Heikki Linnakangas d6ec0456e8 Add 'neon_seqscan_rel' test function, to test sequential scan performance. ...

Usage:

    postgres=# \timing
    Timing is on.
    postgres=# select neon_seqscan_rel('pgbench_accounts', 1000);
    INFO:  scanning 491804 blocks, prefetch 1000
    INFO:  blk 0/491804
    INFO:  blk 1024/491804
    INFO:  blk 2048/491804
    INFO:  blk 3072/491804
    ...
    INFO:  blk 489472/491804

The second argument to the function is the number of pages to prefetch.
Note: the prefetching in this function works differently from the
prefetching we have for sequential scans in 'main'. After receiving the
result for a block, it immediately sends the request for the next page,
it doesn't send them in batches like 'main' does.
