jvpp: object model for jvpp generator (VPP-1184)

Introduces JSON parser which builds object model of Java API.

Also rewrites JNI translation of typedefs
to use per type translation functions
instead of code inlining.

Not covered:
- integrate with vappigen plugin (VPP-1154) or vapi parser (VPP-1155)
- use better templating engine (VPP-480)
- improvements of generator structure (e.g. VPP-1186)
