revert integer literal suffixing again and instead generate C hex literals if no suffix is used to make the C compiler consider unsigned types for their values (see C standard 6.4.4)

Allow passing more than two -v's to cygdb.

Constants in float.pxd are not integers.

Additions to includes

- append U-suffix only on coercion when the target type is unsigned
- append L/LL-suffix when value looks too large for a smaller constant value type
