The rest of rephist.c is doing the same kind of unsigned casting. For example
see rep_hist_format_buffer_stats() and rep_hist_format_exit_stats().
The previous switch to %ld made Appveyor fail:

The function in charge of removing duplicate ORPorts from our configured ports
was skipping all non ORPorts port but only for the outer loop thus resulting
in comparing an ORPort with a non-ORPort which lead to problems.
For example, tor configured with the following would fail:
ORPort auto
DirPort auto
Both end up being the same configuration except that one is a OR listener and
one is a Dir listener. Thus because of the missing check in the inner loop,
they looked exactly the same and thus one is removed.

First, this commit moves the launch_dummy_circuit_as_needed() function into
relay_find_addr.c and renames it to relay_addr_learn_from_dirauth(). This is
an attempt to centralize anything relate with address discovery in the right
module.
Second, when building a descriptor and we fail to discover our address,
immediately launch a dummy circuit to an authority in an attempt to learn our
descriptor.
It is still only done every 20 minutes even though the descriptor build is
done every minute. We ought to avoid load on the authority and if we can't
learn in the first place our address from them, chances are more things are
wrong.

Regularly, tor looks if its IP has changed. It does the entire auto discovery
process again. However, it is possible that it does not find anything.
Instead of thinking the IP changed to an unknown address, look at our cache
and see if that value has changed.
The reason for this is because if tor gets its address as a suggestion from a
directory authority, it is because the auto discovery failed and thus that
address should be consider for the IP change check.

Tor now can learn its address from a NETINFO cell coming from an authority.
Thus, instead from launching a dummy descriptor fetch to learn the address
from the directory response (unauthenticated), we simply now launch a one-hop
testing circuit.

Commit c3a0f75796 added this feature for ORPort
that we ignore any port that is not the family of our default address when
parsing the port. So if port_parse_config() was called with an IPv4 default
address, all IPv6 address would be ignored.
That makes sense for ORPort since we call twice port_parse_config() for
0.0.0.0 and [::] but for the rest of the ports, it is not good since a
perfectly valid configuration can be:
SocksPort 9050
SocksPort [::1]:9050
Any non-ORPort only binds by default to an IPv4 except the ORPort that binds
to both IPv4 and IPv6 by default.
The fix here is to always parse all ports within port_parse_config() and then,
specifically for ORPort, remove the duplicates or superseding ones. The
warning is only emitted when a port supersedes another.
A unit tests is added to make sure SocksPort of different family always exists
together.

Typos found with codespell.
Please keep in mind that this should have impact on actual code
and must be carefully evaluated:
src/core/or/lttng_circuit.inc
- ctf_enum_value("CONTROLER", CIRCUIT_PURPOSE_CONTROLLER)
+ ctf_enum_value("CONTROLLER", CIRCUIT_PURPOSE_CONTROLLER)
In the past, only authorities and clients had to use that function because of
the SRV subsystem. However, because of its use in rep_hist_hs_stats_init() it
will now also be used by relays when bootstrapping without a consensus. Make it
do something sensible.
Another approach (instead of using magic values) would be to wait
initialization of HSv3 stats until we get a consensus but that seems messy to
schedule.
Another approach would be to make dirauth_sched_get_configured_interval() also
work for relays (particularly when TestingNetwork is enabled), but that also
seems a good amount of work.
The loop in the earlier patch would invoke undefined behavior in two
ways: First, it would check whether it was looking at a space before
it checked whether the pointer was in-range. Second, it would let a
pointer reach a position _before_ the start of a string, which is
not allowed.
I've removed the assertion about empty messages: empty messages can
be their own warning IMO.
I've also added tests for this formatting code, to make sure it
actually works.
The total number of rendezvous circuit created and the number of established
ones which is a gauge that decreases to keep an updated counter.

At this commit, a new service registers to the module and a store is created.
It also remove itself from the metrics module if it goes away.
In order to hook into the metrics subsystem, this commit attaches the HS
subsystem into the subsystem global list so its get_metrics() call can be
accessible.
HS initialization is still _not_ done through the subsys module as it is
likely require much more testing.

First I began with a set of candidates:
The client's _required_ list starts with all the protocols
supported by every release in 0.2.9-stable through current
master.
The client's _required_ list starts with all the protocols
supported by every release in 0.3.5-stable through current
master.
Everybody's _recommended_ list starts with all the protocols
supported by every release in 0.3.5-stable through current master.
Then I removed the protocol versions that we do not actually want to
require or recommend:
DirCache=1 (deprecated)
HSDir=1, HSIntro=1-3, HSRend=1 (deprecated)
(All HS* protocol requirements for clients)
Link=1-3 (deprecated)
LinkAuth=1 (obsolete)
Relay=1 (obsolete)
Make it possible to specify multiple ConsensusParams torrc
lines.
Now directory authority operators can for example put the
main ConsensusParams config in one torrc file and then add to it
from a different torrc file.
Closes ticket 40164.
