62b709bc26 Release ownership of the dummy socket that tortls_nss.c will close
Related to #27795 -- since NSS will close the socket, we must not
count it as owned by Tor.

f25323fe3f Fix socket accounting with ORConn sockets.
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.

b54a5e704f Split most of dirserv.c into several new modules
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.

fa6d5dd268 hs-v3: Close all SOCKS request on descriptor failure
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.

e3713f17fb node: Make node_supports_v3_rendezvous_point() also check for the key
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.

Fixes #27797.

7ace8d5a61 Assert that some trunnel _new() functions return non-NULL
The trunnel functions are written under the assumption that their
allocators can fail, so GCC LTO thinks they might return NULL.  In
point of fact, they're using tor_malloc() and friends, which can't
fail, but GCC won't necessarily figure that out.

Fixes part of #27772.

ea5792f333 Make crypto_strongest_rand() non-mockable
Instead, have it call a mockable function.  We don't want
crypto_strongest_rand() to be mockable, since doing so creates a
type error when we call it from ed25519-donna, which we do not build
in a test mode.

Travis: use the Homebrew addon
Use the Travis Homebrew addon to install packages on macOS. The package
list is the same, but the Homebrew addon does not do a `brew update` by
default.

This makes builds faster, at the cost of using slightly older packages.

ChangeLog: delete both consensus flavours to un-break nss
The required protocol version check occurs before the consensus flavour
check. So on directory mirrors (and some client configs), alpha users need
to delete both consensus flavours to workaround nss bugs.
