b619f1333e Correct status of optional interface during 'disable' 
- If <interface>.status contains 0 but the interface's routing table has
  been deleted, then 'disable' would not correct the file.

badf2fc9f0 Support SAFESTOP under systemd 
By default, in Debian and its derivatives, stopping the Shorewall
service executes `/sbin/shorewall clear`.

The `SAFESTOP` setting in /etc/default/shorewall is intended to stop the
service by calling `/sbin/shorewall stop`.

However, the systemd service files do not support this.  Instead,
install a shell-script that sources /etc/default/shorewall and honours
`SAFESTOP` when stopping Shorewall and patch the service files to call
it.

5e8ce7d073 lib.cli-std: fix two shell errors when AUTOMAKE is false 
If `AUTOMAKE` is set to `no` in the config file, it is normalized to the
empty string.

This leads to two errors if `find` is provided by Busybox.

There is a conditional where `$AUTOMAKE` is not quoted when compared to
`recursive` leading to the following error:

  /usr/share/shorewall/lib.cli-std: line 398: [: =: unary operator expected

In contrast to the non-Busybox case, we don't check for an empty
`$AUTOMAKE` before passing it as an argument to `-maxdepth`, leading to:

  /usr/bin/find: Expected a positive decimal integer argument to -maxdepth, but got -type

Refactor the conditionals to eliminate code duplication and fix these two
bugs.

450a16f730 Destroy the temporary IP set in the cleanup function 
In the IP set capability tests, there is a race condition which
might prevent the removal of the temporary IP set immediately
after flushing the chain that uses this IP set: even though the
rules which used the IP set were deleted, the IP set might still
appear to be “in use by a kernel component.”

In case this happens, we add an extra call to `ipset -X` in the
`cleanup_iptables()` function, just to be sure that the temporary
IP set is indeed destroyed when the compiler exits.
