Subject: Ticket 49268 - master branch fails on big endian systems


Bug Description:  We had a number of tests that did not function
on a bigendian system, or a system with different pagesizes

Fix Description:  Correct the tests to set the page size to a known
value. Fix the hashtest to use correct endianness for inputs.
