This is an area that apexd can use to store session metadata, which
won't be rolled back with filesystem checkpointing.

The device OS and an installed GSI will both attempt to write
authentication data to the same weaver slots. To prevent this, we can
use the /metadata partition (required for GSI support) to communicate
which slots are in use between OS images.
To do this we define a new /metadata/password_slots directory and define
sepolicy to allow system_server (see PasswordSlotManager) to access it.

In userdebug, for better diagnostics, allow crash_dump to "connect
to" apexd.
Considering apexd is quite powerful, user devices remain restricted.

This is needed in cases SELinux labels are restored under /data/apex by
an external process calling restorecon. In normal condition files under
/data/apex/active retain the label staging_data_file used at their
original creation by StagingManager. However, we observed that the label
might be changed to apex_data_file, which we were able to reproduce by
running restorecon.
Explicitly mark files under /data/apex/active and /data/apex/backup as
staging_data_file.
This CL also remove some stale rules being addressed since.
Test: ran restorecon on files in /data/apex/active, attempted installing
a new apex which triggered the violation when files are linked to
/data/apex/backup. With this CL, the operation succeeds.

Vendors should be able to specify additional cgroups and task profiles
without changing system files. Add access rules for /vendor/etc/cgroups.json
and /vendor/etc/task_profiles.json files which will augment cgroups and
task profiles specified in /etc/cgroups.json and /etc/task_profiles.json
system files. As with system files /vendor/etc/cgroups.json is readable
only by init process. task_profiles.json is readable by any process that
uses cgroups.
