1c6bf3e09e Port from container::count() and length() to size() - V5
This is a semantic patch using ClangTidyTransformator as in
qtbase/df9d882d41b741fef7c5beeddb0abe9d904443d8, but extended to
handle typedefs and accesses through pointers, too:

    const std::string o = "object";

    auto hasTypeIgnoringPointer = [](auto type) { return anyOf(hasType(type), hasType(pointsTo(type))); };

    auto derivedFromAnyOfClasses = [&](ArrayRef<StringRef> classes) {
        auto exprOfDeclaredType = [&](auto decl) {
            return expr(hasTypeIgnoringPointer(hasUnqualifiedDesugaredType(recordType(hasDeclaration(decl))))).bind(o);
        };
        return exprOfDeclaredType(cxxRecordDecl(isSameOrDerivedFrom(hasAnyName(classes))));
    };

    auto renameMethod = [&] (ArrayRef<StringRef> classes,
                            StringRef from, StringRef to) {
        return makeRule(cxxMemberCallExpr(on(derivedFromAnyOfClasses(classes)),
                            callee(cxxMethodDecl(hasName(from), parameterCountIs(0)))),
                        changeTo(cat(access(o, cat(to)), "()")),
                        cat("use '", to, "' instead of '", from, "'"));
    };

    renameMethod(<classes>, "count", "size");
    renameMethod(<classes>, "length", "size");

except that the on() matcher has been replaced by one that doesn't
ignoreParens().

a.k.a qt-port-to-std-compatible-api V5 with config Scope: 'Container'.

Added two NOLINTNEXTLINEs in tst_qbitarray and tst_qcontiguouscache,
to avoid porting calls that explicitly test count().

c849c48d19 Autotest/Unix: request zero-sized core dumps for crashing code
Unix systems have got crash loggers in the past 15-20 years, notably
macOS and Linux (abrtd, systemd-coredumpd, etc.). By setting the core
dump limit to zero, those tools should be mostly inhibited from running
and thus not interfere with the parent process' timeouts. Even for
systems without core dump loggers, disabling the writing of a core dump
to the filesystem should also help.

aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

supposed to test the address reusability, so a clean close on a server
that never accepted a connection should not cause reusability issues.

782fbe0f63 The new signal pendingConnectionAvailable is added to QTcpServer
The new signal pendingConnnectionAvailable is emitted after a new
connection has been added to the pending connections queue. Connect
to this signal and call nextPendingConnection to handle incoming
connections.

The existing unchanged newConnection signal is emitted after the
overridable function incomingConnection is called, regardless of whether
a new connection is added to the pending connections queue in the
incomingConnection function or not.

If a subclass that overrides incomingConnection either decides to not
add all incoming connections to the pending connections queue, or to
postpone adding the connection until a handshake is successfully
completed, the pendingConnectionAvailable signal should be to used,
because this signal directly corresponds to insertions to the pending
connections queue.

479c95729a Support global data tags in blacklisting identification of test-cases
Previously the blacklisting file format only worked with slot:data or
plain slot names for the items to blacklist. However, tests with
global data report themselves with the global data-row tag in the same
way as function-specific ones do; and tests which have both join the
two as slot(global:data) in the test output name, so the reader is apt
to mistake global:data for a data tag. In any case, it is potentially
desirable to be able to blacklist a function with either or both of
global and local data-row tags specified. Add support for that and
remove a blacklisting that was only needed due to the lack of this
support.

For now, make the new parameter to checkBlackLists() optional, so
that qtdeclarative's qmltest framework can adapt to this change.

4e695eece7 QWindowsPipeWriter: do not clear the buffer in thread pool callback
In a blocking application, receiving the results of write operations
must be synchronized with the waitFor...() functions. But, clearing
the buffer in another thread can cause the code

  localsocket.write(...);
  QVERIFY(localsocket.bytesToWrite() > 0);

to fail unexpectedly, if the socket has been disconnected between
the calls.

So, defer resetting the buffer until checkForWrite() is called.

c7e0a1a966 Fix flaky test timing out sometimes while waiting for data
The test used to hang on waitForRead(), sometimes, which underneath
involve a poll()+read() syscall pair.
When this happened, the IMAP data came together with the proxy data on a
previous poll()+read() call and the proxy code had already consumed it.

We now wait for data only if data is not already available.

5d68858ba7 QLocalSocket/Win: fix waitFor...() functions for write-only socket
There were several issues with the socket state checking when the pipe
reader is not running:

  - the number of object handles in the WaitForMultipleObjectsEx()
    call might have been zero;
  - a call to the waitForDisconnected(-1) might have hung;
  - we did not perform a loop iteration for the waitFor...(0) calls,
    so disconnect detection was unreliable.

These issues are related to the same code, so they don't seem to be
addressable separately.

6481733d45 QLocalSocket/Win: do not flush the pipe in disconnectFromServer()
In the case where we have pending data to write, calling flush() here
may cause the device to close immediately, if the pipe writer already
got a result of the last operation from the thread pool. In this
scenario, the device does not enter the 'Closing' state, which leads
the following code to unexpectedly fail on Windows

  socket.write(...);
  socket.disconnectFromServer();
  QVERIFY(socket.waitForDisconnected());

Removing the call to flush() makes the behavior consistent with the
implementation on Unix.

d9c0af92bd QLocalSocket/Unix: fix aborting the socket
According to the documentation, calling abort() should immediately
reset the socket to its initial state. This includes:

  - closing the file descriptor;
  - closing the QLocalSocket as an I/O device;
  - canceling a pending outgoing connection, if it exist;
  - reseting 'serverName' string.

So, adding a call to close() resets the state entirely.

e095fa7f9c Allow to set TCP network listen(2) backlog
Qt has a hardcoded backlog value of 50,
this allows for applications to tune this
value. Modern kernels have the SYN cookie
feature that reduces pressure from an
flood attack, the backlog setting however
is then a queue for most likely real
completed (SYN/ACK) connections hence, it's
easy to get clients connections dropped
with this very small limit.

[ChangeLog][QtNetwork][QTcpServer] Added
QTcpServer::setListenBacklog() to be able
to have control over the listen backlog feature.
