8b1d45201d installd has moved on to Binder; goodbye socket! 
After a series of recent commits, installd has fully migrated over
to Binder, and all socket-based communication has been removed.

Test: builds, boots, apps install fine, pre-OTA dexopt works
Bug: 13758960, 30944031

c27c23fbdb /dev/port does not seem to be used, adding in rules to confirm. 
Only init and ueventd have any access to /dev/port, and neither should
have any use for it. As it stands, leaving port in just represents
additional attack surface with no useful functionality, so it should be
removed if possible, not only from Pixel devices, but from all Android
devices.

Test: The phone boots successfully

3319d5ee16 Move hal_light to attribute. 
HAL policy defines how the platform and a given HAL interact, but not how the
HAL is implemented.  This policy should be represented as an attribute that all
processes implementing the HAL can include.

Bug: 32123421
Test: Builds.

dc43f7cd84 Add the "webview_zygote" domain. 
The webview_zygote is a new unprivileged zygote and has its own sockets for
listening to fork requests. However the webview_zygote does not run as root
(though it does require certain capabilities) and only allows dyntransition to
the isolated_app domain.

cc39f63773 Split general policy into public and private components. 
Divide policy into public and private components.  This is the first
step in splitting the policy creation for platform and non-platform
policies.  The policy in the public directory will be exported for use
in non-platform policy creation.  Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.

Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal.  For now, almost all types and
avrules are left in public.

Test: Tested by building policy and running on device.
