501fc3bbc6 protovers: during voting, assert that we are not voting to shut down.
As a failsafe, we should make sure that no authority ever votes for
a set of protocol versions that it does not itself support.

0a3da5ce79 prop264: sometimes check client _and_ server versions.
As before, we check server protocols whenever server_mode(options)
is true and we check client protocols whenever server_mode(options)
is false.

Additionally, we now _also_ check client protocols whenever any
client port is set.

e525f5697f Use protocols to see when EXTEND2 support exists.
(Technically, we could just remove extend2 cell checking entirely,
since all Tor versions on our network are required to have it, but
let's keep this around as an example of How To Do It.)

90a6fe318c Vote on 'proto' lines and include them after 'v' lines.
(Despite the increased size of the consensus, this should have
approximately zero effect on the compressed consensus size, since
the "proto" line should be completely implied by the "v" line.)

c1be8f9d57 Basic backend for the protocol-versions voting algorithm.
[This is a brute-force method that potentially uses way too much
RAM. Need to rethink this a little. Right now you can DOS an
authority by saying "Foo=1-4294967295".]

951638a06d Fix pthread_cond_timedwait() on OSX Sierra
Sierra provides clock_gettime(), but not pthread_condattr_setclock.
So we had better lot try to use CLOCK_MONOTONIC as our source for
time when waiting, since we ccan never actually tell the condition
that we mean CLOCK_MONOTONIC.

This isn't a tor bug yet, since we never actually pass a timeout to
tor_cond_wait() outside of the unit tests.

e4aaf76660 When clearing cells from a circuit for OOM reasons, tell cmux we did so.
Not telling the cmux would sometimes cause an assertion failure in
relay.c when we tried to get an active circuit and found an "active"
circuit with no cells.

Additionally, replace that assert with a test and a log message.

Fix for bug 20203. This is actually probably a bugfix on
0.2.8.1-alpha, specifically my code in 8b4e5b7ee9 where I
made circuit_mark_for_close_() do less in order to simplify our call
graph. Thanks to "cypherpunks" for help diagnosing.

0baa276ea9 Coverity warning fix: let coverity tell we're closing sockets
Our use of the (mockable) tor_close_socket() in the util/socket_..
tests confused coverity, which could no longer tell that we were
actually closing the sockets.

2196c7ad64 Remove current_consensus macro.
It's a macro that calls down to a function whose behavior has been
getting progresively more complicated.... but we named it as if it
were a variable.  That's not so smart.  So, replace it with a
function call to a function that was just doing "return
current_consensus".

Fixes bug 20176.
