This commit continues the PR #111

- 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
