David Goulet 5f009a59da conn: MetricsPort listener is a listener port
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.

Closes #40370

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

David Goulet 01c4abc2d4 conn: Properly close MetricsPort socket on EOF
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.

Alexander Færøy ad08743299 Rename OUTBOUND_ADDR_EXIT_AND_OR to OUTBOUND_ADDR_ANY.
This patch renames the enumeration value in `outbound_addr_t` from
`OUTBOUND_ADDR_EXIT_AND_OR` to `OUTBOUND_ADDR_ANY` since with the
arrival of `OUTBOUND_ADDR_PT` it no longer makes sense to call the
fallback value for "Exit and OR". Instead we rename it to "any".

David Goulet ea339227c2 conn: Remove assert on new listener connection when retrying
Opening a new listener connection can fail in many ways like a bind()
permission denied on a low port for instance.

And thus, we should expect to handle an error when creating a new one instead
of assert() on it.

To hit the removed assert:

  ORPort 80
  KeepBindCapabilities 0

Start tor. Then edit torrc:

  ORPort <some-IP>:80

HUP tor and the assert is hit.

Nick Mathewson b417594dbc Replace several C identifiers for ticket 18106.
We used to have a single boolean, "FascistFirewall".  Ages ago, in
tickets #17840 and #9067, we added an improved "ReachableAddresses"
mechanism.  It's time to rename related identifiers in the code for
consistency.  This closes #18106.

Nick Mathewson ceb6585a4b Treat all extorport connections with un-set addresses as remote
Without this fix, if an PT forgets to send a USERADDR command, that
results in a connection getting treated as local for the purposes of
rate-limiting.

If the PT _does_ use USERADDR, we still believe it.

David Goulet 7795dd7ef6 addr: Refactor last resolved address cache accessors
Series of things done in this commit:

  1. Rename the functions to better reflect the namespace of the file.

  2. Make both reset and get function to operate on the last_resolved_addrs
     cache that is per family.

  3. Make the get function to take a tor_addr_t.

  4. Change all callsite to use the new convention.
