Allow pg_rewind to use a standby server as the source system.
Using a hot standby server as the source has not been possible, because
pg_rewind creates a temporary table in the source system, to hold the
list of file ranges that need to be fetched. Refactor it to queue up the
file fetch requests in pg_rewind's memory, so that the temporary table
is no longer needed.
Also update the logic to compute 'minRecoveryPoint' correctly, when the
source is a standby server.
