Add an explicit intermediate YANG representation

ANTLR classes are geared towards parsing and raw speed, without much
regards to memory usage. Most notably using ParseTree as our AST ends
up retaining separators and various metadata which we do not really
need.

Add a simplistic intermediate representation for our AST, which where
we pre-process ANTLR trees and de-duplicate strings. This leads to
elimination of 90% of objects, with corresponding reduction of memory
footprint.
