Note: The existing rules allowing socket communication will be removed
once we migrate over to HIDL completely.

The new wifi HAL manages the wlan driver and hence needs to be able to
load/unload the driver. The "wlan.driver.status" is used to indicate the
state of the driver to the rest of the system. There are .rc scripts for
example which wait for the state of this property.

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.
Test: Device boots up fine, Chrome, Play Movies, YouTube, Netflix, work fine.

Previously, we'd restricted WifiService's use of
the kernel's tracing feature to just userdebug_or_eng
builds.
This restriction was in place because the feature
had not yet been reviewed from a privacy perspective.
Now that the feature has passed privacy review, enable
the feature on all builds.
Note that other safeguards remain in place (on all
builds):
- The set of events to be monitored is configured by
init, rather than WifiService (part of system_server).
This privilege separation prevents a compromised
system_server from tracing additional information.
- The trace events are kept only in RAM, until/unless
WifiService receives a dump request. (This would happen,
for example, in the case of adb dumpsys, or generating
a bugreport.)

This switches Wi-Fi HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Wi-Fi HAL.
Domains which are clients of Wi-Fi HAL, such as system_server domain,
are granted rules targeting hal_wifi only when the Wi-Fi 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_wifi are
not granted to client domains.
Domains which offer a binderized implementation of Wi-Fi HAL, such as
hal_wifi_default domain, are always granted rules targeting hal_wifi.
Test: Setup Wizard (incl. adding a Google Account) completes fine with
Wi-Fi connectivity only
Test: Toggle Wi-Fi off, on, off, on
Test: Use System UI to see list of WLANs and connect to one which does
not require a password, and to one which requries a PSK
Test: ip6.me loads fine in Chrome over Wi-Fi

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
with fingerprint or PIN
Test: Disable PIN (and thus fingerprint) secure lock screen
Test: make FingerprintDialog, install, make a fake purchase
Test: Add fingerprint_hidl_hal_test to device.mk, build & add to device,
adb shell stop,
adb shell /data/nativetest64/fingerprint_hidl_hal_test/fingerprint_hidl_hal_test -- all tests pass

This switches DRM HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of DRM HAL.
Domains which are clients of DRM HAL, such as mediadrmserver domain,
are granted rules targeting hal_drm only when the DRM 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_drm
are not granted to client domains.
Domains which offer a binderized implementation of DRM HAL, such as
hal_drm_default domain, are always granted rules targeting hal_drm.
