b2cb3c33ac Tidy or_options_t by removing obsolete options.
Nothing was setting or inspecting these fields, and they were marked
as OBSOLETE() in config.c -- but somehow we still had them in the
or_options_t structure.  Ouch.

b867295ffd config: Parse ports at the start of options_validate()
There was a bug that got exposed with the removal of ORListenAddress. Within
server_mode(), we now only check ORPort_set which is set in parse_ports().

However, options_validate() is using server_mode() at the start to check if we
need to look at the uname but then the ORPort_set is unset at that point
because the port parsing was done just after. This commit fixes that.

b8abedfeee Split MyFamily into user-specified version and normalized version
This change prevents a no-longer-supported behavior where we change
options that would later be written back to torrc with a SAVECONF.

Also, use the "Pointer to final pointer" trick to build the
normalized list, to avoid special-casing the first element.

687a85950a Cache netflow-related consensus parameters.
Checking all of these parameter lists for every single connection every second
seems like it could be an expensive waste.

Updating globally cached versions when there is a new consensus will still
allow us to apply consensus parameter updates to all existing connections
immediately.

76c9330f9d Bug 17604: Converge on only one long-lived TLS conn between relays.
Accomplished via the following:

1. Use NETINFO cells to determine if both peers will agree on canonical
   status. Prefer connections where they agree to those where they do not.
2. Alter channel_is_better() to prefer older orconns in the case of multiple
   canonical connections, and use the orconn with more circuits on it in case
   of age ties.

Also perform some hourly accounting on how many of these types of connections
there are and log it at info or notice level.

d5a151a067 Bug 17592: Clean up connection timeout logic.
This unifies CircuitIdleTimeout and PredictedCircsRelevanceTime into a single
option, and randomizes it.

It also gives us control over the default value as well as relay-to-relay
connection lifespan through the consensus.

b0e92634d8 Netflow record collapsing defense.
This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.

Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.

The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.

The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.

Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.
