Its "rules" are actually guidelines, its suggested regex was wrong,
its actual implementation was fuzzier than its documentation suggested
and the exception it tacitly permitted should be distinguished from

Explain why the situation is tricky, fix the regex mentioned (making
it more readable, too) and note what might be worth doing a little

This might be useful for IDE or other tools to be made aware of Qt macros.
This is inspired to what QtCreator[1] and moc-ng[2] does. But they are forced
to redefine or inject code at precise location which might be difficult.
This is going to make it easier to use libclang in qdoc.
With this change, the tooling can just predefine the macro QT_ANNOTATE_FUNCTION
and QT_ANNOTATE_CLASS to get what they need.
Example with libclang:
"-DQT_ANNOTATE_CLASS(type,...)=static_assert(sizeof(#__VA_ARGS__),#type);"
"-DQT_ANNOTATE_CLASS2(type,a1,a2)=static_assert(sizeof(#a1,#a2),#type);"
"-DQT_ANNOTATE_FUNCTION(a)=__attribute__((annotate(#a)))"
"-DQT_ANNOTATE_ACCESS_SPECIFIER(a)=__attribute__((annotate(#a)))"
"-DQ_CLASSINFO(name,value)=static_assert(sizeof(name,value),\"qt_classinfo\");"
"-DQ_REVISION(v)=__attribute__((annotate(\"qt_revision:\" QT_STRINGIFY2(v))))"

The logic for activating a delayed popup menu on QToolButton is a bit
cumbersome: when the button is pressed, a timer is started. This timer
however doesn't get reset if the button is released before the timer
expires. Instead, the function triggered by the timer checks if the
button is pressed at that time. If so, the popup menu is shown.
This logic allows the user to press-release a QToolButton many times
and suddenly get a popup menu appear way before the expected timeout
for the popup expired. That's because the first press started the timer,
and then the button happened to be down when the timer expired.
Instead, always *re*start the timer on a button press, and cancel
the timer when the button is released.

- QTextBrowser backend seems to assume a DPI of 96 for all

However, on OS X this resulted in font sizes too small to read.

Fix by casting the lhs of the left-shift operator to uint

result as the old code, but without UBs.
It is critically important that the result is identical
to the old code (modulo the compiler exploiting the UB,
which this patch aims to prevent even in future compilers),
because the function is inline, and changing the hash value
would mean changing the layout of a QHash<QModelIndex,.>
