Also improve the unittest to make sure it catches the right error.

5d89ea1e6c prop224: Decouple the HS part of connection_ap_handshake_rewrite_and_attach().
We will need to edit this function, and it's already pretty huge. Let's make
it a bit smaller.

This commit moves code, fixes a 80 char line and add two lines at the start to
make it compile. Trivial change.

bce18a7642 prop224: Refactor parse_extended_hostname() to parse v3 addrs.
We need this func so that we recognize SOCKS conns to v3 addresses.

- Also rename rend_valid_service_id() to rend_valid_v2_service_id()

- Also move parse_extended_hostname() tests to their own unittest, and
  add a v3 address to the test as well.

3e593f09ad prop224: Recompute all HSDir indices when we enter overlap mode.
When we enter overlap mode we start using the next hsdir index of
relays. However, we only compute the next hsdir index of relays when we
receive a consensus or their descriptor. This means that there is a
window of time between entering the overlap period and fetching the
consensus where relays have their next hsdir index uninitialized. This
patch fixes this by recomputing all hsdir indices when we first enter
the overlap period.

7823c98a38 prop224: Improve descriptor reupload logic.
We want to reupload our descriptor if its set of responsible HSDirs
changed to minimize reachability issues.

This patch adds a callback everytime we get new dirinfo which checks if
the hash ring changed and reuploads descriptor if needed.

1f7b8012ae prop224: Only upload descriptor if we have good hash ring and SRV.
Make sure we have a live consensus (for SRV) and enough descriptors (for
hash ring).

Also fix unittests that broke.

97347b1109 Fuzz outer layer of hsv3 descriptor
The code in fuzz_hsdescv3.c fuzzes the unencrypted layer of the hsv3
descriptor. We need to fuzz the encrypted layer later.

257f50b22f Make Windows happy for time_t printf format
Our Windows compiler treats "time_t" as long long int but Linux likes it
long int so cast those to make Windows happy.

This change should improve overhead for downloading small numbers of
descriptors and microdescriptors by improving compression
performance and lowering directory request overhead.
