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.
Deprecated in 0.2.9.2-alpha, this commits changes it as OBSOLETE() and cleans

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.

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.
This patch refactors our streaming compression code to allow us to
extend it with non-zlib/non-gzip based compression schemas.

Note down in the routerstatus_t of a node if the router supports the HSIntro=4
version for the ed25519 authentication key and HSDir=2 version for the v3
descriptor supports.

The old implementation had duplicated code in a bunch of places, and
it interspersed spool-management with resource management. The new
implementation should make it easier to add new resource types and
maintain the spooling code.
Closing ticket 21651.
This patch changes the way we decide when to check for whether it's time
to rotate and/or expiry our onion keys. Due to proposal #274 we can now
have the keys rotate at different frequencies than before and we thus
do the check once an hour when our Tor daemon is running in server mode.
This should allow us to quickly notice if the network consensus
parameter have changed while we are running instead of having to wait
until the current parameters timeout value have passed.

This patch adds an API to get the current grace period, in days, defined
as the consensus parameter "onion-key-grace-period-days".
As per proposal #274 the values for "onion-key-grace-period-days" is a
default value of 7 days, a minimum value of 1 day, and a maximum value
defined by other consensus parameter "onion-key-rotation-days" also
defined in days.
See: https://bugs.torproject.org/21641
This patch turns `MIN_ONION_KEY_LIFETIME` into a new function
`get_onion_key_lifetime()` which gets its value from a network consensus
parameter named "onion-key-rotation-days". This allows us to tune the
value at a later point in time with no code modifications.
We also bump the default onion key lifetime from 7 to 28 days as per
proposal #274.

This patch makes us store the number of sent and received RELAY_DATA
cells used for directory connections. We log the numbers after we have
received an EOF in connection_dir_client_reached_eof() from the
directory server.
Stop modifying the value of our torrc option HiddenServiceStatistics just
because we're not a bridge or relay. This bug was causing Tor Browser users to
write "HiddenServiceStatistics 0" in their torrc files as if they had chosen
to change the config.

The server-side clipping now clamps to one of two values, both
for what to report, and how long to cache.
Additionally, we move some defines to dns.h, and give them better
names.
When marking for close a circuit, the reason value, a integer, was assigned to
a uint16_t converting any negative reasons (internal) to the wrong value. On
the HS side, this was causing the client to flag introduction points to be
unreachable as the internal reason was wrongfully converted to a positive
16bit value leading to flag 2 out of 3 intro points to be unreachable.
