Modify installd to set the SELinux security context on package directories.

installd already sets the UID/GID/mode for package directories.
Extend it to also call libselinux to set the SELinux security context.

Add seinfo parsing to PackageManagerService.

This patch set allows the PMS to parse the
mac_permissions.xml file which contains the
seinfo values. Each package that is installed
on the device will be assigned an seinfo value
based on policy. This seinfo value will help label
the app process and data directory. Modifications
also include, adjustments to ApplicationInfo.java
to store the seinfo tag per package, adjustments
to installd to communicate the seinfo tag to
libselinux, and finally a set of unit tests.

Add APIs to allow Device Admins to change SELinux settings

These calls, added to the Device Admin API, will allow Device Admin apps
to change various SELinux settings, including:
* Toggling SELinux enforcing and permissive modes
* Toggle SELinux booleans
* Load a new SELinux policy file (sepolicy)
* Load new SELinux context files ({property,file,seapp}_contexts)

In order to use these APIs, a Device Admin must first request
USES_POLICY_ENFORCE_SELINUX, then become a SELinux Admin by calling
setSELinuxAdmin(). All other set* calls relevant to SELinux are guarded
by a check against whether the admin is a SELinux Admin.

Otherwise, the style of the set* calls are very similar to the other
calls setting device policy in the Device Admin API. That is, these
calls change the Admin's internal state and then call a sync method to
update the device's state to the Admin's state.

Proper security labeling of multi-user data directories.

This patch covers 2 cases. When an app is installed
and the resulting data directory is created for all
existing users. And when a new user is created and
all existing app data directories are created for
the new user.

Update location of policy files

The location of policy files has changed from
/data/system to /data/security.

Also, a name change to mmac enforcing property
name to place it under persist.mmac. namesepace.

enforcing mode.

Change DPMS code to accommodate enforce states on boot.

We need to respect if setenforce (selinux enforce), setsebool (booleans),
or setprop (mmac enforce) are set in the any of the init.rc files.
This set of changes will allow the init.rc values to win over any
potential device admin wishes.

Bring install-time code inline with AOSP.

Recent submissions to AOSP rework some of the

Bring our maintained version inline with
those changes while still allowing policy
to dictate all seinfo values regardless
of location.
