5766eed38f Fixes when applying diffs: Allow 2-line diffs, fix bogus free
The 2-line diff changs is needed to make the unit tests actually
test the cases that they thought they were testing.

The bogus free was found while testing those cases

360d043ac7 Use "STATIC" to export consdiff fns for testing
Previously test_consdiff.c just did #include "consdiff.c", which is
not great style, and messes up coverage testing.

44514058b9 Correctly handle fd-drain errors on windows workqueues
Windows doesn't let you check the socket error for a socket with
WSAGetLastError() and getsockopt(SO_ERROR).  But
getsockopt(SO_ERROR) clears the error on the socket, so you can't
call it more than once per error.

When we introduced recv_ni to help drain alert sockets, back in
0.2.6.3-alpha, we had the failure path for recv_ni call getsockopt()
twice, though: once to check for EINTR and one to check for EAGAIN.
Of course, we never got the eagain, so we treated it as an error,
and warned about: "No error".

The fix here is to have these functions return -errno on failure.

Fixes bug 21540; bugfix on 0.2.6.3-alpha.

9014dc111a Improve keccak-tiny performance by 15% on LE intel
The 64-bit load and store code was generating pretty bad output with
my compiler, so I extracted the code from csiphash and used that instead.

dc37ea8b98 Add a null statement to prevent some SMARTLIST_FOREACH() bugs.
So we require that SMARTLIST_FOREACH_END() have the name of the loop
variable in it.  But right now the only enforcement for that is to
clear the variable at the end of the loop, which is really not
sufficient: I spent 45 minutes earlier today debugging an issue
where I had said:
   SMARTLIST_FOREACH_BEGIN(spool, spooled_resource_t *, spooled) {
     ...
   } SMARTLIST_FOREACH_END(spool);

This patch makes it so that ONLY loop variables can be used, by
referring to the _sl_idx variable.

Make MAX_DIR_PERIOD independent of MIN_ONION_KEY_LIFETIME.
As part of the work for proposal #274 we are going to remove the need

6cab0f8ad7 Fix failing bridges+ipv6-min integration test.
The bridges+ipv6-min integration test has a client with bridges:
    Bridge 127.0.0.1:5003
    Bridge [::1]:5003
which got stuck in guard_selection_have_enough_dir_info_to_build_circuits()
because it couldn't find the descriptor of both bridges.

Specifically, the guard_has_descriptor() function could not find the
node_t of the [::1] bridge, because the [::1] bridge had no identity
digest assigned to it.

After further examination, it seems that during fetching the descriptor
for our bridges, we used the CERTS cell to fill the identity digest of
127.0.0.1:5003 properly. However, when we received a CERTS cell from
[::1]:5003 we actually ignored its identity digest because the
learned_router_identity() function was using
get_configured_bridge_by_addr_port_digest() which was returning the
127.0.0.1 bridge instead of the [::1] bridge (because it prioritizes
digest matching over addrport matching).

The fix replaces get_configured_bridge_by_addr_port_digest() with the
recent get_configured_bridge_by_exact_addr_port_digest() function. It
also relaxes the constraints of the
get_configured_bridge_by_exact_addr_port_digest() function by making it
return bridges whose identity digest is not yet known.

By using the _exact_() function, learned_router_identity() actually
fills in the identity digest of the [::1] bridge, which then allows
guard_has_descriptor() to find the right node_t and verify that the
descriptor is there.

FWIW, in the bridges+ipv6-min test both 127.0.0.1 and [::1] bridges
correspond to the same node_t, which I guess makes sense given that it's
actually the same underlying bridge.
