// A JSON parser that can parse a stream of JSON chunks rather than needing the
// entire JSON string up front. It is a modified version of the parser in
// //net/proto/json/json-parser.h that has been changed in the following ways:
// - Changed from recursion to an explicit stack to allow resumption
// - Added support for int64 and uint64 numbers
// - Removed support for octal and decimal escapes
// - Removed support for numeric keys
// - Removed support for functions (javascript)
// - Removed some lax-comma support (but kept trailing comma support)
// - Writes directly to an ObjectWriter rather than using subclassing
//
// Here is an example usage:
// JsonStreamParser parser(ow_.get());
// util::Status result = parser.Parse(chunk1);
// result.Update(parser.Parse(chunk2));
// result.Update(parser.FinishParse());
// GOOGLE_DCHECK(result.ok()) << "Failed to parse JSON";
//
// This parser is thread-compatible as long as only one thread is calling a
// Parse() method at a time.
