9e2c4ee557 Fix some dead code in tortls.c
If SSL_CIPHER_find exists, then we won't use either of the two
kludges that would replace it.

f1be33fc00 Another try at fixing 17752
I believe that the final SMARTLIST_DEL_CURRENT was sometimes
double-removing items that had already been removed by
connection_mark_unattached_ap or
connection_ap_handshake_attach_circuit().

The fix here is to prevent iteration over the list that other
functions might be modifying.

fd399ec850 Remove Windows specific data type usage
The Tor code base already contains usage of setsockopt(2) with an int as
their option value without problems.

2d2312d989 Conform to the type signature of setsockopt(2)
According to the POSIX standard the option value is a pointer to void
and the option length a socklen_t. The Windows implementation makes the
option value be a pointer to character and the option length an int.

Casting the option value to a pointer to void conforms to the POSIX
standard while the implicit cast to a pointer to character conforms to
the Windows implementation.

The casts of the option length to the socklen_t data type conforms to
the POSIX standard. The socklen_t data type is actually an alias of an
int so it also conforms to the Windows implementation.

613e0e1c1a Move pending-connection code into connection_ap_about_to_close
It is AP-specific, so that's where it belongs.  This shouldn't have
caused a bug, but due to #17876, we were never actually calling
connection_edge_about_to_close from connection_ap_about_to_close,
causing bug #17874 (aka bug #17752).

1ceb7142a1 A relay now advertises "tunnelled-dir-server" in its descriptor
When a relay does not have an open directory port but it has an
orport configured and is accepting client connections then it can
now service tunnelled directory requests, too. This was already true
of relays with an dirport configured.

We also conditionally stop advertising this functionality if the
relay is nearing its bandwidth usage limit - same as how dirport
advertisement is determined.

978210d5a8 Wait for busy authorities/fallbacks rather than ignoring excluded nodes
Applies the 6c443e987d fix to router_pick_directory_server_impl.

6c443e987d applied to directory servers chosen from the consensus,
and was:
"Tweak the 9969 fix a little

If we have busy nodes and excluded nodes, then don't retry with the
excluded ones enabled. Instead, wait for the busy ones to be nonbusy."

4c1c2a313d Add Fallback Directory Candidate Selection Script
"Tor has included a feature to fetch the initial consensus from nodes
 other than the authorities for a while now. We just haven't shipped a
 list of alternate locations for clients to go to yet.

 Reasons why we might want to ship tor with a list of additional places
 where clients can find the consensus is that it makes authority
 reachability and BW less important.

 We want them to have been around and using their current key, address,
 and port for a while now (120 days), and have been running, a guard,
 and a v2 directory mirror for most of that time."

Features:
* whitelist and blacklist for an opt-in/opt-out trial.
* excludes BadExits, tor versions that aren't recommended, and low
  consensus weight directory mirrors.
* reduces the weighting of Exits to avoid overloading them.
* places limits on the weight of any one fallback.
* includes an IPv6 address and orport for each FallbackDir, as
  implemented in #17327. (Tor won't bootstrap using IPv6 fallbacks
  until #17840 is merged.)
* generated output includes timestamps & Onionoo URL for traceability.
* unit test ensures that we successfully load all included default
  fallback directories.

Closes ticket #15775. Patch by "teor".
OnionOO script by "weasel", "teor", "gsathya", and "karsten".
