's
process). When the HAL runs in binderized mode (i.e., in another
process/domain, with clients talking to the HAL over HwBinder IPC),
rules targeting hal_keymaster are not granted to client domains.
Domains which offer a binderized implementation of Keymaster HAL, such
as hal_keymaster_default domain, are always granted rules targeting
hal_keymaster.

This switches Fingerprint HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Bluetooth HAL.
Domains which are clients of Fingerprint HAL, such as system_server
domain, are granted rules targeting hal_fingerprint only when the
Fingerprint HAL runs in passthrough mode (i.e., inside the client's
process). When the HAL runs in binderized mode (i.e., in another
process/domain, with clients talking to the HAL over HwBinder IPC),
rules targeting hal_fingerprint are not granted to client domains.
Domains which offer a binderized implementation of Fingerprint HAL,
such as hal_fingerprint_default domain, are always granted rules
targeting hal_fingerprint.
NOTE: This commit also removes unnecessary allow rules from
Fingerprint HAL, such access to servicemanager (not hwservicemanager)
and access to keystore daemon over Binder IPC. Fingerprint HAL does
not use this functionality anyway and shouldn't use it either.
Test: Enable fingerprint + PIN secure lock screen, confirm it unlocks

SELinux labeling of filesystem files ignores symlinks. Unfortunately,
/vendor is a symlink on devices without vendor partition
(e.g., hikey). Thus, policy in directories which are used both for
devices with vendor partition and for devices without vendor partition
must be adjusted to match both /vendor and /system/vendor. It is
assumed that the /vendor symlink, if it exists at all, always points
to /system/vendor.
The alternative solution of adjusting vendor policy file labelling
rules at vendor policy build time, when the actual on-device paths are
known, was considered to make it harder to see how files are labelled
by looking solely at the source tree.
Test: Files under /vendor/bin/hw correctly labelled on sailfish,
angler, and a device which uses the /vendor symlink.

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.

hal_*_default daemons whose policy is in common/device-agnostic policy
are provided by the vendor image (see vendor/file_contexts). Thus,
their policy should also reside in the vendor image, rather than in
the system image. This means their policy should live in the vendor
subdirectory of this project.
