Support init params for C_Initialize function

[microshine]

Cryptoki params

typedef struct CK_C_INITIALIZE_ARGS {
  CK_CREATEMUTEX CreateMutex;
  CK_DESTROYMUTEX DestroyMutex;
  CK_LOCKMUTEX LockMutex;
  CK_UNLOCKMUTEX UnlockMutex;
  CK_FLAGS flags;
  CK_VOID_PTR pReserved;
} CK_C_INITIALIZE_ARGS;

NSS params

typedef struct CK_NSS_C_INITIALIZE_ARGS {
    CK_CREATEMUTEX CreateMutex;
    CK_DESTROYMUTEX DestroyMutex;
    CK_LOCKMUTEX LockMutex;
    CK_UNLOCKMUTEX UnlockMutex;
    CK_FLAGS flags;
    CK_CHAR_PTR LibraryParameters;
    CK_VOID_PTR pReserved;
} CK_NSS_C_INITIALIZE_ARGS;

It would be nice to use something like NSS CK_CHAR_PTR LibraryParameters
