    Add security hooks to the binder and implement the hooks for SELinux.
    The security hooks enable security modules such as SELinux to implement
    controls over binder IPC.  The security hooks include support for
    controlling what process can become the binder context manager
    (binder_set_context_mgr), controlling the ability of a process
    to invoke a binder transaction/IPC to another process (binder_transaction),
    controlling the ability of a process to transfer a binder reference to
    another process (binder_transfer_binder), and controlling the ability
    of a process to transfer an open file to another process (binder_transfer_file).
    
    These hooks have been included in the Android kernel trees since Android 4.3.
    
    (Updated to reflect upstream relocation and changes to the binder driver,
    changes to the LSM audit data structures, coding style cleanups, and
    to add inline documentation for the hooks).
