Python: add public getter to parsers to access syntax error count. 

ANTLR parsers in Java are allowed to access the number of encountered
syntax errors via the getNumberOfSyntaxErrors method. However, the
Python variants must use the protected _syntaxErrors member to get this
value. The patch defines the same getter for Python targets too.
