Markus Armbruster 00382fa851 json: Fix to reject duplicate object member names
The JSON parser happily accepts duplicate object member names.  The
last value wins.  Reproducer #1:

    $ qemu-system-x86_64 -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 93, "minor": 0, "major": 3},
    "package": "v3.1.0-rc3-7-g87a45d86ed"}, "capabilities": []}}
    {'execute':'qmp_capabilities'}
    {"return": {}}
    {'execute':'blockdev-add','arguments':{'driver':'null-co',
     'node-name':'foo','node-name':'bar'}}
    {"return": {}}
    {'execute':'query-named-block-nodes'}
    {"return": [{ [...] "node-name": "bar" [...] }]}

Reproducer #2 is iotest 229.

Fix the parser to reject duplicates, and fix iotest 229 not to use
them.
