Continuing rework for async RPC.
Now NFS server functions are responsible for sending a reply to the client
instead of returning a result to the RPC dispatch routine. This will
allows the server functions to handle memory cleanup (instead of requiring
static data) and allows returns to be decoupled in time from when the
request arrives.
There is still some static data to clean up, but this moves us much closer
to allowing multiple requests in progress at once.

can eventually support multi-threaded and asynchronous handling of
