The current approach of running solana checks in Tilt is a bit unwieldy
and makes it hard to find errors in all the log spam. Move the checks
into a github action instead. This gives us more flexibility to add
formatting and linting checks and also makes it easier to quickly find
any issues in the logs.
When processing pending observations, the `handleCleanup` function
checks if we already have a stored quorum VAA and deletes the in-memory
observation if one is found. If a stored quorum VAA is not found, then
we're supposed to continue evaluating the other conditions and take
the appropriate action. This was implemented using a `fallthrough`
statement.
Unfortunately, this is not how `fallthrough` works. `fallthrough`
simply tells the compiler to execute the body of the next branch in
the switch block, *without evaluating the condition*. It also doesn't
evaluate the conditions for any of the other branches in the switch.
In practice what this meant is that for local observations that didn't
have quorum we would always take the first branch, fall through to the
second branch, and then exit the switch. Only once we had a quorum
(`s.submitted == true`) would we actually consider any of the other
branches in the switch. It also meant that there was no case where we
would take the branch for re-observing messages that hadn't reached
quorum.
Fix this by moving the stored quorum VAA check into an if statement and
then falling through to the switch statement if one is not found.
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).
