stat() and friends expect a null-terminated C string. There is no way to
generate anything useful from a string that has null bytes in the
middle. It's important to catch this early, as otherwise, for example, a
QDir::exists() on such a path can return true, as the path is silently
truncated.
Extend the checks for empty file names to windows and add checks for null
bytes.

A default-constructed QDateTime is invalid, but compared equal to a
valid one referencing the start of 1970. This lead to date properties
in QML being initialized invalid but not getting an onChange if the
first value they're set to is the start of 1970.
Fixing that then lead to some tests failing. Indeed, the original
equality check involved using toMSecsSinceEpoch(), whose value is
undefined unless the datetime is valid, without a prior check on its
validity: so ensure all uses of toMSecsSinceEpoch() are guarded with
isValid() checks.
Reworked tst_QDateTime::toSecsSinceEpoch() to use its bool column
(previously unused, after separating from toTime_t(), which uses this
column for "out of time_t's range") for validity of the datetime.

Its limits() test was rather large and had some overlap with an older
qNan() test, that needed some clean-up (it combined qfloat16 values
with double and float values in ways that caused qfloat16 to be
promoted to another type, so we weren't testing qfloat16).
Renamed the qNan() test to qNaN(), separated out the parts of it that
actually tested infinity. Moved various parts of limits() to these and
rationalised the result. Split out a properties() test from limits()
for the properties of the qfloat16 type that are supplied by its
numeric_limits. Split out a data-driven finite() test to cover some
repeated code that was in limits() and extended it to test more
values. Added more tests of isNormal().

claims double has no signaling NaN. Assume the bootstrap library
doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no

The requirement to separate debug and release DLLs on Windows stems from
the Visual Studio C run-time library appearing in two different variants
(debug and release) and not mixing well. It's possible to perform builds
without optimzations and with debug symbols while linking against the
release version of the C run-time, but at the same time the debug
version of the run-time brings other developer visible advantages.
MinGW on the other hand does not have this distinction, does not ship
with separate DLLS and does also not require the VS C runtime library.
Therefore we do not need this separation for MinGW, which means that our
packages can be reduced in size and application developers wishing to
debug their applications do not have to use debug builds of the Qt
libraries or run into Qt internal debug code.

There are two cases:
In a BlockingQueuedConnection, QMetaCallEvent doesn't allocate memory
and instead passes already existing pointers through. A QSemaphore
is used to serialize data access between threads. So the constructor
taking a QSemaphore can be simplified to only accept an existing arg
array.
In a QueuedConnection, QMetaCallEvent needs to make deep copies of
the arguments, and memory needs to be allocated based on the number
of arguments. The previous code put the burden of memory allocation
on the code generating the event, while the memory was free'd by
~QMetaCallEvent. Instead, make it QMetaCallEvent's responsibility
to allocate and free the memory as needed, and adjust the code
generating QMetaCallEvents.
We can allocate the memory for types and pointers to arguments in a
single block, starting with the space for the array of void*, followed
by the space for the array of integers to avoid byte alignment issues.
By pre-allocating the space that's needed by three arguments, we can
avoid all mallocs for the majority of QMetaCallEvents.
Until this change has propagated through qt5.git, we need to keep the
old API that is still used by QtDeclarative around. Once QtDeclarative
has migrated to the new API, it can be removed.
