Separate backend_send from backend_sendbuffer.

Browse Source 
On a similar theme of separating the query operation from the
attempted change, backend_send() now no longer has the side effect of
returning the current size of the send buffer. Instead, you have to
call backend_sendbuffer() every time you want to know that.
