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 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.
This patch moves the logic that adds the proxy headers to an earlier
point in the exit connection lifetime, which ensures that the
application data cannot be written to the outbuf before the proxy header
is added.

This patch changes HiddenServiceExportCircuitID so instead of being a
boolean it takes a string, which is the protocol. Currently only the
'haproxy' protocol is defined.

Without this patch we would encode the IPv6 address' last part as
::ffffffff instead of ::ffff:ffff when the GID is UINT32_MAX.
