[OPEN-ILS-DEV] json mergin' time

[Bill Erickson]

For those of you following code commits, you'll notice a good bit of
activity in the OpenSRF new-json2 branch.  We've reached a point where the
new protocol is (testing shows) fully backwards compatible with existing
code.  In short, you can install the new-json2 branch over an existing
install (e.g. Evergreen install), restart services, and all will be well.
The main noticable difference will be what you see in srfsh responses:

EXAMPLE:

* LEGACY protocol
------------------------------------------------------------------------

srfsh# request open-ils.cstore
open-ils.cstore.direct.actor.org_unit.retrieve 1

Received Data: /*--S aou--*/[
   null,
   null,
   null,
   null,
   1,
   1,
   1,
   1,
   1,
   "PINES",
   1,
   null,
   "PINES",
   null,
   null,
   "t"
]
/*--E aou--*/


* NEW protocol
-----------------------------------------------------------------------------

srfsh# request open-ils.cstore
open-ils.cstore.direct.actor.org_unit.retrieve 1

Received Data: {
  "__c":"aou",
  "__p":[
    1,
    1,
    1,
    1,
    1,
    "PINES",
    1,
    null,
    "PINES",
    null,
    null,
    "t"
  ]
}


The new JSON protocol will be merged into OpenSRF trunk in preparation for
OpenSRF 1.0.  It won't be merged into STABLE_0_9, just to be clear.

Evergreen 1.4 will require OpenSRF 1.0 because of the new JSON code.

The Evergreen 1.2 branch should work with either OpenSRF STABLE_0_9 or
OpenSRF 1.0

I'll be merging the changes today, unless there is any hollering :)

For the really curious:
