Finally admitting that 0.3.??? was a euphemism for Tor: unspecified all along.

Remove an old triaging keyword.

The tor-core keyword doesn't really make sense now that we have "Core Tor/Tor" for component.

Better than
SCM_CREDENTIALS/SCM_CREDSwould be to use the equally non-portable (but easier to use) socket options that return the relevant tuple.SO_PEERCREDon Linux,LOCAL_PEERCRED(SOL_SOCKET) on FreeBSD,LOCAL_PEERCRED(SOL_LOCAL) on Darwin.This is a dead trivial amount of code to add, so I could see it being really nice for 0.2.7.x if someone has time to write a good implementation of it (and I may, if I can spare a hour or two). It's particularly appealing for torsocks, since once AF_UNIX backed socket support lands there, it will automagically get strong-ish isolation.
