e07e95edd3 Bug 25903: Perform accounting for new CIRC_BW fields.
Two new values in each direction. DELIVERED counts valid end-to-end circuit
data that is accepted by our end and OVERHEAD counts the slack unused data in
each of the relay command cells for those accepted cells.

Control port changes are in the next commit.

* ADD new /src/common/crypto_rand.[ch] module.
 * ADD new /src/common/crypto_util.[ch] module (contains the memwipe()
   function, since all crypto_* modules need this).

5dbcd48f0e hs-v3: Attempt descriptor refetch when dirinfo changes
When the directory information changes, callback to the HS client subsystem so
it can check if any pending SOCKS connections are waiting for a descriptor. If
yes, attempt a refetch for those.

cf75c1af66 hs-v3: Don't fetch descriptor if we have a pending request

4a7e90adc5 Repair buffer API so everything starts with buf_.
Our convention is that functions which manipulate a type T should be
named T_foo.  But the buffer functions were super old, and followed
all kinds of conventions.  Now they're uniform.

80d3887360 Refactor node lookup APIs to take flags
Right now there's a single warn_if_unnamed flag for
router_get_consensus_status_by_nickname() and
node_get_by_nickname(), that is nearly always 1.  I've turned it
into an 'unsigned' bitfield, and inverted its sense.  I've added the
flags argument to node_get_by_hex_id() too, though it does nothing
there right now.

I've removed the router_get_consensus_status_by_nickname() function,
since it was only used in once place.

This patch changes the warning behavior of GETINFO ns/name/<name>,
since all other name lookups from the controller currently warn.

Later I'm going to add more flags, for ed25519 support.

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

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

We need this func so that we recognize SOCKS conns to v3 addresses.

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

30b5c6a95e prop224: Link rendezvous circuit to edge connection
This commit refactors the handle_hs_exit_conn() function introduced at a prior
commit that connects the rendezvous circuit to the edge connection used to
connect to the service virtual port requested in a BEGIN cell.

The refactor adds the support for prop224 adding the
hs_service_set_conn_addr_port() function that has the same purpose has
rend_service_set_connection_addr_port() from the legacy code.

The rend_service_set_connection_addr_port() has also been a bit refactored so
the common code can be shared between the two HS subsystems (legacy and
prop224).

In terms of functionallity, nothing has changed, we still close the circuits
in case of failure for the same reasons as the legacy system currently does.

7163ce7f62 hs: Refactor the service exit connection code
This commit simply moves the code from the if condition of a rendezvous
circuit to a function to handle such a connection. No code was modified
_except_ the use or rh.stream_id changed to n_stream->stream_id so we don't
have to pass the cell header to the function.

This is groundwork for prop224 support which will break down the
handle_hs_exit_conn() depending on the version of hidden service the circuit
and edge connection is for.
