@ahayashi do you need to add a CMake option so that we can turn this XACC_MUTEX preprocessor flag on and off? I'd prefer to see -DXACC_MULTI_THREADED=TRUE |

@amccaskey yes, I agree and will do! |
Add thread-safety to XACC/QCOR (Experimental). We introduce `_XACC_MUTEX` macro in `xacc.hpp` to turn on/off the feature (default is OFF). When the macro is ON, only a single thread can execute the following routines by using either `std::mutex` or `std::recursive_mutex`:
- User-facing API routines
- `xacc::qalloc()`
- Backend modules
- `QppAccelerator`
- `execute()` (the existing shot-level parallel execution still works)
- `apply()`
- `NLOptimizer`
- `optimize()`
Also, regardless of the macro, the `NLOptimizer` class is now `xacc::Cloneable`.
