* Added c++17 test configurations for clang5.0 and clang6.0
* removed GSL_NOEXCEPT
- Removed GSL_NOEXCEPT macro
- Replaced by noexcept keyword when needed
- removed noexcept where a function could throw
* remove unneded undef
* fixed replace errors
* removed noexcept where function can throw
not called even by the unit test (it was calling the "container" ctor
instead). I mimicked the constructor taking a non-const std::array to fix
the issue.
Project files were not following the clang-format style. For people
using IDEs were clang-format is always run after a save this would
cause unwanted changes.
This commit only applies "clang-format -i" to files.
* Nest "gsl" directory inside a new "include" directory.
* Cleanup the _MSC_VER conditionals a bit; use constexpr on VS2017+.
* Don't #define noexcept on non-Microsoft implementations.
* Workaround VS2017 bug in multi_span. (Also implement == and != for static_bounds_dynamic_range_t because I'm an EoP semantic soundness snob.)
Fixes#441.
