653c6d129e Make consensus diff sha3 operations mockable.

6a36e5ff3b String-based API for consensus diffs.
Also, add very strict split/join functions, and totally forbid
nonempty files that end with somethig besides a newline.  This
change is necessary to ensure that diff/apply are actually reliable
inverse operations.

3647751c2a prop140: Use sha3-256, not sha2-256
This is a protocol update from recent prop140 changes.

Also, per #21673, we need to check the entire document, including
signatures.

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.

Reset buf after each succesful test to avoid artifacts.
This patch resets `buf` in test_util_fgets_eagain() after each succesful
ivocation to avoid stray artifacts left in the buffer by erroneous
tor_fgets() calls.

Use tor_fgets() instead of fgets().
This patch changes our use of fgets() to tor_fgets() for more consistent
error handling across different versions of the C library.

498287b3c3
Add compatibility function for fgets(3).
This patch adds the `tor_fgets()` function to our compatibility layer.

`tor_fgets()` adds an additional check for whether the error-bit have
been enabled for the given file stream, if that is the case and `errno`
is set to `EAGAIN` we make sure that we always return NULL.

Unfortunately `fgets(3)` behaves differently on different versions of
the C library.

5298ab5917 Restore correct behavior of 0.3.0.4-rc with bridges+ipv6-min
In that chutney test, the bridge client is configured to connect to
the same bridge at 127.0.0.1:5003 _and_ at [::1]:5003, with no
change in transports.

That meant, I think, that the descriptor is only assigned to the
first bridge when it arrives, and never the second.

18a98206ed Improve descriptor checks in the new guard algorithm.
- Make sure we check at least two guards for descriptor before making
  circuits. We typically use the first primary guard for circuits, but
  it can also happen that we use the second primary guard (e.g. if we
  pick our first primary guard as an exit), so we should make sure we
  have descriptors for both of them.

- Remove BUG() from the guard_has_descriptor() check since we now know
  that this can happen in rare but legitimate situations as well, and we
  should just move to the next guard in that case.
