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.

P.S.: an assert(state.result != NULL) statement in
qobject_from_jsonv() will be good for asserting failure of parsing
JSON strings.

 Hm, I guess this has been suggested before... Anthony?

 Yes, this change is already in a series I plan to send shortly.

 Thanks a lot for tracking this down.

I asked for the json parser changes to be split from the PRId64 
changes.  It was never resubmitted.  I'll apply your patch.
