This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.
Git blame's --ignore-rev flag can be used to ignore this commit when
attempting to `git blame` some code.
Step 1 of removing abseil from lokinet.
For the most part this is a drop-in replacement, but there are also a
few changes here to the JSONRPC layer that were needed to work around
current gcc 10 dev snapshot:
- JSONRPC returns a json now instead of an optional<json>. It doesn't
make any sense to have a json rpc call that just closes the connection
with returning anything. Invoked functions can return a null (default
constructed) result now if they don't have anything to return (such a
null value won't be added as "result").
Success case:
- the path endpoint creates and sends a LR_StatusMessage upon
successful path creation
Failure case:
- an intermediate hop creates and sends a LR_StatusMessage upon
failure to forward the path to the next hop for any reason
Both cases:
- transit hops receive LR_StatusMessages and add a frame
to them reflecting their "status" with respect to that path
- the path creator receives LR_StatusMessages and decrypts/parses
the LR_StatusRecord frames from the path hops. If all is good,
the Path does as it would when receiving a PathConfirmMessage.
If not, the Path marks the new path as failed.
LR_StatusMessage is now used/sent in place of PathConfirmMessage
