def96ce838 sendme: Fix coverity CID 1444999 
The code flow in theory can end up with a layer_hint to be NULL but in
practice it should never happen because with an origin circuit, we must have
the layer_hint.

Just in case, BUG() on it if we ever end up in this situation and recover by
closing the circuit.

Fixes #30467.

07e4b09b5f sendme: Add FlowCtrl protover value 
See proposal 289 section 4.3 for more details.

It describes the flow control protocol at the circuit and stream level. If
there is no FlowCtrl protocol version, tor supports the unauthenticated flow
control features from its supported Relay protocols.

At this commit, relay will start advertising FlowCtrl=1 meaning they support
authenticated SENDMEs v1.

Closes #30363

0ed5c6edf9 Hiding crypt_path_t: Move some more crypt_path-specific functions. 
- Move test-only cpath_get_n_hops() to crypt_path.c.
- Move onion_next_hop_in_cpath() and rename to cpath_get_next_non_open_hop().

The latter function was directly accessing cpath->state, and it's a first step
at hiding ->state.

58fbbc1409 Hiding crypt_path_t: Rename some functions to fit the crypt_path API. 
Some of these functions are now public and cpath-specific so their name should
signify the fact they are part of the cpath module:

assert_cpath_layer_ok -> cpath_assert_layer_ok
assert_cpath_ok -> cpath_assert_ok
onion_append_hop -> cpath_append_hop
circuit_init_cpath_crypto -> cpath_init_circuit_crypto
circuit_free_cpath_node -> cpath_free
onion_append_to_cpath -> cpath_extend_linked_list

cd38e41620 Hiding crypt_path_t: Ensure that ->private is initialized. 
Now that we are using a constructor we should be more careful that we are
always using the constructor to initialize crypt_path_t, so make sure that
->private is initialized.

f5635989b0 Hiding crypt_path_t: Create a constructor for crypt_path_t. 
We are using an opaque pointer so the structure needs to be allocated on the
heap. This means we now need a constructor for crypt_path_t.

Also modify all places initializing a crypt_path_t to use the constructor.

6f42efaa59 Move voteflags.[ch] to become dirauth only. 
For various reasons, this was a nontrivial movement.  There are
several places in the code where we do something like "update the
flags on this routerstatus or node if we're an authority", and at
least one where we pretended to be an authority when we weren't.
