For this particular RFE, it enhances SunPKCS11 provider to load PKCS#11 provider by first trying the C_GetInterface (new in 3.0) before the C_GetFunctionList assuming not explicitly specified in config. In addition, PKCS#11 v3.0 defines a new API for cancelling session operations, so I've also updated various classes to call this new API if the PKCS#11 library version is 3.0. Otherwise, these classes will try to cancel by finishing off current operations as before. The support for the new C_LoginUser() has not been tested, so I commented it out for now. Given the current release schedule, support for other new PKCS#11 APIs (such as message-based ones and parameters structure) and options for C_GetInterface (if needed) will be handled later.

Sure, I can do that. I tend to use the "->" for switch with less items.
