Util: Update json-simple lib to 2.3.0 2017-10-04

Bundle 2.0 API only; remove 1.1 API
Convert DoH, NDT, and i2pcontrol to the 2.x API
Fix i2pcontrol handling of number values and serialization for 2.x API
Remove xenial dependency on libjson-simple-java, it has only 1.1
Set min and max version constraint on libjson-simple-java for bionic+
Based on patch from Gilles Filippini
ref: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901827
This does not support 3.x but the patch for that will be smaller.
