After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.

This likely affected bridge clients with IPv6 bridges.

Resolves #18921.

Also, document the actual behavior and return values of
tor_terminate_process.

Fixes bug18686; bugfix on 0.2.3.9-alpha.

The problem is that "q" is always set on the first iteration even
if the question is not a supported question. This set of "q" is
not necessary, and will be handled after exiting the loop if there
if a supported q->type was found.

 * SHA-3/SHAKE use little endian for certain things, so byteswap as
   needed.

 * The code was written under the assumption that unaligned access to
   quadwords is allowed, which isn't true particularly on non-Intel.

Fix #18240.  This version of the bug first appeared in
0.2.8.2-alpha.  0.2.8.1-alpha and earlier had a different bug.

Based on a patch from cypherpunks.

addresssanitizer likes to put backtraces on stderr.

As well as the existing reports of IPv6 address additions or removals,
the script now warns when keys change but IPv4:ORPort or
IPv6:IPv6ORPort remain the same.

Existing checks for other whitelist detail changes have also
been re-worded and upgraded to warnings.

This makes it easier for changes to be identified so operators can
be contacted to confirm whether the change is stable.

Also add misbehaving relays to updateFallbackDirs.py blacklist,
but leave them commented out in case it's a transient issue,
or it's been resolved by the download check fixes. (These
relays hang stem's downloader. It's unlikely they'll ever help
clients.)

Apparently somewhere along the line we decided that MIN might be
missing.

But we already defined it (if it was missing) in compat.h, which
everybody includes.

Closes ticket 18889.

Remove trunnel files from libor/libcrypto, since they are in libtrunnel. Found with modularity tool.

When we connect to a hidden service as a client we may need three internal
circuits, one for the descriptor retrieval, introduction, and rendezvous.
Let's try to make sure we have them. Closes #13239.

This abstraction covers the case where one part of the program needs
to refer to another object that is allowed to disappear.

Use IP address, effective family, and contact info to
discover and limit fallbacks to one per operator.

Also analyse netblock, ports, IP version, and Exit flag,
and print the results. Don't exclude any fallbacks from
the list because of netblocks, ports, IP version, or
Exit flag.
