Coalesce a number of allow rules replicated among multiple
app domains.
Get rid of duplicated rules already covered by domain, appdomain,
or platformappdomain rules.
Split the platformappdomain rules to their own platformappdomain.te
file, document them more fully, and note the inheritance in each
of the relevant *_app.te files.
Generalize isolated app unix_stream_socket rules to all app domains
to resolve denials such as:
avc: denied { read write } for pid=11897 comm="Binder_2" path="socket:[203881]" dev="sockfs" ino=203881 scontext=u:r:release_app:s0 tcontext=u:r:untrusted_app:s0 tclass=unix_stream_socket
avc: denied { getattr } for pid=11990 comm=4173796E635461736B202334 path="socket:[203881]" dev="sockfs" ino=203881 scontext=u:r:release_app:s0 tcontext=u:r:untrusted_app:s0 tclass=unix_stream_socket
