Amends b03385f9cf.
Java-style iterators are scheduled to be deprecated.
The general pattern used in the patch is that instead of copying an
input list, then iterating over the copy with some calls to
it.remove() (which leads to quadratic-complexity loops), we simply
copy conditionally (a la remove_copy_if instead of remove_if).
To make clearer what's going on, rename the outgoing list to
'unhandled'.
To avoid having to touch too much of the loops' structure, which
sometimes is quite convoluted, use qScopeGuard to do the append to
'unhandled', unless the original code removed the element.

The array of QAtomicPointer<QMutex> can be initialized using relaxed
stores of nullptr, since nullptr is the whole data. But once we store
an actual QMutex pointer in the array, we need to publish the indirect
data thus created. We did this, with testAndSetRelease(); what was
missing was a corresponding acquire fence on load, without which there
is no happens-before relationship between the writes performed by the
QMutex ctor and the reads performed by a subsequent mutex.lock(), say,
on the same data.
Fix by adding acquire fences to all loads. That includes the dtor,
since mutexes may have been created in different threads, and never
been imported into this_thread before the dtor is running.
As a drive-by, return a new'ed QMutex that was successfully installed
directly to the caller, without again going through a load-acquire.

A recurring problem with the Q_NAMESPACE macro is that it declares
an object (staticMetaObject) in the surrounding namespace. That
object lacks any export/import qualification to make it usable
with shared libraries.
Introduce therefore another macro to work around this issue, allowing
the user to prefix the object with an exporting macro, f.i. like this:
Q_NAMESPACE_EXPORT(Q_CORE_EXPORT)
The old macro can simply then be rewritten in terms of this new one,
supplying an empty export macro.
Note that NOT passing an argument to a macro expecting one is well
defined behavior in C99 -- the macro will expand an empty token.
Of course, MSVC doesn't like this and emits warnings. As a
workaround, use a variadic macro.
[ChangeLog][QtCore] Added the new Q_NAMESPACE_EXPORT macro. It
can be used just like Q_NAMESPACE to add meta-object information
to a namespace; however it also supports exporting of such
information from shared libraries.
[ChangeLog][Potentially Source-Incompatible Changes] Prefixing
Q_NAMESPACE with an export macro may no longer work. Use the new
Q_NAMESPACE_EXPORT macro for that use case.

A function may almost always have static storage duration, but that
does not necessarily mean that we can store and load pointers to them
without memory ordering. Play it safe and use store-release and
load-acquire for them (which combines to ordered for the fetchAndSet
call in qInstall*Handler(), as we don't know what the caller will do
with the returned function pointer).
Also change the initial value of the atomic pointer to nullptr.
Nullptr already signified the default handler in qInstall*Handler(),
so the API doesn't change. But by using nullptr to mean default, we
place these variables in the BSS segment instead of TEXT, save dynamic
init, or at least a relocation, and we dodge the smelly comparison of
function pointers, using comparison against nullptr instead.
Also, as a drive-by, put the call to ungrapMessageHandler() in a
scope-guard. Both the message handler, as well as the Qt code calling
it (toLocal8Bit()!), may throw, and that would stop all further
logging.
The code still has one problem: When a logging action is underway, and
another thread exchanges the message handler, we might still execute
code in the old handler. This is probably not a problem in practice,
since no-one will use a dynamically-compiled function for logging
(right? :), but should probably be documented or fixed. This patch
does not address this issue, though.
