Instead of using a numberOfRequiredKeys count to distinguish required

and non-required keys in a btree index scan, mark the required scankeys
with private flag bits SK_BT_REQFWD and/or SK_BT_REQBKWD.  This seems
at least marginally clearer to me, and it eliminates a wired-into-the-
data-structure assumption that required keys are consecutive.  Even though
that assumption will remain true for the foreseeable future, having it
in there makes the code seem more complex than necessary.
