Julien Fischer 52b31f5089 Add uint64 to string conversion for bases 8 and 16.
library/string.m:
     Add functions for converting uint64s to strings of base 8 or base 16
     digits. For most integer types we can cast to a uint and then use the
     uint versions of these operations but for 64-bit types we cannot since
     on some of our supported platforms uints are 32-bit.

NEWS:
     Announce the additions.

tests/hard_coded/Mmakefile:
tests/hard_coded/uint64_string_conv.{m,exp}:
     Add a test of the new functions.
