Added oic.r.pstat Property "dos" as made mandatory by
OCF Security Specification CR 23.

patch set 2: Functional cbor marshalling.

patch set 3: Updated json2cbor tool and every svr.json and
.dat file I could find to use the new pstat.dos property.

patch set 4: Updated json2cbor tool to support oic 1.1 format

and addressed misc comments on patch set 5.
