This doesn't fix the JSON parser, it "fixes" one of its users! Other
users remain broken. Reproducer for QMP (already mentioned in my review
of the previous patch):
$ echo -e '{ "execute": "qmp_capabilities" }\n{ "execute": "query-name"
}\n"unterminated' | socat UNIX:test-qmp STDIO
{"QMP": {"version": {"qemu": {"micro": 90, "minor": 12, "major": 2},
"package": "v3.0.0-rc1-20-g6a024cd461"}, "capabilities": ["oob"]}}
{"return": {}}
{"return": {}}
Note there's no error reported for the last line.
The simplification of the JSON parser I have in mind might make this
easy to fix properly. I'll look into it.
