The commit makes the following refinements in GenFw source codes to
avoid VS2010/VS2012 build failure:
1. Replaces the uses of 'bool' with 'BOOLEAN' for accordance, and remove
the header file dependency for '<stdbool.h>'.
2. Refines coding style for function 'GetSymName' to declare local
variables at the beginning of the function block.
