[OPEN-ILS-DEV] PATCH: osrf_json_tools.c (const-correctness)

[Scott McKellar]

These patches fine-tune some const-correctness in osrf_json_tools.c.

1. I changed the signature of jsonObjectDecodeClass so that it accepts
a non-const pointer parameter.  Since it doesn't change the contents
of the jsonObject, there's no need to confine it to non-const
jsonObjects.

2. I replaced jsonObjectGetKey() with jsonObjectGetKeyConst().

3. In one spot I captured the return value of jsonObjectGetIndex()
with a const pointer instead of a non-const pointer.

The second item above relies on the prior application of a previous
pair of patches that I submitted earlier today.
