New version of the patch. As Andrzej has pointed out, db.max.outlinks.per.page
is read once per getRecordWriter now.

This patch doesn't change how parse data reads outlinks. Before this patch,
parse data used to read db.max.outlinks.per.page outlinks then skip over (as in
read the outlink then ignore it) the rest. After this patch, parse data reads
all outlinks. So, I/O behaviour is the same.
