Motivation: Domain is overly permissive. Start removing permissions
from domain and assign them to the domain_deprecated attribute.
Domain_deprecated and domain can initially be assigned to all
domains. The goal is to not assign domain_deprecated to new domains
and to start removing domain_deprecated where it is not required or
reassigning the appropriate permissions to the inheriting domain
when necessary.

When using MLS (i.e. enabling levelFrom= in seapp_contexts),
certain domains and types must be exempted from the normal
constraints defined in the mls file.  Beyond the current
set, adbd, logd, mdnsd, netd, and servicemanager need to
be able to read/write to any level in order to communicate
with apps running with any level, and the logdr and logdw
sockets need to be writable by apps running with any level.

This change has no impact unless levelFrom= is specified in
seapp_contexts, so by itself it is a no-op.

Init never uses binder, so allowing binder related operations
for init never makes sense. Disallow all binder opertions for
init.

This change expands on commit a730e50b,
disallowing any init binder operation, not just call operations, which
may be accidentally added by blindly running audit2allow.

Add a service_mananger class with the verb add.
Add a type that groups the services for each of the
processes that is allowed to start services in service.te
and an attribute for all services controlled by the service
manager. Add the service_contexts file which maps service
name to target label.

This change removes the permissive line from unconfined
domains. Unconfined domains can do (mostly) anything, so moving
these domains into enforcing should be a no-op.

The following domains were deliberately NOT changed:
1) kernel
2) init

In the future, this gives us the ability to tighten up the
rules in unconfined, and have those tightened rules actually
work.

When we're ready to tighten up the rules for these domains,
we can:

1) Remove unconfined_domain and re-add the permissive line.
2) Submit the domain in permissive but NOT unconfined.
3) Remove the permissive line
4) Wait a few days and submit the no-permissive change.

For instance, if we were ready to do this for adb, we'd identify
a list of possible rules which allow adbd to work, re-add
the permissive line, and then upload those changes to AOSP.
After sufficient testing, we'd then move adb to enforcing.
We'd repeat this for each domain until everything is enforcing
and out of unconfined.

This prevents denials from being generated by the base policy.
Over time, these rules will be incrementally tightened to improve
security.

The binder_transfer_binder hook was changed in the kernel, obsoleting
the receive permission and changing the target of the transfer permission.
Update the binder-related policy to match the revised permission checking.
