(breaks vendor blobs, will have to be regenerated
after this CL)
This moves mediacodec to vendor so it is replaced with
hal_omx_server. The main benefit of this is that someone
can create their own implementation of mediacodec without
having to alter the one in the tree. mediacodec is still
seccomp enforced by CTS tests.

We install all default hal implementations in /vendor/bin/hw along with
a few domains that are defined in vendor policy and installed in
/vendor. These files MUST be a subset of the global 'vendor_file_type'
which is used to address *all files installed in /vendor* throughout the
policy.

As a result, Keymaster and DRM HALs are permitted to talk to tee domain
over sockets. Unfortunately, the tee domain needs to remain on the
exemptions list because drmserver, mediaserver, and surfaceflinger are
currently permitted to talk to this domain over sockets.
We need to figure out why global policy even defines a TEE domain...

Vendor and system components are only allowed to share files by
passing open FDs over HIDL. Ban all directory access and all file
accesses other than what can be applied to an open file:
stat/read/write/append.
This commit marks core data types as core_data_file_type and bans
access to non-core domains with an exemption for apps. A temporary
exemption is also granted to domains that currently rely on
access with TODOs and bug number for each exemption.

On PRODUCT_FULL_TREBLE devices, non-vendor domains (coredomain) and
vendor domain are not permitted to connect to each other's sockets.
There are two main exceptions: (1) apps are permitted to talk to other
apps over Unix domain sockets (this is public API in Android
framework), and (2) domains with network access (netdomain) are
permitted to connect to netd.
This commit thus:
* adds neverallow rules restricting socket connection establishment,
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"socket_between_core_and_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 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.

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.
