increase the compile-time size to 32k, to match what our Catch2

The relevant MS system calls (say they) don't support date formatting
for years < 1601 (but apparently do in fact) and the year field of the
data structure is unsigned, so can't support years < 0. As a result,
the windows back-end for QSystemLocale failed for negative years.
So replace year < 1601 with a place-holder and substitute after
formatting.
Added new tests (based loosely on one in qtdeclarative that failed) to
verify that this actually works. These reveal that macOS also fails to
handle negative years; marked as expected failure there pending a fix.

Provide basic boiler plate that sets up the baseline (aka lancelot)
framework specifically for comparing the appearance of widgets, and
implement test functions for QSlider and QPushButton.
Widgets should always look the same if the QPA platform, the OS
version, and certain UI-impacting attributes are identical. Ie.
on any macOS 10.15 machine that runs in "Light" mode, widgets
look the same. On a macOS 11 machine, they might look different.
On an OpenSUSE machine using the fusion style things might look
different from a Ubuntu machine.
The helper function removes DPR differences - images are always
scaled to a DPR of 1.0, which allows us to compare the image\
content and not get distracted by them having different dimensions
(and the fuzzy comparison of images might make the system tolerate
scaling artefacts).
Note: For now, this test is meant to be run locally, either when
testing changes to style code, or when checking how QWidget based
UIs would look on newer version of an operating system. In CI the
test is run, but then skipped in CI as the baseline server is
not configured.

Fix by making the variable atomic. Interestingly enough, relaxed

happens in read- and write-side critical sections, and if
qt_file_engine_handlers_in_use is wrong w.r.t. to the actual list, the

Quite some code in Qt takes a copy of a QRegularExpression and then
changes something on it (e.g. the case sensitivity) based on some
other criteria:
QRegularExpression copy = orig;
if (cond)
copy.setPatternOptions(copy.patternOptions() | CaseInsensitive);
use(copy);
This pattern can be found in QAIM, QString-related classes, and so on.
The "problem" is that if the attempted modification is a no-op, we'd
still invalidate the copy object (by detaching). Even if no detaches
are involved, setting the same pattern or options on a QRE object
shouldn't require a relatively expensive pattern recompile.
In summary: don't detach/mark a QRE object as dirty if a setter didn't
actually do a modification.
