Add a semanage_mls_enabled() interface to libsemanage so that
semanage/seobject can be rewritten to use it to test whether MLS is
enabled for a given policy store rather than checking the runtime MLS
enabled status, which can be misleading when using semanage on a
SELinux-disabled host or when using semanage on a store other than the
active one. Sample usage:
from semanage import *
handle = semanage_handle_create()
rc = semanage_connect(handle)
rc = semanage_mls_enabled(handle)
