When this method is in place, then any relay which is assigned
MiddleOnly has Exit, V2Dir, Guard, and HSDir cleared
(and has BadExit set if appropriate).
This proposal implements part of Prop335; it's based on a patch
from Neel Chauhan.
When configured to do so, authorities will assign a MiddleOnly flag
to certain relays. Any relay which an authority gives this flag
will not get Exit, V2Dir, Guard, or HSDir, and might get BadExit if
the authority votes for that one.
We keep it around until libevent is fixed, it should be used again. In
the meantime, avoid the compiler to complain of this unused variable.

When we looked, this was the third most frequent message at
PROTOCOL_WARN, and doesn't actually tell us what to do about it.
Now:
* we just log it at info
* we log it only once per circuit
* we report, in the heartbeat, how many times it happens, how many
cells it happens with per circuit, and how long these circuits
have been alive (on average).
Fixes the final part of #40400.
We don't output per-type DNS errors anymore so avoid looping over the
DNS query type and output each errors for them. Before this commit, it
created 3x the same message because we had A, AAAA and PTR type records.

This is due to the libevent bug
https://github.com/libevent/libevent/issues/1219 that fails to return
back the DNS record type on error.
And so, the MetricsPort now only reports the errors as a global counter
and not a per record type.

With this commit, we will only report a general overload state if we've
seen more than X% of DNS timeout errors over Y seconds. Previous
behavior was to report when a single timeout occured which is really too
small of a threshold.
The value X is a consensus parameters called
"overload_dns_timeout_scale_percent" which is a scaled percentage
(factor of 1000) so we can represent decimal points for X like 0.5% for
instance. Its default is 1000 which ends up being 1%.
The value Y is a consensus parameters called
"overload_dns_timeout_period_secs" which is the time period for which
will gather DNS errors and once over, we assess if that X% has been
reached ultimately triggering a general overload signal.

This means that at this commit, tor will stop logging that v2 is
deprecated and treat a v2 address as a bad hostname that we can't use.

Some tests were removed because they were testing something not usable

Some tests remains to make sure that things are indeed disabled.

Relay do not accept both stores and lookups of version 2 descriptor.
This effectively disable version 2 HSDir supports for relays.
