Johann 1161055129 Be consistent with SAD values
SAD returns unsigned values. Make all the declarations the same.

Remove bestsad initialization and check. It is always set to the
result of a SAD call so it will never remain UINT_MAX

Use ja instead of jg to test unsigned comparison instead of signed.

Update test.
