In libprocessgroup, we want to only send signals once to processes,
particularly for SIGTERM.  We must send the signal both to all
processes within a POSIX process group and a cgroup.  To ensure that
we do not duplicate the signals being sent, we check the processes in
the cgroup to see if they're in the POSIX process groups that we're
killing.  If they are, we skip sending a second signal.  This requires
getpgid permissions, hence this SELinux change.

This is used to persist RFC 7217 stable secrets across device reboots.

First submit caused a merge conflict. This revision replaces netd_prop
with a more unique name netd_stable_secret_prop.

Test: as follows
    - Manually tested that stable_secret is generated on first use and
      persists until reset of user data partition (factory reset).
    - Tested that "adb shell getprop" was denied access to
      persist.netd.stable_secret after running "adb unroot".

tombstoned allows dumpstate to install "intercepts" to java trace
requests for a given process. When an "intercept" is installed, all
trace output is redirected to a pipe provided by dumpstate instead
of the default location (usually in /data/anr or /data/tombstone).

Note that these processes are already granted "write" and "getattr"
on dumpstate:fifo_file in order to communicate with dumpstate; this
change adds "append" to the existing set of permissions.

Applications connect to tombstoned via a unix domain socket and request
an open FD to which they can write their traces. This socket has a new
label (tombstoned_java_trace_socket) and appdomain and system_server are
given permissions to connect and write to it.

Apps no longer need permissions to open files under /data/anr/ and
these permissions will be withdrawn in a future change.

Remove SELinux access from domain_deprecated. Access to SELinux APIs can
be granted on a per-domain basis.

Remove appdomain access to SELinux APIs. SELinux APIs are not public and
are not intended for application use. In particular, some exploits poll
on /sys/fs/selinux/enforce to determine if the attack was successful,
and we want to ensure that the behavior isn't allowed. This access was
only granted in the past for CTS purposes, but all the relevant CTS
tests have been moved to the shell domain.

(cherry picked from commit a0d3ff8e)

The service "storaged" implememnts a dump() interface for
dumpsys, and thus it needs to write its state to the fd
provided by dumpstate.

To correct this, and fix dumpstate, allow the permission.
