[OPEN-ILS-DEV] purging objson (legacy json) for opensrf 1.0 / Evergreen 1.4

[Bill Erickson]

The topic of purging objson, which implements the old-style, comment-embedded 
class hints for OpenSRF objects came up recently during a discussion of the 
new autotools infrastructure.  OK, fine, I brought it up.  

The current objson setup provides support for parsing old-style objects via a 
separate API call (used in the opensrf gateway) and an implementation of the 
old jsonObjectIterator API, which changed with the latest JSON code.

The original idea for the legacy json layer was that the system may need to 
support old and new-style JSON objects for Evergreen 1.4.  However, if we are 
in agreement that there is no need to support old-style JSON objects in 
Evergreen 1.4, and I'm pretty sure we've passed that bridge already, then the 
legacy JSON layer seems like an unnecessary layer of complexity that we 
should just drop.       

What would it take?

1. The cstore application makes heavy use of the jsonObjectIterator API, which 
would need to be manually updated to use the new jsonIterator API.  The 
difference there is that the call to next() now returns a jsonObject instead 
of a the intermediary jsonObjectNode.  Also, instead of accessing the current 
key through the node, you access it directly on the iterator object.

2. Remove all references to objson on the source/makefiles for Evergreen (only 
a few remain)

3. Purge objson from OpenSRF autotools and remove osrf_legacy_json* files

Sound sane for Evergreen 1.4 and OpenSRF 1.0?
