Embedding Tor #304
Description
The latest stable Tor includes methods allowing embedding of tor directly in applications, via a tor_main C call. e.g. https://trac.torproject.org/projects/tor/ticket/23900
Should investigate the use of these options and this method of launching Tor when using launch() from within txtorcon.
Related: maybe we can make it feasible/easy to embed an entire Tor release (ignoring for now if that's even a good idea)..?
