Update Standards-Version to 3.9.5 (no changes needed)
Add if-up script to reload firewall

Reload firewall rules if a new interface comes up. This is primarily to
support DNS names in the network whitelist. If no DNS resolver is
reachable during system startup, these rules are not applied. Reloading
the firewall rules retries to resolve these names.
Don't abort if a whitelist rule fails

If a whitelist rule failed (eg. because the DNS name referenced was not
resolveable) the script just stopped and did not add any further rules.
The new code only reports an error message but continues to load the
rest of the rules. If any rule failed, the return code is 1.

This also makes the script dependent on bash because POSIX shell
lacks some features needed.
Start tinyproxy even if some firewall rules fail

The firewall script returns an error if some of the whitelist rules
could not be applied. Thus tinyproxy was not started. But with the new
if-up script the firewall may become fully functional later on and
tinyproxy should be started anyway.
