Eric Fischer b72bb6f1f4 Clean up after errors and fix related bugs: 
It was freeing the wrong object when there was an error
attaching an object to its parent!

Don't crash when printing null (partially read) hash values.

Eric Fischer f67e97cd08 Work out more details of how json_free() needs to work. 
The idea is that you can free any element once you are
done with it, even if it is part of an array or hash that
isn't completely read yet.

Removing array elements is reasonably well defined because
nothing else depends on them. Removing a hash key or value
causes it to be replaced by a null unless the other side of
the component has already been nulled out, in which case
the whole pair is removed.

Eric Fischer 979b9243d8 A container object makes the state transitions more straightforward 
And should make it possible to free an object that has just been read
and still know what the next state will be, importantly.

Eric Fischer 6449e817b6 Detect attempts to attach an element to a non-container parent. 
Maybe there is a better name for this. The typical case is adjacent
tokens not separated by a comma.

Eric Fischer 42283ece0b More sensible way of passing errors back to caller 2014-02-06 12:13:23 -08:00
Eric Fischer f8465828e5 Maybe the right way to handle empty arrays? 
The previous check for the array length being 0 didn't work
for the case of an array that contains only an empty array.

The tricky part is that the current node is the array when
the array has just begun or just after a comma, but also
when the completed array has been passed off to the caller.
