f75325c132 No spaces around = in variable assignment
BSD make takes spaces around = literally

e033d5e90b Ignore accept6/reject6 IPv4, warn about unexpected rule outcomes
When parsing torrc ExitPolicies, we now warn if:
  * an IPv4 address is used on an accept6 or reject6 line. The line is
    ignored, but the rest of the policy items in the list are used.
    (accept/reject continue to allow both IPv4 and IPv6 addresses in torrcs.)
  * a "private" address alias is used on an accept6 or reject6 line.
    The line filters both IPv4 and IPv6 private addresses, disregarding
    the 6 in accept6/reject6.

When parsing torrc ExitPolicies, we now issue an info-level message:
  * when expanding an accept/reject * line to include both IPv4 and IPv6
    wildcard addresses.

In each instance, usage advice is provided to avoid the message.

8b98172579 Add a rend cache failure info dup function
When validating a new descriptor against our rend cache failure, we were
added the failure entry to the new cache entry without duplicating. It was
then freed just after the validation ending up in a very bad memory state
that was making tor abort(). To fix this, a dup function has been added and
used just before adding the failure entry.

07b3028db7 Prohibit the use of one entry node with an HS
In a nutshell, since a circuit can not exit at its entry point, it's very
easy for an attacker to find the hidden service guard if only one EntryNodes
is specified since for that guard, the HS will refuse to build a rendezvous
circuit to it.

For now, the best solution is to stop tor to allow a single EntryNodes for
an hidden service.

bab221f113 Refactor our logic for sending events to controllers
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:

  1) Calling the network stack directly here would make a huge portion
     of our networking code (from which so much of the rest of Tor is
     reachable) reachable from everything that potentially generated
     controller events.

  2) Since _some_ events (EVENT_ERR for instance) would cause us to
     call connection_flush(), every control_event_* function would
     appear to be able to reach even _more_ of the network stack in
     our cllgraph.

  3) Every time we generated an event, we'd have to walk the whole
     connection list, which isn't exactly fast.

This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.

* FIXES #16823: https://bugs.torproject.org/16823
   If an OP were to send a CREATE_FAST cell to an OR, and that

   be called on the create cell twice.  This fix removes the second
   (conditional on the key material being bad) call to tor_free(), so
   that now the create cell is always freed once, regardless of the status of
   the key material.

   (This isn't actually a double-free bug, since tor_free() sets its
   input to NULL, and has no effect when called with input NULL.)
