Cleanup: Make InnoDB page numbers uint32_t
InnoDB stores a 32-bit page number in page headers and in some
data structures, such as FIL_ADDR (consisting of a 32-bit page number
and a 16-bit byte offset within a page). For better compile-time
error detection and to reduce the memory footprint in some data
structures, let us use a uint32_t for the page number, instead
of ulint (size_t) which can be 64 bits.
