Michael Roth c1990ebfa1 json-parser: add handling for NULL token list
Currently a NULL token list will crash the parser, instead we have it
pass back a NULL QObject.

Amos Kong c96c84a9ff json-parser: Output the content of invalid keyword
When input some invalid word 'unknowcmd' through QMP port, qemu outputs
this error message:
  "parse error: invalid keyword `%s'"

This patch makes qemu output the content of invalid keyword, like:

  "parse error: invalid keyword `unknowcmd'"

Kevin Wolf d758d90fe1 json-parser: Fix segfault on malformed input
If the parser fails to parse the key in parse_pair, it will access a NULL
pointer. A simple way to trigger this is sending {foo} via QMP. This patch
turns the segfault into a syntax error reply.

Roy Tam 2c0d4b36e7 json: fix PRId64 on Win32
OK we are fooled by the json lexer and parser. As we use %I64d to
print 'long long' variables in Win32, but lexer and parser only deal
with %lld but not %I64d, this patch add support for %I64d and solve
'info pci', 'powser_reset' and 'power_powerdown' assert failure in
Win32.

Anthony Liguori 4a5fcab7ac Add a JSON parser
This is the third and final stage of the JSON parser.  It parses lexical tokens
performing grammar validation and creating the final QObject representation.  It
uses a recursive decent parser.
