The StringMaker is off by default and can be enabled by a new macro `CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER`, to avoid increasing the footprint of stringification machinery by default.
This means
* Adding new configuration toggle `CATCH_CONFIG_DISABLE_EXCEPTIONS`
and a best-guess configuration auto-checking for it.
* Adding new set of internal macros, `CATCH_TRY`, `CATCH_CATCH_ALL`
and `CATCH_CATCH_ANON` that can be used in place of regular `try`,
`catch(...)` and `catch(T const&)` respectively, while disappearing
when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is enabled.
* Replacing all uses of `throw` with calls to `Catch::throw_exception`
customization point.
* Providing a default implementation for the above customization point
when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is set.
* Letting users override this implementation with their own.
* Some minor changes and ifdefs all around to support the above
issue #1360
It is possible to have multple given contexts in a single BDD scenario;
if you have to type 'and' in the GIVEN description; it's very likely you
need an AND.
A generic AND is not possible, thus a AND_GIVEN is added to complement
the AND_WHEN and AND_THEN.
Can be used without needing to increase indent:
SCENARIO("...") {
GIVEN("...")
AND_GIVEN("...") {
WHEN("...") {
THEN("...") {
// ...
}
}
}
}
would correctly output, when requested/needed:
Given: ...
And given: ...
When: ...
Then: ...
The padding had to be increased by a character in the output message, to
continue to be uniform.
The support is to be considered experimental, that is, the interfaces,
the first party generators and helper functions can change or be removed
at any point in time.

In case of 2 instances of SourceLineInfo constructed in the same
file, they will have the same `file` pointer (even at O0). Thus, we
can check if they are equal before calling potentially pointless
`strcmp`.
In theory the copy is cheap (couple of pointers change), but tests
are usually compiled in Debug mode/with minimal optimizations, which
means that most users will still have to pay the cost for those
function calls.
Because the macro name is compile-time constant, we do not have to
worry about lifetimes and will avoid allocation in case of missing
SSO or long macro name.
By opting the JUnit and XML reporters into it, we no longer run
into problem where they underreport the results without `-s` flag.

- seems the #ifdef was necessary after all, because of the difference in the way the cpp files are included in the full project vs the single include
- in the OC project I moved the #include of catch_tostring.cpp first. That solves the project for now, but is a brittle solution
Happening when using clang and templated operators, clang cannot decide
between the operator provided by ReusableStringStream and the one provided
by the value value as both are templates. This is easily solved by calling
the operator<< through the member syntax.

This was removed in 64be2ad, to fix OS X approval tests. At the time
I couldn't investigate because I didn't have access to OS X, but this
fixed it (and since we don't have MinGW in CI, the breakage went
unnoticed).
As it turns out, piece-wise compilation of the Compact
reporter had broken OS X detection for a long time, and fixing it
was what broke the approvals. After the approval scripts were
changed to compensate, this change passes approval tests and fixes
Until now, the stack size for POSIX signal handling was determined by
the implementation defined limit `STKSZ`, which in some cases turned out
to be insufficient, leading to stack overflow inside the signal handler.
The new size, which was determined experimentally, is the larger of 32kb
or `MINSTKSZ`.
Fixes#1225
This should align more closely with the intended semantics, where
types without `StringMaker` specialization or `operator<<` overload
are passed down to the user defined fallback stringifier.

This support is based on overriden `std::exception::what` method, so
if an exception does not do so meaningfully, the message is still
pointless.
This is only used as a fallback, both `StringMaker` specialization and
`operator<<` overload have priority..
Android apparently does not support `std::to_string`, so we add a
small polyfill over it. Right now only the ULP matcher uses it,
but we have had plans to use it in `StringMaker<int>` and friends,
as it performs a lot better than `std::stringstream` based
stringification on MSVC.
See #1280 for more details
