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.

1582adabbb Change approach to preventing duplicate guards.
Previously I'd made a bad assumption in the implementation of
prop271 in 0.3.0.1-alpha: I'd assumed that there couldn't be two
guards with the same identity.  That's true for non-bridges, but in
the bridge case, we allow two bridges to have the same ID if they
have different addr:port combinations -- in order to have the same
bridge ID running multiple PTs.

Fortunately, this assumption wasn't deeply ingrained: we stop
enforcing the "one guard per ID" rule in the bridge case, and
instead enforce "one guard per <id,addr,port>".

We also needed to tweak our implementation of
get_bridge_info_for_guard, since it made the same incorrect
assumption.

Fixes bug 21027; bugfix on 0.3.0.1-alpha.

b923c4dc9f Code to disable memory sentinels for fuzzing
This feature makes it possible to turn off memory sentinels (like
those used for safety in buffers.c and memarea.c) when fuzzing, so
that we can catch bugs that they would otherwise prevent.

f6e5a658df Revise the logic for picking the start time for link certs
Since 0.2.4.11-alpha (in 0196647970) we've tried to randomize
the start time to up to some time in the past.  But unfortunately we
allowed the start time to be in the future as well, which isn't
really legit.

The new behavior lets the start time be be up to
MAX(cert_lifetime-2days, 0) in the past, but never in the future.

4ed10e5053 hs: Fix bad use of sizeof() when encoding ESTABLISH_INTRO legacy cell
When encoding a legacy ESTABLISH_INTRO cell, we were using the sizeof() on a
pointer instead of using the real size of the destination buffer leading to an
overflow passing an enormous value to the signing digest function.
Fortunately, that value was only used to make sure the destination buffer
length was big enough for the key size and in this case it always was because
of the overflow.

Fixes #21553
