We use lambda callbacks as the main way to interface with the `send` and
`recv` functions at the core of the RPC interface. This provided the
user with a pointer to the underlying data buffer to use. However, this
was somewhat annoying to use as it required constant bit casts. This
patch uses template magic to infer the desired type and automatically
cast to what the user passes in. Some static checks ensure that this is
actually legal. This will allow for functions to more easily describe
structs that match the expected argument format.
