Add a new permission to have access to Gal Provider

     * directory provider URIs by themselves. This level of indirection allows

     * Contacts Provider to implement additional system-level features and

     * optimizations. Access to Contacts Provider is protected by the

     * READ_CONTACTS permission, but access to the directory provider is not.

     * Therefore directory providers must reject requests coming from clients

     * other than the Contacts Provider itself. An easy way to prevent such

     * unauthorized access is to check the name of the calling package:

     * READ_CONTACTS permission, but access to the directory provider is protected by

     * BIND_DIRECTORY_SEARCH. This permission was introduced at the API level 17, for previous

     * platform versions the provider should perform the following check to make sure the call

     * is coming from the ContactsProvider:

     * <pre>

     * private boolean isCallerAllowed() {

     *   PackageManager pm = getContext().getPackageManager();

        android:label="@string/permlab_writeContacts"

        android:description="@string/permdesc_writeContacts" />

    <!-- Allows an application to execute contacts directory search.

         This should only be used by ContactsProvider. -->

    <!-- @hide -->

    <permission android:name="android.permission.BIND_DIRECTORY_SEARCH"

        android:permissionGroup="android.permission-group.PERSONAL_INFO"

        android:protectionLevel="signature" />

    <!-- Allows an application to read the user's call log. -->

    <permission android:name="android.permission.READ_CALL_LOG"
