This replaces all use of std::optional's `opt.value()` with `*opt`
because macOS is great and the ghost of Steve Jobs says that actually
supporting std::optional's value() method is not for chumps before macOS
10.14. So don't use it because Apple is great.
Pretty much all of our use of it actually is done better with operator*
anyway (since operator* doesn't do a check that the optional has a
value).
Also replaced *most* of the `has_value()` calls with direct bool
context, except for one in the config section which looked really
confusing at a glance without a has_value().
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

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
