David Benjamin 719220ec8e Get overflow checks right in BN_bin2bn. ... BN_bin2bn takes a size_t as it should, but it passes that into bn_wexpand which takes unsigned. Switch bn_wexpand and bn_expand to take size_t before they check bounds against INT_MAX. BIGNUM itself still uses int everywhere and we may want to audit all the arithmetic at some point. Although I suspect having bn_expand require that the number of bits fit in an int is sufficient to make everything happy, unless we're doing interesting arithmetic on the number of bits somewhere.
