Merge NS_EXPIRY_SLOP and REASONABLY_LIVE_TIME

These are now the same value (24 hours) so they can be merged into a common header, and the relevant comments removed.

changed milestone to %Tor: unspecified

added cleanup component::core tor/tor easy milestone::Tor: unspecified priority::low refactor severity::trivial status::new tor-client type::enhancement labels

Do they actually mean the same thing, though?

Trac:
Severity: N/A to Normal

Replying to nickm:

Do they actually mean the same thing, though?

I think they do, and if they don't, we should remove the comment in the source that says they should be merged.

Milestone renamed

Trac:
Milestone: Tor: 0.2.??? to Tor: 0.3.???

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

Trac:
Keywords: easy lorax deleted, tor-03-unspecified-201612, lorax, easy added
Milestone: Tor: 0.3.??? to Tor: unspecified

Remove an old triaging keyword.
