In C++20, QDateTime is a direct equivalent of a sys_time<milliseconds>
time point. (Before, it might not have been, because system_clock before
C++20 was not guaranteed to be tracking Unix time, AKA UTC time without
leap seconds.) To be specific, sys_time<milliseconds> corresponds to
a QDateTime using the Qt::UTC timespec.
This patch:
1) adds named constructors taking time_points:
* a generic one taking any time_point convertible (via clock_cast) to
a system_clock (this obviously includes system_clock, but also e.g.
utc_clock)
* another couple taking local_time, interpreted as a duration from
1/1/1970 in local time.
2) adds a named constructor from zoned_time (i.e. a sys_time + a
timezone), that we can easily support via QTimeZone.
3) add conversion functions towards sys_time, matching the existing
to(M)SecsSinceEpoch() functions.
[ChangeLog][QtCore][QDateTime] QDateTime can now be constructed
from std::chrono::time_point objects (including local_time), as
well as from std::chrono::zoned_time objects. Moreover, they
can be converted to std::chrono::time_point using system_clock
as their clock.

std::chrono::year_month_day and related classes offer very
convenient to specify dates.
This patch adds implicit constructors to QDate to support this
convenience, e.g.:
// YYYY-MM-DD, DD-MM-YYYY, MM-DD-YYYY formats:
QDate d1 = 1985y / December / 8;
QDate d2 = 8d / December / 1985;
QDate d3 = December / 8d / 1985;
// Indexed weekday:
QDate d4 = 2000y / January / Monday[0];
QDate d5 = 2000y / January / Monday[last];
and so on.
These are all implemented using the conversion from the std
calendaring classes to sys_days. Conversions between sys_days
and QDate are also added, since they're basically "for free".
I don't expect "ordinary" users to stumble upon it, but it's
worthy mentioning that std::chrono::year *does* have a year
zero (hence, year_month_day in year 0 or below are offset
by one with the corresponding QDate). I've left a note
in the documentation.
[ChangeLog][QtCore][QDate] QDate (and therefore QDateTime)
is now constructible using the year/month/day/week classes
available in the std::chrono library. Moreover, it now
features conversions from and to std::chrono::sys_days.

QAbstractProxyModel::headerData tries to do the "smart" thing and
map sections in the proxy to sections in the source. However there's
no "mapSectionToSource" virtual. Instead, to map horizontal headers, the
code builds a proxy index at row 0 and section N, maps it to the source,
and finds out which source column it gets mapped to. (Same story
for the vertical headers).
... in general this can obviously fail, say you've got a "horizontal
scrambling" proxy model, but in the common case this is OK.
Except, if the proxy is empty (e.g. 0 rows or columns). In this case,
it asks for an illegal index, and if you reimplemented index() yourself
(which you must, since it's a pure virtual in QAPM) and you do bounds
checking, you'll not be pleased at the result.
This turns out to be a massive API liability. To fix this somehow properly,
we can decide that empty models don't get the section remapped (easy).
Less easy is the fact that, when the model does get some data, we have to
emit headerDataChanged() otherwise the views will get broken. So add
this logic too.
Note that QAPM does not normally forward any source model's signal -- a
subclass has to connect to them and handle them explicitly. That's
*another* API liability, all over the place -- data(), headerData(),
flags(), etc.
What I mean by this is that one can create a valid QAPM (by implementing
its pure virtuals) that however is immediately broken by the convenience
that QAPM provides for the rest (data(), headerData(), etc.).
This commit doesn't try and change this in any way, but I'm less and
less convinced of the usefulness of QAPM in its current shape.

Whenever a source file is touched that belongs to the bootstrap library,
all bootstrap tools are rebuilt. This includes moc. The moc binary
however, is a dependency whose invalidation results in a rebuilt of
quite some parts of Qt.
There's no easy way to turn off this dependency. To mitigate the
rebuilds, the bootstrap lib now can use a copy of the corelib sources.
That means the bootstrap lib is not rebuilt if its sources are changed.
This is basically the situation we had in Qt5.
The sources are not updated on reconfiguration. There's a new target
'update_bootstrap_sources' that can be built to update the copied source
tree of the bootstrap lib.
This new behavior can be controlled with the variable
QT_USE_BOOTSTRAP_SOURCE_COPY. It's on by default for developer builds.

The example was refactored to use the PMF connection syntax.
However this introduced a problem: when connecting a QAbstractButton
to a slot that has a default parameter, the semantics of the connection
change between string-based connections and PMF.
Specifically: when connecting the
QAbstractButton::clicked(bool checked = false)
signal to a slot like
View::zoomIn(int level = 1)
then a string-based connection like
connect(button, SIGNAL(clicked()), this, SLOT(zoomIn()))
would call zoomIn without carrying the signal's parameter over.
In other words, zoomIn's parameter is defaulted. The same connection
using PFM instead is
connect(button, &QAbstractButton::clicked,
this, &View::zoomIn)
which would "connect" the arguments. This makes emissions that pass
false as clicked's parameter result in a zoomIn by 0.
Fix it by avoiding the default parameter of zoomIn -- just split
the function in two (zoomIn and zoomInBy).

MSVC will export any function in an exported class, including inline
ones. Conversely: client code calling inline functions in imported
classes will end up simply calling the symbol of the function, even if
the function is fully inline.
This is a problem for adding post-C++17 APIs in Qt. Such APIs are added
as inline functions protected by feature-macro tests, so that both Qt
and client apps can use any C++ version they want (any combination
works).
However, if we add a function using post-C++17 API to an exported class,
then the combination "Qt built in C++17" + "client built in post-C++17"
won't work any more. The client will expect the symbol for that function
to be exported by Qt, but Qt won't have it (built in C++17).
As a workaround, add a marker that turns these functions into "faux
templates", like Q_WEAK_OVERLOAD does.
