Lots of code was using 32-byte nonces for xchacha20 symmetric
encryption, but this just means 8 extra bytes per packet wasted as
chacha is only using the first 24 bytes of that nonce anyway.
Changing this resulted in a lot of dead/dying code breaking, so this
commit also removes a lot of that (and comments a couple places with
TODO instead)
Also nounce -> nonce where it came up.
change path control message inner message response to take just a
string, which will be a bt-encoded response with an early key for
status. If there is a timeout we pass a bt dict that only has that as
the status, else the response we de-onioned should have either an OK
status or some other error.
change messages to use new status key
correctly call Path::EnterState on path build response
- control messages can be sent along a path
- the path owner onion-encrypts the "inner" message for each hop in the
path
- relays on the path will onion the payload in both directions, such
that the terminal relay will get the plaintext "inner" message and the
client will get the plaintext "response" to that.
- control messages have (mostly, see below) been changed to be invokable
either over a path or directly to a relay, as appropriate.
TODO:
- exit messages need looked at, so they have not yet been changed for
this
- path transfer messages (traffic from client to client over 2 paths
with a shared "pivot") are not yet implemented
- includes are now sorted in consistent, logical order; first step in an attempt to fix the tomfoolery (no relation to Tom) brought in by include-what-you-use
- shuffled around some cmake linking to simplify dependency graph
- superfluous files removed
- almost all errors have been commented out for refactor or already refactored
- committing this prior to sorting out the cmake structure
- upcoming include-what-you-use application
