This can happen because QThreadData is refcounted so the managed

Currently, when one compiles a Qt plugin that is also installed
system wide to a local path added to QT_PLUGIN_PATH, you have no
way to ever load it as the global plugin will always be preferred.
This is due to the order in which the QCoreApplications::libraryPaths
are constructed, which always appended the QT_PLUGIN_PATH contents
to the end.
Now, the QT_PLUGIN_PATH contents are put first, such that the plugins
in there are preferred and loaded.
[ChangeLog][QtCore][QPluginLoader] Fixed the search order of Qt plugins
so that paths specified by the QT_PLUGIN_PATH environment variable
are searched before built-in paths.

We force a recreation of the library paths with added information on
construction of QCoreApplication. This way we can find plugins in
the application directory which only becomes known when
QCoreApplication is created. When the user changes the library path
we create a new list of the manually modified library paths and
recalculate it from the delta of original vs. modified paths when
QCoreApplication is created.
The upsides of this approach vs. keeping an explicit delta are:
* We don't need to introduce a separate data structure to hold
the added/removed status for delta items or the information that
the whole list got replaced.
* The lists never get larger than the the real library paths. An
explicit delta would have to record all modifications.
* I don't think the delta replay algorithm we would have to do
anyway could be made much more compact than the one this change
introduces.
Of course, if the user actually changes anything, the list is
duplicated. Considering that this is a rarely used function and
that we would have to save some extra information anyway, I think
we can live with this.

Long-lived threads started by Qt itself can now receive events even if
QCoreApplication hasn't been created. This is required in all threads we
start that will handle events, unless we're sure that the thread will
exit before the global application object begins destruction.
Otherwise, those threads will have race conditions dealing with the
event delivery system trying to call the QCoreApplication::notify()
virtual while the object is being destroyed.

This led to inconsistencies, the application name switching from

There was already a global static, used when setting the app name
explicitly before construction. Use it now to store the app name
in all cases (explicitly set, or fallback).

Replace the existing code in QProcess that dealt with signaling of child
processes exiting with forkfd and spawnfd. The previous code was
convoluted and hard to maintain, having shown its age in the last
year. I've been running it for a year and a half and the new
implementation is definitely an improvement.
This change replaces support for the QNX Neutrino spawn() call with the
POSIX version. We lose the ability to do setsid(), but we gain quite a
few ioctls() that were done to fill in the file descriptor mapping
structure. That's also the only OS for which we have the ability to
thread-safely chdir() before the call to spawnfd().
Another advantage is that forkfd does not require a dedicated thread
running to handle child processes exiting.

This function has a flawed design. It was flawed when it was added in
Qt 3.0.
A "false" return value is racy: any other thread running may post events
to the current thread, thus making the result stale. That includes Qt
starts for its own purposes when it comes to the main thread, like the
Scene Graph thread, the QProcessManager thread, the Windows
QAdoptedThread watcher thread, the Windows pipe writer thread, etc.
A "true" return is stable only if the selected thread is stopped, which
includes selecting the current thread (the case of QCoreApplication).
For that reason, this method should not be public, but a protected one
so that a public static could call it. But even that would not solve the
race condition from the previous paragraph (hence why
QCoreApplication::hasPendingEvents being deprecated too).
And, to top all of that off, all but one of the implementations access
the GUI thread's event loop counter in a non-thread-safe manner. I've
changed the documentation to restrict to the only currently-working use-
application.
