encoding/json walked every payload on every call. ZAP reads a field at a
constant offset out of the buffer that arrived, and //tools/zap has
already stated those offsets for every payload, so the transport now asks
the payload for its own bytes and the parse step is gone.
The envelope collapses with it. clientCall and serverCall existed only
because JSON needed one type to hold an any and another to hold a
RawMessage; bytes are bytes, so one Call serves both ends. Framing comes
from the ZAP header, which declares its own length.
A payload that is nothing -- the *struct{} a method takes when it has no
argument or no result -- carries nothing. Anything else without a layout
fails the call naming the type, so a payload that would have arrived
silently empty does not arrive at all.
The methods that took a bare string or returned a bare int now take and
return named payloads, because a scalar has no layout to state and the
rest of the API was already shaped this way.
