The added test case contains the binary JSON equivalent of
["ž"]
with the modification that the string's length has been set to INT_MAX. In
Value::usedStorage this length is used through the pointer d like so
s = sizeof(int) + sizeof(ushort) * qFromLittleEndian(*(int *)d);
Because 2 * INT_MAX is UINT_MAX-1, the expression as a whole evaluates to 2,
which is considered a valid storage size. However, when converting this binary
JSON into ordinary JSON we will attempt to construct a QString of length
INT_MAX.
Fixed by using String::isValid instead of Value::usedStorage. This method
already takes care to avoid the overflow problem. Additionally, I've tried in
this patch to clarify the behavior of Value::isValid a bit by writing it in a
style that is hopefully more amenable to structural induction.
Finally, the test case added in my previous patch had the wrong file extension
and is renamed in this one.

The added test case is the binary JSON equivalent of
{"a":{"š":null}}
with two modifications. First, the length of the string "š" has been corrupted
to 0xFFFFFF00. Second and more import, the Base::size field of the inner object
has been reset to 0.
On its own the first modification would normally trigger a validation error.
However, due to the second modification the Value::usedStorage for the inner
object evaluates to 0, completely disabling all further validation of the
object's contents.
Attempting to convert this binary JSON into standard JSON will lead to the JSON
writer trying to construct a QString of length 0xFFFFFF00.
Fixed by validating also objects with usedStorage == 0.

This was originally added so that you could replace a T with
QAtomicInteger<T> in the same class and still keep ABI. However, for
legacy reasons, on 32-bit x86, types larger than 4 bytes keep an old
1990s alignment of only 4 bytes, but modern std::atomic<T> for those 8-
byte types enforces an alignment of 8 bytes. Therefore, the requirement
to keep alignment is not possible to guarantee.
In other words: you may not replace T with QAtomicInteger<T> or
std::atomic<T> and assume no ABI breakages in all platforms.
This is a requirement to implement atomicity. An 8-byte type aligned to
only a 4-byte boundary could cross a 16-byte boundary or, worse, cross a
cacheline boundary. Crossing the 16-byte boundary could be bad on some
processors, but crossing the cacheline boundary (addresses ending in
0x3C, 0x7C, 0xCC and 0xFC, or 4 out of 64 possible addresses or 6.25%)
is always bad: the CPUs cannot guarantee an atomic load or store
operation.

RCC generates code that registers resources automatically on program
startup via global constructors. When linking statically and nothing
references the symbols in the .o file compiled from the RCC generated
code, then the linker will discard the embedded resources and they will
not get initialized. That is why for static linking it is necessary to
explicitly initialize resources using the Q_INIT_RESOURCE macro.
We can avoid the need for the explicit initialization in the context of
plugins that are statically linked into the application. resources.prf
can generate a .cpp file with a helper function that contains all the
Q_INIT_RESOURCE calls for all resources in the plugin. That helper
function in turn is injected into the plugin entry point, which in turn
is guaranteed to be included in the final binary.

Many subclasses of QIODevice have a functionality to block execution
until some asynchronous I/O operation completes. In case we are using
QWinEventNotifier, a typical reimplemented waitFor{ReadyRead
|BytesWritten}() function could look like:
if (WaitForSingleObject(notifier.handle(),...) == WAIT_OBJECT_0) {
notifier.setEnabled(false);
ResetEvent(notifier.handle());
bool res = GetOverlappedResult(...);
...
return true;
}
Despite the fact that the operation ends synchronously, it leaves the
notifier in a state that indicates it has received the event, so its
next call to setEnabled(true) will produce a fake notification.
So, we should reset a notifier's history before enabling it again.
