The lexer and parser ATN simulators' adaptivePredict now synchronize on the specific DFA of the decision to be simulated. This should prevent a lot of contention that would occur if we synchronize the entire adaptivePredict method. When the individual DFA are created, we also synchronize on the shared DFA[] table quickly to create a DFA and insert it into the array. Code generation modified to have _decisionToDFA generated at the top of both the parser and the lexer. Simulators created now with the recognizer, ATN, DFA[]. Not sure the LexerInterp/ParserInterp work but pushing ahead anyway for the moment.

reorg closure and fix bug where $ in arrayctx wouldn't perform global follow. fix case in array merge that didn't check both a[i], b[i] as $ (only matters in full ctx). unit tests for graph show fewer ctx's created.

CommonTokenFactory now knows how to copy the text out of the character stream buffer before they disappear in unbuffered character strengths; added ctor.
...
Lexer now guarantees that the text of the current token is always available to the emit() method even if the character stream is unbuffered.
Added some hooks to see some of the internal data in the unbuffered character stream so that I can test it better.
Updated LexerInterpreter so that it uses the token factory.
Improved/added unit tests for the unbuffered character string.
Updated various comments

fix a bug related to semantic predicates in the lexer and generally cleaned up variable and method names in the simulator. I moved all of the predicates to the right side of lexer rules in the unit tests. Later, we should ensure that predicates only occur on the right edge of lexer rules. We should state that the rule is not been accepted so we can't test things like getText(), we have to use more raw indexes into the character stream. In the lexer simulator, the addDFAState() method now does not try to compute whether there is a predicate in the configurations. That information has already been set into the ATNConfigSet by the getEpsilonTarget() method. [I should also point out that I have not tested the Java parsing in a while and now it hits a landmine on a number of common Java files in jdk :(. I'm not sure where that crept in]

added listener unit tests. fixed bug that didn't create ctx getters properly for recursive rules. added Symbol extends Token to parse tree stuff. added visitTerminal to Visitor. recursive alts now track their original, unedited AltAST subtree so we can properly count rule refs etc... later. dup of RuleRefAST was making wrong node. don't gen dispatch methods if no listener.
