Subject: [PATCH] Set default pid_filename based on service name

This makes pid_filename directive no longer need to be set explicitly to
the service name in multi-tenant installations. Unless the default value
has been replaced with --with-pidfile=Foo it will use the service name
as the .pid filename.
