78cbced45c Rename "tell_event_loop_to_finish" to "...run_external_code"
This function was never about 'finishing' the event loop, but rather
about making sure that the code outside the event loop would be run
at least once.

cf75c1af66 hs-v3: Don't fetch descriptor if we have a pending request
If 6 SOCKS requests are opened at once, it would have triggered 6 fetches
which ultimately poke all 6 HSDir. We don't want that, if we have multiple
SOCKS requests for the same service, do one fetch only.

66aff2d8f3 Remove or_circuit_t.is_first_hop; use channel_is_client() instead
The is_first_hop field should have been called used_create_fast,
but everywhere that we wanted to check it, we should have been
checking channel_is_client() instead.

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.

Here's the perl I used to do this:

\#!/usr/bin/perl -w -i -p

s/read_to_buf\(/buf_read_from_socket\(/;
s/flush_buf\(/buf_flush_to_socket\(/;

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
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.

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.

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.

0b2018a4d0 Refactor legacy code to support hs_ident along with rend_data.
The legacy HS circuit code uses rend_data to match between circuits and
streams. We refactor some of that code so that it understands hs_ident
as well which is used for prop224.

79b59a2dfc TROVE-2017-004: Fix assertion failure in relay_send_end_cell_from_edge_
This fixes an assertion failure in relay_send_end_cell_from_edge_() when an
origin circuit and a cpath_layer = NULL were passed.

A service rendezvous circuit could do such a thing when a malformed BEGIN cell
is received but shouldn't in the first place because the service needs to send
an END cell on the circuit for which it can not do without a cpath_layer.

Fixes #22493
