The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.
The parts for handling cell formats should be in src/core/or.
The parts for handling onionskin queues should be in src/core/or.
Only the crypto wrapper belongs in src/core/crypto.
When we close a socket via tor_tls_free(), we previously had no way
for our socket accounting logic to learn about it. This meant that
the socket accounting code would think we had run out of sockets,
and freak out.
Fixes bug 27795; bugfix on 0.3.5.1-alpha.
In dirauth:
* bwauth.c reads and uses bandwidth files
* guardfraction.c reads and uses the guardfraction file
* reachability.c tests relay reachability
* recommend_pkg.c handles the recommended-packages lines.
* recv_descs.c handles fingerprint files and processing incoming
routerinfos that relays upload to us
* voteflag.c computes flag thresholds and sets those thresholds on
routerstatuses when computing votes
In control:
* fmt_serverstatus.c generates the ancient "v1 server status"
format that controllers expect.
In nodelist:
* routerstatus_fmt.c formats routerstatus entries for a consensus,
a vote, or for the controller.
Client side, when a descriptor is finally fetched and stored in the cache, we
then go over all pending SOCKS request for that descriptor. If it turns out
that the intro points are unusable, we close the first SOCKS request but not
the others for the same .onion.
This commit makes it that we'll close all SOCKS requests so we don't let
hanging the other ones.
It also fixes another bug which is having a SOCKS connection in RENDDESC_WAIT
state but with a descriptor in the cache. At some point, tor will expire the
intro failure cache which will make that descriptor usable again. When
retrying all SOCKS connection (retry_all_socks_conn_waiting_for_desc()), we
won't end up in the code path where we have already the descriptor for a
pending request causing a BUG().
Bottom line is that we should never have pending requests (waiting for a
descriptor) with that descriptor in the cache (even if unusable).
Fixees #27410.

It is not enough to look at protover for v3 rendezvous support but also we
need to make sure that the curve25519 onion key is present or in other words
that the descriptor has been fetched and does contain it.

There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes
That unit test makes sure we don't have pending SOCK request if the descriptor
turns out to be unusable.
