description:
libdes: suppress some selected lint warnings

The type widths are handled carefully, so even if there is some
conversion from 64-bit long to uint32_t, no value bits get lost.

The fallthrough case statements are a variant of Duff's Device.

The bitwise '>>' on signed value is actually on a value of type
'unsigned char', and since all platforms supported by lint have
sizeof(int) == 4, the behavior is well defined.
