Add support for -R (recurse) to init chown builtin.

This is helpful for setting ownerships on entire directory trees,
such as sysfs and selinuxfs, particularly when the precise set of
files is dynamically generated at runtime.

Allow system UID to setenforce and set booleans for SELinux.

Allow system UID to setenforce and set booleans for SELinux.
Boolean ownerships must also be reset upon policy reload as
the boolean files in selinuxfs are regenerated to match the new policy.
run-as:  Get seinfo from packages.list and pass to libselinux.
Add persist.mac_enforcing_mode property

Change setsebool syntax to be consistent with other init built-ins.

Change setsebool syntax from name=value to name value.
This is to make it consistent with setprop and similar commands.
Update both the init built-in command and the toolbox command
for consistency.

Create a new location for /data policy files

Updating the location of policy files from
/data/system to /data/securtiy. Requires a
new directory to be created by init and an
update to the location of the
property_contexts file for property service.

AID_AUDIT will be used for an audit daemon for gathering
and controlling the Linux audit subsystem.

Auditd initial commit

Initial commit for an audit daemon that
writes kernel audit messages to a log
file. The daemon runs in uid "audit" or
AID_AUDIT.

The log files are located at /data/misc/audit/
The daemon maintains two files at this location:
audit.log and optionally audit.old. On boot (
if the file is non-zero in size), or
when a fixed threshold is hit, the daemon rotates
audit.log to audit.old.

Optionally, if passed the -k option, the daemon polls
dmesg for all lines that contain "audit" and writes
them into the log. After that it continues to operate
as normal, receiving the messages from the netlink
socket.

Add support for socket security context specification.

Add an optional argument to the socket option for specifying
a SELinux security context for the socket.  Normally the socket
security context is automatically computed from the service security
context or set using the seclabel option, but this facility allows
dealing with two scenarios that cannot be addressed using the existing
mechanisms:
1) Use of logwrapper to wrap a service.
In this case, init cannot determine the service security context
as it does not directly execute it and we do not want logwrapper
to run in the same domain as the service.

2) Situations where a service has multiple sockets and we want to
label them distinctly.

toolbox: Add levelFromUid categorization support to restorecon

This is necessary for the app data relabeling on migrated devices
to include the proper app context. Freshly installed apps get this
done automagically, as do newly created files.

fs_mgr: Drop the context mount option from non-selinux builds

Transitioning devices may have the context option present in the
fstab, even if we're not doing selinux builds.
Since we don't set or even create the contexts on those builds,
this will make mount fail, and either the mountpoint ends up absent,
or boot fails entirely
