Docs: make prose discussion match the ordering of Table 9-58.

The "Session Information Functions" table seems to be sorted mostly
alphabetically (although it's not perfect), which would be all right
if it didn't lead to some related functions being described in a
pretty nonintuitive order.  Also, the prose discussions after the table
were in an order that hardly matched the table at all.  Rearrange to
make things a bit easier to follow.
