Without this change, any selinux warning you might get when running
dumpstate from init do not show up when running from the shell
as root. This change makes them run the same.

On 64 bit systems, all requests will first go to the 64 bit debuggerd
which will redirect to the 32 bit debuggerd if necessary. This avoids
any permissions problems where a java process needs to be able to
read the elf data for executables. Instead the permissions are granted
to debuggerd instead.

Also remove the permissions to read the /system/bin executables from
dumpstate since they aren't necessary any more.

The list of processes comes from frameworks/native/cmds/dumpstate/utils.c.
dumpstate calls dump_backtrace_to_file() for each such process, which
asks debuggerd to dump the backtrace.

This was originally to limit the ability to relabel files to
particular types given the ability of all domains to relabelfrom
unlabeled files.  Since the latter was removed by
Ied84f8b4b1a0896c1b9f7d783b7463ce09d4807b, this no longer serves
any purpose.

Replace * or any permission set containing create with
create_socket_perms or create_stream_socket_perms.

Add net_domain() to all domains using network sockets and
delete rules already covered by domain.te or net.te.

For netlink_route_socket, only nlmsg_write needs to be separately
granted to specific domains that are permitted to modify the routing
table.   Clarification:  read/write permissions are just ability to
perform read/recv() or write/send() on the socket, whereas nlmsg_read/
nlmsg_write permissions control ability to observe or modify the
underlying kernel state accessed via the socket.
See security/selinux/nlmsgtab.c in the kernel for the mapping of
netlink message types to nlmsg_read or nlmsg_write.

Delete legacy rule for b/12061011.

This change does not touch any rules where only read/write were allowed
to a socket created by another domain (inherited across exec or
received across socket or binder IPC).  We may wish to rewrite some or all
of those rules with the rw_socket_perms macro but that is a separate
change.

Permissive domains are only intended for development.
When a device launches, we want to ensure that all
permissive domains are in, at a minimum, unconfined+enforcing.

Add FORCE_PERMISSIVE_TO_UNCONFINED to Android.mk. During
development, this flag is false, and permissive domains
are allowed. When SELinux new feature development has been
frozen immediately before release, this flag will be flipped
to true. Any previously permissive domains will move into
unconfined+enforcing.

This will ensure that all SELinux domains have at least a
minimal level of protection.

Unconditionally enable this flag for all user builds.
