Thomas Munro 2f27f8c511 Provide ReadRecentBuffer() to re-pin buffers by ID. 
If you know the ID of a buffer that recently held a block that you would
like to pin, this function can be used check if it's still there.  It
can be used to avoid a second lookup in the buffer mapping table after
PrefetchBuffer() reports a cache hit.
