9c2bc441f8 If out-of-disk when saving a consensus cache entry, don't BUG. 
Just warn instead.

0dbe3ddc33 Make Tor support TLS1.3 ciphers with OpenSSL 1.1.1 
Without this patch, not only will TLS1.3 not work with Tor, but
OpenSSL 1.1.1 with TLS1.3 enabled won't build any connections at
all: It requires that either TLS1.3 be disabled, or some TLS1.3
ciphersuites be listed.

Closes ticket 24978.

a15eb9ff43 MAX_REND_FAILURES is 1, but we would try three times 
Fix an "off by 2" error in counting rendezvous failures on the onion
service side.

While we thought we would stop the rendezvous attempt after one failed
circuit, we were actually making three circuit attempts before giving up.

af8cadf3a9 Remove false positives from channel_is_client() 
Fix a set of false positives where relays would consider connections
to other relays as being client-only connections (and thus e.g.
deserving different link padding schemes) if those relays fell out
of the consensus briefly.

Now we look only at the initial handshake and whether the connection
authenticated as a relay.

Clear the address when we can't choose a reachable address

return value.

520cf21793 Move destroy cells into a separate queue type of their own, to save RAM 
We've been seeing problems with destroy cells queues taking up a
huge amount of RAM.  We can mitigate this, since while a full packed
destroy cell takes 514 bytes, we only need 5 bytes to remember a
circuit ID and a reason.

Fixes bug 24666. Bugfix on 0.2.5.1-alpha, when destroy cell queues
were introduced.

6ab07419c8 Use local descriptor object to exclude self in path selection 
TROVE-2017-12. Severity: Medium

When choosing a random node for a circuit, directly use our router
descriptor to exclude ourself instead of the one in the global
descriptor list. That list could be empty because tor could be
downloading them which could lead to not excluding ourself.

3030741b5d hs-v2: Remove any expiring intro from the retry list 
TROVE-2017-13. Severity: High.

In the unlikely case that a hidden service could be missing intro circuit(s),
that it didn't have enough directory information to open new circuits and that
an intro point was about to expire, a use-after-free is possible because of
the intro point object being both in the retry list and expiring list at the
same time.

The intro object would get freed after the circuit failed to open and then
access a second time when cleaned up from the expiring list.

3bb29dd707 Correctly handle partial success in consensus diff calculation. 
Previously, if store_multiple() reported a partial success, we would

possible for the diff to be only partially successful -- for
example, if LZMA failed but the other compressors succeeded.
