None of the relay users require the use of mutable structs for callbacks,
however the relay code does. Instead of assigning the default callback
for subbuf_start, add a wrapper to conditionally call the client callback
if available, and fall back to default behaviour otherwise.
This lets all relay users make their struct rchan_callbacks const data.
