The cached handle would become invalid if some other code, say
a user-provided test code, redirects stdout through `freopen`
or `_dup2`, which would then cause AppVerifier to complain.
Fixes#2345
At one point it was inserted there as the simplest way to smuggle
around an extra return value for specific errors in executing
tests. Since then, the error has been changed to be handled
differently, and the member became unused.
Turns out people are bad at not combining code compiled with GCC
and Clang, and the improvement from `trivial_abi` on `unique_ptr`
is not worth the maintenance cost of having this be an opt-in
change.
Closes#2344
This avoids issues with Catch2's handler firing too early, on
structured exceptions that would be handled later. This issue
meant that the old attempts at structured exception handling
were incompatible with Windows's ASan, because it throws
continuable `C0000005` exception, which it then handles.
With the new handling, Catch2 is only notified if nothing else,
including the debugger, has handled the exception.

This should provide the same overall stdout/err, but the new
output should feel "faster" for test cases that are entered
and exited multiple times (e.g. due to generators).
This requires a bunch of different changes across the reporter
subsystem.
* We need to handle multiple reporters and their differing
preferences in `ListeningReporter`, e.g. what to do when
we mix reporters that capture and don't capture stdout.
* We need to change how the reporter is given output and
how we parse reporter's output destination from CLI.
* Approval tests need to handle multireporter option
By not materializing the lower cased tags ahead of time, we
save allocations at the cost of worsened performance when comparing
two tags.
Since there are rarely many tags, and commonly they are not
compared even if present, this is almost always a win. The new
implementation also improves the robustness of the code
responsible for handling tags in a case-insensitive manner.
A new flag, `--allow-running-no-tests` was added to override this
behaviour if exit code of 0 was desired.
This change also made `-w NoTests` obsolete, and so it has been
removed.
All of its functionality can be moved into the `MatcherBase` class,
simplifying the code a bit and removing a warning about class with
virtual member functions but no virtual destructor.
Closes#2182 as it is no longer relevant.
