Move reportAmbiguity, reportContextSensitivity, reportAttemptingFullContext, reportInsufficientPredicates from ANTLRErrorStrategy to ANTLRErrorListener.
...
Add BaseErrorListener to allow implementing ANTLRErrorListener without implementing every method (e.g. ConsoleErrorListener).
DiagnosticErrorStrategy is now DiagnosticErrorListener, updated tests.

* Recognizer._listeners initialized to have a single ConsoleErrorListener
...
* Use CopyOnWriteArrayList so listeners can be added/removed in callbacks
* Remove special handling for _listeners null or empty (never null, ConsoleErrorListener will be present if feature is desired)

Add boolean field ParserATNSimulator.reportAmbiguities (default true). When false, ambiguous alts aren't reported which allows usage of (the faster) incomplete semantic predicate evaluation even within execATN.

Evaluate predicates for all ambiguous alternatives and report if still ambiguous after predicate evaluation. Remove misleading message insufficient predicates. Fixes antlr/antlr4#31 . Partially addresses antlr/antlr4#39 .

Added ParseTreeProperty and added generically useful Map that ignores key.hashCode and equals() and simply uses key identity instead. In particular, this is useful for ANTLR because parse trees are actually interfaces laid on top of the rule context objects used by ANTLR's grammar analysis. These context objects use special equals methods and so on. Plus, when we want to annotate trees with values, we want a specific note to have a value. Identity is what we intend.
