                                      mandos-client.
* mandos-client.c (raise_privileges): Moved to top of file.
                  (raise_privileges_permanently): - '' -
                  (lower_privileges): - '' -
                  (lower_privileges_permanently): - '' -
  (add_remove_local_route, add_local_route, remove_local_route): New.

                       and network hook executables.  Move redirecting
                       of stdout and stderr to as late as possible
                       before fexecve().
  (main): Use O_DIRECTORY and O_PATH when opening temporary directory.
* plugins.d/mandos-client.xml (ENVIRONMENT): Document usage of the
