- New package `perform` which contains all `Perform` functions
- New package `helpers` which contains helper functions used by both
perform and query/input functions.
- Perform invite/leave have no idea how to `WriteOutputEvents` and this
is now returned from `PerformInvite` or `PerformLeave` respectively.
Still to do:
- RSAPI is fed into the inviter/joiner/leaver - this introduces circular
logic so will need to be removed.
- Put query operations in a `query` package.
- Put input operations (and output) in an `input` package.
- Factor out helper functions as much as possible, possibly rejigging the
storage layer in the process.
* Make PerformJoin send input membership event
* Invite input room events in separate goroutine
* Don't limit roomserver input events using request context
* Synchronous input room events
* Nope, that didn't work
* oops send state key to GetMembership
* Don't generate stripped state in client API more times than necessary, generate output events on receiving end of federated invite
* Commit membership updater changes
* Tweaks
* Add PerformInvite and refactor how errors get handled
- Rename `JoinError` to `PerformError`
- Remove `error` from the API function signature entirely. This forces
errors to be bundled into `PerformError` which makes it easier for callers
to detect and handle errors. On network errors, HTTP clients will make a
`PerformError`.
* Unbreak everything; thanks Go!
* Send back JSONResponse according to the PerformError
* Update federation invite code too
