Host not connected, host shutting down and instance not running are
now UnavailableError (503) instead of ConflictError. The request error
migration notes move to a new 2.1 guide, since this ships in 2.1.

Error responses now carry the registered name of the thrown error's
class, and the requester rejects with an instance of that class instead
of a generic RequestError. Error classes are registered like message
classes, and plugins list their own in `errors`.
RequestError is replaced by a hierarchy following the HTTP status codes:
ClientError (ValidationError, ForbiddenError, NotFoundError,
TimeoutError, ConflictError) and ServerError (InternalServerError).
PermissionError is PermissionDeniedError and the config errors
InvalidValue, InvalidField and InvalidAccess gain an Error suffix.
Link logs only errors whose class is not registered. These arrive on the
other side as InternalServerError with the original message and stack,
so an error forwarded through the controller is logged once, where it
was thrown.

Generic error handlers such as FactorioServer.handle() and the event
handler catch in Link only log err.stack, so the ajv errors attached to
an InvalidMessage were lost unless the catch site checked for the class
explicitly. Appending the errors to the stack in the constructor makes
every stack-logging handler show which field failed validation without
special casing each one.

The lib library was written with the assumption that there's only one
copy of it in the whole application and everything imports that one
copy. Unfortunately there are quite a few circumstances were package
managers end up installing multiple copies of lib and then different
parts use different versions of the library.
This causes Clusterio to break with strange and hard to track down
errors. Most notably permissions and link messages for a plugin may get
registered to one copy of lib while the controller uses a different copy
and thus does not see or register that what the plugin added exists.
Detect this condition when importing @clusterio/lib and throw an error
when it has been imported twice in order to prevent the broken
installation from causing future hard to debug issues.
