[PATCH 2/4] format: Use json_object_object_get_ex() instead of deprecated json_object_object_get()

[pmeerw@xxxxxxxxxx (Peter Meerwald)]

From: Peter Meerwald <p.meerwald@xxxxxxxxxxxxxxxxxx>

pulse/format.c:680:9: warning: 'json_object_object_get' is deprecated (declared at /usr/local/include/json-c/json_object.h:290) [-Wdeprecated-declarations]

json-c 0.10 (released 20120530) added json_object_object_get_ex()
json-c 0.12 (released 20140410) deprecated json_object_object_get()

PulseAudio depends on json 0.9 or json-c 0.11, drop support for json 0.9
in a subsequent patch and require json-c 0.11 (this will also avoids confusion
which json package is needed due to the upstream rename)
