a4c8531260 refactor: using get_uptime() (and reset_uptime()) consistently.
Using get_uptime() and reset_uptime() instead of
accessing stats_n_seconds_working directly.

stats_n_seconds_working is not extern anymore.

5ea993fa5a Clarify directory and ORPort checking functions.
In order to make the OR and dir checking functions in router.c less confusing
we renamed some functions and splitted consider_testing_reachability() into
router_should_check_reachability() and router_do_reachability_checks(). Also we
improved the documentation.

Fixes #18918.

3907faf2fd New accessors for keydir/cachedir access
This patch is a result of auditing all of our uses of
get_datadir_fname() and its kin, and dividing them into cache vs
keys vs other data.

The new get_keydir_fname() and get_cachedir_fname() functions don't
actually do anything new yet.

9f2efd02a1 Minimal implementation of bridge-distribution-request
Just advertise the line when we're a bridge, using "any" if we're
published or "none" if we aren't.

This is done in lieu of a full backport of #18329.

ebab521525 Add new BridgeDistribution config option

80d3887360 Refactor node lookup APIs to take flags
Right now there's a single warn_if_unnamed flag for
router_get_consensus_status_by_nickname() and
node_get_by_nickname(), that is nearly always 1.  I've turned it
into an 'unsigned' bitfield, and inverted its sense.  I've added the
flags argument to node_get_by_hex_id() too, though it does nothing
there right now.

I've removed the router_get_consensus_status_by_nickname() function,
since it was only used in once place.

This patch changes the warning behavior of GETINFO ns/name/<name>,
since all other name lookups from the controller currently warn.

Later I'm going to add more flags, for ed25519 support.

rephist: Remove unused crypto_pk statistics.
These statistics were largely ununsed, and kept track of statistical information
on things like how many time we had done TLS or how many signatures we had
verified.  This information is largely not useful, and would only be logged
after receiving a SIGUSR1 signal (but only if the logging severity level was
less than LOG_INFO).

 * FIXES #19871.
 * REMOVES note_crypto_pk_op(), dump_pk_op(), and pk_op_counts from
   src/or/rephist.c.
 * REMOVES every external call to these functions.

a9be768959 Bugfix: Regenerate more certificates when appropriate
Previously we could sometimes change our signing key, but not
regenerate the certificates (signing->link and signing->auth) that
were signed with it.  Also, we would regularly replace our TLS x.509
link certificate (by rotating our TLS context) but not replace our
signing->link ed25519 certificate.  In both cases, the resulting
inconsistency would make other relays reject our link handshakes.

Fixes two cases of bug 22460; bugfix on 0.3.0.1-alpha.

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.

853b54dea4 Add periodic timer for expiring old onion keys.
This patch adds a new timer that is executed when it is time to expire
our current set of old onion keys. Because of proposal #274 this can no
longer be assumed to be at the same time we rotate our onion keys since
they will be updated less frequently.

d88f10cdf2 Add API to query the current onion key grace period.
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.

23ae5b655b Make MIN_ONION_KEY_LIFETIME a consensus parameter defined value.
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.
