[svn-r4605]
Purpose: Bug fix Description: Add the overloaded member function Attribute::getName to return the attribute name's length as in C API. This functionality was missing. Note that the current getName that returns "string" is not removed, for different way of using getName. Platforms tested: SunOS 5.7 (arabica) Windows 98
