Rationalize GetWalRcv{Write,Flush}RecPtr().
GetWalRcvWriteRecPtr() previously reported the latest *flushed*
location. Adopt the conventional terminology used elsewhere in the tree
by renaming it to GetWalRcvFlushRecPtr(), and likewise for some related
variables that used the term "received".
Add a new definition of GetWalRcvWriteRecPtr(), which returns the latest
*written* value. This will allow later patches to use the value for
non-data-integrity purposes, without having to wait for the flush
pointer to advance.
