912c11761c prop224: Move some rendclient.c code to hs_common.c
Specifically move the pick_hsdir() function and all the HSDir request tracking
code. We plan to use all that code both for v2 and v3.

This commit only moves code.

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.
