Dev/annagrin/remove explicit not null constructor (#743)
* Added c++17 test configurations for clang5.0 and clang6.0

* Removed explicit not_null constructor, sloppy_not_null, added strict_not_null

We added explicit not_null constructor in version 2.0.0.
It proved very difficult to switch to the new version for
large code bases that adopted previous versions of gsl,
due to not_null used extensively in the code. Still, using
explicit constructor is very benefitial for new code, since
it encorages better API design and make null checks intentional.

To resolve the issue, this change:
- removes explicit keyword from not_null constructor
- removes unneded sloppy_not_null type
- adds strict_not_null type to behave the same way as v2 not_null
- updates tests

Dev/annagrin/make not null (#711)
* Added c++17 test configurations for clang5.0 and clang6.0

* Added make_not_null helper to create a not_null

Introduction of explicit not_null constructor made it cumbersome to create not_nulls
in c++14. Adding make_not_null helper. Usage (see tests):

int i = 42;

auto x = make_not_null(&i);
helper(make_not_null(&i));
helper_const(make_not_null(&i));

cea0d0ac2b fix cppcorecheck warnings (#703)
* Added c++17 test configurations for clang5.0 and clang6.0

* Fixed CppCoreCheck warnings in GSL and tests

- Added CMakeSettings.json for VS Open Folder configuration
	- So we can easily run CppCoreCheck in VS
- Fixed CppCorecheck warnings where it made sense
- Suppressed the rest
	- Some suppression does not work due to compiler/tool bugs,
          so replaced by #pragma disable
	- CppCoreCheck has noise, suppressed those with comments
	- Catch produces many warnings, blanket-supressed them all
- Had to fix clang formatting to keep attributes in place
	- clang-format does not support attributes, so I am using
        - "CommentPragmas: '^ NO-FORMAT:'" to skip formatiting on them
- Removed GSL_NOEXCEPT macro, removed incorred noexcepts

* Ignore unknown attributes

* ignore unknown attributes in noexception mode tests

* fixed C26472 in at()

* created GSL_SUPPRESS macro to allow all compilers to parse suppression attributes

* try to fix gcc compilation problems with attributes

* ignore gsl::suppress for gcc

* move suppression to function level on return statements

clang5.0 and up does not allow attributes on return statemets in constexpr functions

* move suppression to function level on return statements

* use GSL_SUPPRESS in algorithm_tests

* Addressed PR comments

b6c531f7c1 Explicitly check for availability of std::byte (fixes #713) (#714)
* Explicitly check for availbility of std::byte

GCC > 7.3 defines __cpp_lib_byte >= 201603 when std::byte is available.
On libc++ std::byte is available since version 5.0. This can be checked
with _LIBCPP_VERSION >= 5000.
This fixes 713.

Added template argument deduction for not_null (#689)
* Added template  argument deduction for not_null

This allows compilers with c++17 support to infer template
instantiation types when calling not_null constructor:

    int foo(not_null<const int*> x);

    int main()
    {
        int t = 0;
        not_null x{ &t };
        return foo(not_null{ &t });
    }

* replaced deduction guides by a simple constructor

* Updated tests

* fixed check for availability of std::byte

* testing c++1z on clang

* fixed cmakelists extra endif

* include cstddef header for clang and gcc in pointers

* fixed a typo

* fix missing nullptr_t type

* fixed typo in CMakeLists.tst

* change approach to c++17 testing, step one: revert cmake testing, update clang5.0 package

removed using latest c++ due to clang5.0 failing,
update clang5.0 travis config to use llvm-toolchain-trusty-5.0

* addressed comments

Add usage for check-and-unwrap of MS STL iterators (#687)
* Add usage for check-and-unwrap of MS STL iterators

This is Billy ONeal's PR #682 with a typo fixed.

See corresponding change here:
ca77129308
That change officially exposes the STL's range checking machinery,
available in MSVC++ "15.8"+
This change augments GSL span::iterator to call into that newly exposed
machinery.

_Verify_range(cit, cit)
Requests that the iterator type check that the parameters form a valid
[First, Last) range iterator pair. This replaces _DEBUG_RANGE and
supporting machinery. The standard library provides a version for
pointers under _IDL != 0; otherwise they are normally provided via
hidden friend functions. Note that declaring some of these hidden
friends for "wrapper" iterators like move_iterator and reverse_iterator
triggers VSO#610735.

cit._Verify_offset(difference_type _Off)
For random-access iterators, performs any asserts that would be
performed by i += _Off; except with possibly a better error message and
without moving the iterator.

cit._Unwrapped()
Returns an "unchecked" or "unwrapped" iterator which has previously been
validated. The iterator may have been validated by a call to
_Verify_range or _Verify_offset (above), or by seeking a checked
iterator to a "high water mark" point.

it._Seek_to(cit) / it._Seek_to(return value from _Unwrapped())
Moves the position of the checked iterator it to the position of the
unchecked iterator supplied. Generally not intended to perform range
checks.

d6b26b367b Add __may_alias__ attribute to gsl::byte (#668)
C++17 defines `std::byte*` to have the same aliasing properties as
`char*`. Hence, we mark it with the `__may_alias__` attribute under gcc
and clang.

Based on the fix by Martin Moene in byte-lite.

9c5e21045d Make gsl::details::throw_exception not copy exception object (#667)
This fixes the build with clang 7 which introduces a new warning
`-Wreturn-std-move` which warns about needless copies when a move
operation is available (see https://reviews.llvm.org/rL329914).

We take the exception object by uref so we should throw the forwarded
version.

Enable usage of gsl::narrow with exceptions disabled (#640)
* Enable usage of gsl::narrow with exceptions disabled

This solution uses the approach of boost::asio to enabling usage of the
library in environments where exception usage is either prohibited
or not feasible (due to code size constraints). A function template
gsl::throw_exception has been added, which in a normal environment just
throws the exception. However, when GSL_TERMINATE_ON_CONTRACT_VIOLATION
is defined the function is only declared by gsl and the definition of
this function template must be supplied by the library's user.

Closes: #468
