Issue MESOS-3449: Expand the range of integer precision in json <-> protobuf conversions to include unsigned integers
The previous changes (MESOS-3345) to support integer precision when converting JSON <-> Protobuf did not support precision for unsigned integers between {{INT64_MAX}} and {{UINT64_MAX}}. (There's some loss, but the conversion is still as good/bad as it was with doubles.) This problem is due to a limitation in the JSON parsing library we use (PicoJSON), which parses integers as {{int64_t}}. Some possible solutions or things to investigate: * We can patch PicoJSON to parse some large values as {{uint64_t}}. * We can investigate using another parsing library. * If we want extra precision beyond 64 or 80 bits per double, one possibility is the [GMP library|https://gmplib.org/]. We'd still need to change the parsing library though.
