Add a neverallow rule asserting that services registered or queried
through servicemanager must have the attribute service_manager_type
or vndservice_manager_type. Attempting to add or query a service which
does not have one of those attributes is malformed policy.

See
https://android-review.googlesource.com/c/platform/system/sepolicy/+/826500/7/private/system_server.te#696
as an example where this occurred.

* changes:
  Separate product_sepolicy.cil out of system sepolicy
  Replace "grep -f" with python util.

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.

grep can potentially run out of memory on Mac builds for large input
files. So we add a python util to handle filtering out files.

We will also need this util to filter plat_sepolicy.cil out of
product_sepolicy.cil

Remove the ability for applications to dlopen() executable code from
their home directory for newer API versions. API versions <= 28 are
uneffected by this change.

When an app uses renderscript to compile a Script instance,
renderscript compiles and links the script using /system/bin/bcc and
/system/bin/ld.mc, then places the resulting shared library into the
application's code_cache directory. The application then dlopen()s the
resulting shared library.

Currently, this executable code is writable to the application. This
violates the W^X property (https://en.wikipedia.org/wiki/W%5EX), which
requires any executable code be immutable.

This change introduces a new label "rs_data_file". Files created by
/system/bin/bcc and /system/bin/ld.mc in the application's home
directory assume this label. This allows us to differentiate in
security policy between app created files, and files created by
renderscript on behalf of the application.

Apps are allowed to delete these files, but cannot create or write these
files. This is enforced through a neverallow compile time assertion.

Several exceptions are added to Treble neverallow assertions to support
this functionality. However, because renderscript was previously invoked
from an application context, this is not a Treble separation regression.

This change is needed to support blocking dlopen() for non-renderscript
/data/data files, which will be submitted in a followup change.
