Tor stream isolation support

[1cho1ce]

Right now if hydroxide has multiple accounts then connection to all of them will go through the same Tor circuit and it'll cause identity correlation. Using HTTPS_PROXY or torsocks won't help here and stream isolation should be implemented inside hydroxide so all new connections will use a fresh circuit, rather than possibly re-using an existing circuit.
This could be implemented using this package when hydroxide is started with -tor 127.0.0.1:9050 option:

I don't believe plumbing Tor/proxy support to each and every program that uses TCP is a good way forward. I would recommend setting up a system-wide transparent proxy instead (TransPort in Tor config), which makes Tor work similarly to VPNs.
