tests/thirdparty/doctest/doctest.h is doctest 2.4.12, imported in #4771. Two weeks later, #4801 hand-edited translateActiveException() to declare "String res;" inside the translator loop instead of before it, so a translator that does not match does not leave a previous translator's result in "res" for the next iteration to see. Nothing recorded this, so re-vendoring doctest.h from upstream would silently drop the fix. Add a comment at the patched site naming the version, the PR and the reason, so a future re-vendor knows to re-apply it. Also fix two stale comments in doctest_compatibility.h: - The DOCTEST_THREAD_LOCAL comment referenced Xcode 6/7, which is no longer supported; reword it to explain why the define must stay regardless (it keeps doctest's own thread_local usage out of the way of the same Clang/MinGW crash that JSON_NO_THREAD_LOCAL works around in the library, see ci_test_no_thread_local). - The <iosfwd> include's comment justified it with tests that define "private" as "public"; no test under tests/src does that any more (removed by #2352). Reword the comment instead of dropping the include, since confirming it is safe to drop needs the full CI matrix including MSVC 2015+. Verified locally that tests/src/unit-readme.cpp still builds and passes 17/17 with these headers. Closes #5714 item 9. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
