Subject: Add support for hex notation for uint64 type

Specifically, now we can do:

x = [uint64] 0x0000ffff

cxx.poptions += "-DOFFSET=$x"                 # -DOFFSET=65535
cxx.poptions += "-DOFFSET=$string($x, 16)"    # -DOFFSET=0xffff
cxx.poptions += "-DOFFSET=$string($x, 16, 8)" # -DOFFSET=0x0000ffff

Note that there is no hex notation support for the int64 (signed) type.
