nginx: add support for stream proxying
Nginx supports, with the "stream" family of modules, acting as a (reverse) proxy for arbitrary data streams. This PR adds a "stream" build option, enabled by default, that will configure nginx for stream proxying. Offloading encryption responsibilities to an nginx strem proxy represents a good use case for this feature.
