These are both warnings about the trivial constructors,

which are always followed by a ::decode. We don't initialize fields in
any of these so we probably have these coverity warnings for every
message. Perhaps we should add some annotations to indicate that? Danny,
are you familiar with those?
(I don't think we want to initialize... unless we rely on the optimizer to
do magic it's inefficient to initialize the value and then overwrite it
during decode shortly after.)
