- Allow to register handler separately for invalid memory access - Add new memory events for hooking: - UC_MEM_READ_INVALID, UC_MEM_WRITE_INVALID, UC_MEM_FETCH_INVALID - UC_HOOK_MEM_READ_PROT, UC_HOOK_MEM_WRITE_PROT, UC_HOOK_MEM_FETCH_PROT - Rename UC_ERR_EXEC_PROT to UC_ERR_FETCH_PROT - Change API uc_hook_add() so event type @type can be combined from hooking types
