For consistency with APKs, signature verification is performed
in the system_server. This includes checking that the signature of
an updated install matches the signature of the active package that
it updates. For this, it requires search access to /data/apex and
read access to the files under that directory.

This reverts commit 9eb3b8ffdf.
Reason for revert: We are deciding for now not to make StagingManager a fully-fledged binder service, as it will only be accessed by PackageInstaller. We might re-evaluate this decision later if needed.

There are many permission related APIs currently handled by the
package manager service. These are simply pass throughs from the
package manager service to an internal API defined by the
permission manager service. Instead of this multi-hop, we want
to open the permission manager service directly to apps. For
legacy, we won't be able to remove the APIs from PackageManager,
but, the implementation should go directly to the Permission
Manager Service.

sed "-i" flag on Mac has different syntax than on Linux. Replace use of

A simple fix like this should suffice for this case, but ideally, we

Product-specific sepolicy will be installed into /product/etc/selinux/*.
This change separates out /product/etc/selinux/product_sepolicy.cil out
of system sepolicy.
This file is merged into precompiled_sepolicy at build-time. In case
precompiled_sepolicy can't be used (e.g. system-only-ota), init wll
merge this file with the rest of the sepolicy at runtime.
I left TODOs to separate other product-specific SELinux artifacts out of
system.
