Now it no longer tries to be this weird hybrid between an owning
and non-owning reference, and is only ever non-owning. This is also
reflected in its interface, for example `StringRef::isNullTerminated`
is now public, and `StringRef::c_str()` has the precondition that it
is true.
Overview of the changes:
* The `StringRef::m_data` member has been completely removed, as it
had no more uses.
* `StringRef::isSubstring()` has been made public and renamed to
`StringRef::isNullTerminated()`, so that the name reflects what the
method actually does.
* `StringRef::currentData()` has been renamed to `StringRef::data()`,
to be in line with common C++ containers and container-alikes.
* `StringRef::c_str()` will no longer silently make copies. It instead
has a precondition that `isNullTerminated()` is true.
* If the user needs a null-terminated string, they should use the
`std::string` conversion operator and call `c_str()` on the resulting
`std::string`.
* Some small optimizations in various places.
* Basic functionality is now `constexpr`.
Unless someone steps up to fix the long link times with a set of
unobtrusive changes, the recommended solution will remain "use a better
linker".

This should now properly handle small numbers which would previously
output something like `[0.00000000000000019, 0.00000000000000019]`,
which does not allow user to read the numbers properly.
Closes#1760
this warning was introduced by rework to support NTTPs
since we have implementation macro for NTTPs and normal template test cases
warning is going to be suppressed
Fixes#1762
Only works for exceptions that publicly derive from `std::exception`
and the matching is done exactly, including case and whitespace.

It checks Knuth's _close enough with tolerance_ relationship, that
is `|lhs - rhs| <= epsilon * max(|lhs|, |rhs|)`, rather then the
_very close with tolerance_ relationship that can be written down as
`|lhs - rhs| <= epsilon * min(|lhs|, |rhs|)`.
This is because it is the more common model around the internet, and
as such is likely to be less surprising to the users. In the future
we might want to provide the other model as well.
Closes#1746
This means that if you nest multiple random generators inside one
test case, they will not return the same sequence of numbers.
Idea taken from #1736 by Amit Herman.
Closes#1736Closes#1734
In the future, we will also want to introduce our own
`uniform_int_distribution` and `uniform_real_distribution` to get
repeatable test runs across different platforms.
Wrong nesting of namespaces resulted in the `Catch` namespace
being ambigous between `::Catch` and `::{anon}::Catch` namespaces.
This should fix it.
Closes#1761
Instead, let it be installed as a dependency of `conan-package-tools`
to avoid trouble with the fact that pip is really bad at version
resolution, and that up-to-date version of the `conan` package is not
supported by up-to-date version of the `conan-package-tools` package.
