MISRA C:2012 Rule 7.2 (A `u' or `U' suffix shall be applied to all
integer constants that are represented in an unsigned type)

Added missing `U' suffixes in constants that are involved in the
analyzed build, plus a few more not to introduce inconsistencies
with respect to nearby constants that are either unused in the
build (but implicitly unsigned) or are used and are immediately
converted to unsigned.
