Using tor_free is wrong; event_free must be called for objects obtained from
event_new. Additionally, this slightly simplifies the code.
Also, add a static_assert to prevent further instances.
We only need to rate limit reading on edges for flow control, as per the rate
that comes in the XON from the other side. When we rate limit reading from the
edge source to this rate, we will only deliver that fast to the other side,
thus satisfying its rate request.

The connection type for the listener part was missing from the "is
connection a listener" function.
This lead to our periodic event that retries our listeners to keep
trying to bind() again on an already opened MetricsPort.

Regular relays are about to get their DirPort removed so that reachability
test is not useful anymore
Authorities will still use the DirPort but because network reentry towards
their DirPort is now denied network wide, this test is not useful anymore and
so it should simply be considered reachable at all time.

This is unfortunately massive but both functionalities were extremely
intertwined and it would have required us to actually change the HSv2 code in
order to be able to split this into multiple commits.
After this commit, there are still artefacts of v2 in the code but there is no
more support for service, intro point and HSDir.
The v2 support for rendezvous circuit is still available since that code is
the same for the v3 and we will leave it in so if a client is able to
rendezvous on v2 then it can still transfer traffic. Once the entire network
has moved away from v2, we can remove v2 rendezvous point support.

Turns out, we forgot to add the METRICS connection type fo the finished
flushing handler.

Handle the EOF situation for a metrics connection. Furthermore, if we failed
to fetch the data from the inbuf properly, mark the socket as closed because
the caller, connection_process_inbuf(), assumes that we did so on error.

Some days before this commit, the network experienced a DDoS on the directory
authorities that prevented them to generate a consensus for more than 5 hours
straight.
That in turn entirely disabled onion service v3, client and service side, due
to the subsystem requiring a live consensus to function properly.
We know require a reasonably live consensus which means that the HSv3
subsystem will to its job for using the best consensus tor can find. If the
entire network is using an old consensus, than this should be alright.
If the service happens to use a live consensus while a client is not, it
should still work because the client will use the current SRV it sees which
might be the previous SRV for the service for which it still publish
descriptors for.
If the service is using an old one and somehow can't get a new one while
clients are on a new one, then reachability issues might arise. However, this
is a situation we already have at the moment since the service will simply not
work if it doesn't have a live consensus while a client has one.
