QSqlQuery is a broken value class. Copying one object would mean
copying database state (the result set, the cursor position, etc.)
which isn't generally available for all database drivers.
For that reason, the current implementation does not honor value
semantics -- modifying a QSqlQuery object has visible side effects
on its existing copies (!).
The correct solution is to accept that QSqlQuery is a move only
type, not a value type. Add move semantics to it, and deprecate
its copies.
(We can't just *remove* copies in Qt 6 due to SC/BC constraints).
[ChangeLog][QtSql][QSqlQuery] QSqlQuery copy operations have
been deprecated. QSqlQuery copy semantics cannot be implemented
correctly, as it's not generally possible to copy a result set
of a query when copying the corresponding QSqlQuery object. This
resulted in modifications on a QSqlQuery having visible (and
unintended) side effects on its copies. Instead, treat QSqlQuery
as a move-only type.

The hashing seed's type has been changed from int to size_t in Qt 6.
However the functions setting/getting the seed, and the seed itself,

In particular that influences BundledLibrary targets.
Most internal targets already depended transitively on Qt::Platform
via Qt::Core as a public dependency. This was not the case for
BundledLibrary targets which don't link to Qt::Core.
This led to compilation issues in user projects when targeting
WebAssembly, due to mismatched flags between a bundled Harfbuzz vs
a user project. Probably other subtle issues as well (e.g. none of the
Windows specific compile definitions were passed to bundled libs).
Bundled libraries depend on PlatformCommonInternal already, so make
PlatformCommonInternal turn depend on the public Platform target.
I thought that was already the case, but we merely relied on the
Qt::Core dependency.
Note that Qt::Core should still list Platform as a public dependency,
so it gets propagated to user projects.

Because this is misleading:
socket.bind(QHostAddress::AnyIPv4);
The conversion of enum to int has preference over the construction of
QHostAddress from enum, so that ends up calling bind(6), which attempts
to bind to privileged port 6 and just returns with error. Meanwhile,
socket.bind(QHostAddress::AnyIPv4, 0);
does construct the QHostAddress because that is preferred to converting
the int to the BindMode enum.
Ideally we'd simply add the overload to QAbstractSocket but we can't do
that because QHostAddress depends on QAbstractSocket. So I've added a
Qt7 task to invert that dependency.

Test we get the same starts of various days. Some coming changes shall
break some of these, but they should all be back to working by the
time we're taking account of DST before 1970 as well as after.
The first two or three test-cases work by accident in most zones, at
present, due to the zone-based code-path ignoring the LMT period
before the zone's first transition; but Europe/Helsinki had a renaming
transition in 1878, so does see its pre-zone offset between then and
the switch to UTC+2 in 1921, leading to failures in exactly the zone
Coin tests. So suppress these three test-cases pending later fixes.
On Windows, the next text (still pre-epoch) gets bogus zone data for
its LocalTime, so suppress that likewise.
