29e0d70814 Bug 1296: Add option+logic to disable CBT learning. 
There are now four ways that CBT can be disabled:

1. Network-wide, with the cbtdisabled consensus param.
2. Via config, with "LearnCircuitBuildTimeout 0"
3. Via config, with "AuthoritativeDirectory 1"
4. Via a state file write failure.

96a0edf373 Rename CircPriorityHalflifeMsec to CircuitPriorityHalflifeMsec 
Everything that accepted the 'Circ' name handled it wrong, so even now
that we fixed the handling of the parameter, we wouldn't be able to
set it without making all the 0.2.2.7..0.2.2.10 relays act wonky.
This patch makes Tors accept the 'Circuit' name instead, so we can
turn on circuit priorities without confusing the versions that treated
the 'Circ' name as occasion to act weird.

9e473bd1be Update idea xxx-using-spdy, based on or-dev discussion 
- Mention potentially negative consequence of server push, combined
  with client caching

- Make the new cell type more generic, allowing other types of
  exit-side transforms (suggested by nickm)

380d00246b Proposal 169: Eliminate TLS renegotiation 
I propose a backward-compatible change to the Tor connection
establishment protocol to avoid the use of TLS
renegotiation.

Rather than doing a TLS renegotiation to exchange
certificates and authenticate the original handshake, this
proposal takes an approach similar to Steven Murdoch's
proposal 124, and uses Tor cells to authenticate the
parties' identities once the initial TLS handshake is
finished.

a007a7c6ba Revise consensus-flavors proposal to better URLs. 
The old flavored consensus URL format made it harder to decode URLs
based on their prefixes, and didn't take into account our "only give
it to me if it's signed by enough authorities" stuff.

0bce0161dd Revise proposal 162: SHA256(x), not SHA256(SHA256(x)) 
The point of doing SHA256 twice is, generally, is to prevent message
extension attacks where an attacker who knows H(A) can calculate
H(A|B).  But for attaching a signature to a document, the attacker
already _knows_ A, so trying to keep them from calculating H(A|B) is
pointless.

e84dc32cb8 correct the spec for the stream_bw event. 
"neonomad" pointed out on or-talk that the order is opposite from the
intuitive order. explain why. we chose to fix the spec rather than the
code because there are controllers like torflow that already expect
the current behavior.

a timeout.

least on directory authority. Un-recommend good-server-descriptor

We were triggering a CLOCK_SKEW controller status event whenever
we connect via the v2 connection protocol to any relay that has
a wrong clock. Instead, we should only inform the controller when
it's a trusted authority that claims our clock is wrong. Bugfix
on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.
