As it turns out, we can probably do much better by providing a customized token factory.</p> YANGTOOLS-1128

Add a dedicated ANTLR token factory

Nominally we can reduce the footprint by about 15% through use of memory-optimized Token implementation. Since ANTLR needs to track location for each token, further improvement can be made by post-processing the parse tree and replacing tokens with location-independent implementation.</p> Blocks YANGTOOLS-1129 Issue split YANGTOOLS-1130 Development Rank 0|i03uef:
