Michael Roth 5e2dafeb19 json-streamer: add handling for JSON_ERROR token/state
This allows a JSON_ERROR state to be passed to the streamer to force a
flush of the current tokens and pass a NULL token list to the parser
rather that have it churn on bad data. (Alternatively we could just not
pass it to the parser at all, but it may be useful to push there errors
up the stack. NULL token lists are not currently handled by the parser,
the next patch will address that)

Luiz Capitulino 2e89c06889 json-streamer: Don't use qdict_put_obj()
It's not needed, use qobject_put() instead and get a cleaner code.

Anthony Liguori d7ff3acbb4 Add a JSON message boundary identifier
The second stage of our JSON parser is a simple state machine that identifies
individual JSON values by counting the levels of nesting of tokens.  It does
not perform grammar validation.  We use this to emit a full JSON value to the
parser.
