shouldn't XFoo implementations use sal_Bool, and not bool?

The functions are apparently copied from XResultSet (incl. presumably 
unnecessary virtual and SAL_CALL, even), but technically they are 
unrelated.  That means there is no technical reason to make them use the 
inferior sal_Bool instead of bool (and loplugin:salbool should warn 
about such unnecessary uses of sal_Bool).
