plug mem leak from flex parser for C++

                 Key: AVRO-117
                 URL: https://issues.apache.org/jira/browse/AVRO-117
             Project: Avro
          Issue Type: Bug
          Components: c++
            Reporter: Scott Banachowski
         Attachments: AVRO-117.patch

Valgrind reports a leak coming from the flex parser generated code.

The flex-generated lexer allocates memory to use for its state stack.  Examining this code
it is clear that once allocated, the stack is never freed.  Since I cannot easily replace
flex code, I inserted the code to free the stack as a lexer rule.  

Valgrind is happy with the result.
