uint256S was previously deprecated for being unsafe. All non-test
usage has already been removed in earlier commits.
1. Tests now use uint256::FromHex() or other constructors wherever
possible without further modification.
2. Tests that can't use uint256::FromHex() because they use input
with non-hex digit characters are
a) modified by dropping the non-hex digit characters if that
provides useful test coverage.
b) dropped if the test without non-hex digit characters does
not provide useful test coverage, e.g. because it is now
duplicated.
Additionally, use BOOST_CHECK_EQUAL where relevant on touched lines
to make error messages more readable.
