Convert macros to static inline functions (bufpage.h)
Remove PageIsValid() and PageSizeIsValid(), which weren't used and seem unnecessary. Some code using these formerly-macros needs some adjustments because it was previously playing loose with the Page vs. PageHeader types, which is no longer possible with the functions instead of macros.
