The wormhole sdk is a new go module in the sdk/ directory. This
initially contains the *_consts.go files from the common package in the
top-level sdk package and the entire vaa package as a sub-package.
For go reasons this needs to be in the sdk directory itself (rather than
a sdk/go subdir). To prevent the go tooling from looking into the other
non-go subdirs, add an empty go.mod file in each one. See
golang issue 42965 for more details on why we can't have nice
things (I'm deliberately not linking to stop github from spamming that
issue).
Currently if an observation hasn't reached quorum within 5 minutes, the
processor will re-broadcast the signed local observation to the other
guardians in the network. However if not enough guardians actually
observed the original tx, then no amount of re-broadcasting will help
the network reach quorum.
Fix this issue by sending a re-observation request whenever we
re-broadcast a signed local observation. This ensures that any
guardians that missed the tx the first time it happened have a chance to
re-observe it and help the network reach quorum.
We need to reuse almost all of the gossip infrastructure for accounting
transactions, with the only difference being that accounting will use a
`Transfer` message rather than a `VAA`.
Make the observation stored in the processor state generic so that it
can be either a VAA or a Transfer. The rest of the code is shared.
This allows us to associate an observation from the log
for messages that the local node did not observe.

Optional metadata for debugging. Allows tying a received observation
to an on-chain transaction even if the node missed the observation.
