Issue MESOS-3698: JSON parsing allows non-whitespace trailing characters
Picojson supports a streaming mode in which a stream containing a series of JSON values can be repeatedly parsed. For this reason, it does not return an error when passed a string containing a valid JSON value followed by non-whitespace trailing characters. However, in addition to the four-argument {{picojson::parse()}} that we're using, picojson contains a two-argument {{parse()}} function (https://github.com/kazuho/picojson/blob/master/picojson.h#L938-L942) which accepts a {{std::string}} and should probably validate its input to ensure it doesn't contain trailing characters. A pull request has been filed for this change at https://github.com/kazuho/picojson/pull/70 and if it's merged, we can switch to the two-argument function call. In the meantime, we should provide such input validation ourselves in {{JSON::parse()}}.
