I took the liberty to rebase this onto my "[PATCH 00/56] json: Fixes,
error reporting improvements, cleanups", which is by the way also
available at
http://repo.or.cz/qemu/armbru.git/shortlog/refs/heads/json-fixes

Kept (not really part of this series, as noted above)

Kept, has my R-by.

I figure the last two need to be considered in context of OOB work that
hasn't landed, yet.  Discussed in review of v1.

>   qga: process_event() simplification and leak fix

Already in master as commit ae7da1e5f6.

>   qmp: drop json_parser_parse() wrapper

Replaced by my series.

>   json-parser: simplify and avoid JSONParserContext allocation

Picked into my series.

>   qjson: report an error if there are multiple results
>   qjson: report error on unterminated string
>   qjson: return parsing error if unterminated input
>   json-parser: set an error if parsing returned NULL

Replaced by my series.

Kept, only the success-response test has my R-by.

Result:
