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.

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.
Part of #27410.

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.

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.
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.
Fixes bug 27728; bugfix on 0.3.5.1-alpha
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.
Implements ticket 27738.
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.
Closes ticket 27756.
Since the default cache directory is the same as the default data
directory, we don't want the default CacheDirectoryGroupReadable
value (0) to override an explicitly set "DataDirectoryGroupReadable
1".
To fix this, I'm making CacheDirectoryGroupReadable into an
autobool, and having the default (auto) value mean "Use the value of
DataDirectoryGroupReadable if the directories are the same, and 0
otherwise."
Fixes bug 26913; bugfix on 0.3.3.1-alpha when the CacheDirectory
option was introduced.
This shouldn't be a user-visible change: nobody has a 16 MB RSA
key that they're trying to use with Tor.
I'm doing this to fix CID 1439330 / ticket 27730, where coverity
complains (on 64-bit) that we are making a comparison that is never
true.
