CreatePrivateZone carries editMode as one more byte, written only when set, so
a plain private zone is sent as before. Master keeps it on the instance, starts
the world server with -editmode 1, and gives a private instance's replacement
(a reload or a live update) the same flag. Nothing sets it yet.
A capped string now skips the characters it cut, so what follows it is read
from the right place. A request to join a private instance that is still
starting is answered once its world server is ready, instead of at once with
an address nothing listens on yet.
