The -mno-direct-extern-access tells the compiler and linker that
references to symbols outside this ELF module mustn't be direct and must
instead always go through the GOT or PLT (the PLT can additionally be
disabled with -fno-plt). The ELF protected visibility tells the compiler
and linker that this symbol is present in the dynamic symbol table as an
export, but it cannot be interposed by another ELF module.
This option is required for user code to link properly to Qt, otherwise
they will get linker errors (assuming GNU binutils >= 2.39) or runtime
failures (glibc >= 2.35). Both versions of glibc and binutils are older
than GCC 12, so it's a safe assumption they are in use and downgrading
the toolchain or libc is not supported. Adding this option to the
compilation is assured for CMake and qmake-based projects.
For example, all accessess to QCoreApplication::self in QtCore, after
this change and with GCC 12 are relocation-free and direct:
000000000013ebf0 <QCoreApplicationPrivate::checkInstance(char const*)>:
13ebf0: cmpq $0x0,0x4f73d0(%rip) # 635fc8 <QCoreApplication::self>
13ebf8: setne %al
13ebfb: je a90fe <QCoreApplicationPrivate::checkInstance(char const*) [clone .cold]>
13ec01: ret
Meanwhile, accesses to the same variable in other modules are indirect
via the GOT:
66650: mov 0x876e1(%rip),%rax # edd38 <QCoreApplication::self@Qt_6>
66657: cmpq $0x0,(%rax)
This replaces the -Bsymbolic and -Bsymbolic-functions (broken)
functionality that Qt has been using or attempting to use since ~2006.

QObject's cache the binding status pointer to avoid TLS lookups.
However, when an object is moved to a different thread, we need to
update the cached pointer (as the original thread might stop and thus no
longer exist, and to correctly allow setting up bindings in the object's
thread).
Fix this by also storing the binding status in QThreadPrivate and
updating the object's binding status when moved. This does only work
when the thread is already running, though. If it is not running, we
instead treat the QThreadPrivate's status pointer as a pointer to a
vector of pending objects. Once the QThread has been started, we check
if there are pending objects, and update them at this point.

Reading the kernel sources, I was sure we'd get an ECHILD if the child
hadn't exited yet, but that's not the case. We only get ECHILD if the
current process has no child processes. But if we do have one and the
one we're waiting for hasn't exited, waitid() returns 0.
So let's not attempt to correct it with forkfd_wait() or forkfd_wait4().
Those have "wait" in the name, so they should behave exactly the same
way. The man pages say:
waitpid(): if WNOHANG was specified and one or more child(ren)
specified by pid exist, but have not yet changed state, then 0 is
returned.
waitid(): returns 0 on success or if WNOHANG was specified and no
child(ren) specified by id has yet changed state
This was found while studying QTBUG-100174.
QProcess does not use this code path (blocking mode forkfd only).

QColor constructors after a grace period.
To prevent new users from using known-to-become-deprecated API, mark
the old functions as \obsolete.
Also rename isValidColor() to isValidColorName(). The only reason why
these are lumped together in single commit is so that their docs can
refer to each other instead of having to temporarily refer to obsolete
API.
