/* Load a source policy into p. policydb_init will called within this function.
 * 
 * Example: test_load_policy(p, POLICY_BASE, 1, "foo", "base.conf") will load the
 *  policy "policies/foo/mls/base.conf" into p.
 *
 * Arguments:
 *  p            policydb_t into which the policy will be read. This should be
 *                malloc'd but not passed to policydb_init.
 *  policy_type  Type of policy expected - POLICY_BASE or POLICY_MOD.
 *  mls          Boolean value indicating whether an mls policy is expected.
 *  test_name    Name of the test which will be the name of the directory in
 *                which the policies are stored.
 *  policy_name  Name of the policy in the directory.
 *
 * Returns:
 *  0            success
 * -1            error - the policydb will be destroyed but not freed.
