Also use static initialization for QBasicAtomicInt.
A default-constructed static QBasicAtomicInt at function scope
will be dynamically initialized. It will still be zero-initialized,

When using aggregate initialization, the guard disappears.

It was unnecessary, since we only cached the static types, which are all

data races that are strictly-speaking UB, even if all the threads were
writing the same values to the same data locations.
This commit changes a little the code to simplify, since we're changing

We keep the runnables from finishing by having them block
on a QSemaphore::acquire() call inside run().
If we fail a test that precedes the call to sem.release()
further into the test, the early return will cause the
thread pool to be destroyed, which will then attempt to
wait for the runnables to finished, which, in turn wait
for the semaphore to be released.
-> dead lock
Fix by introducing a RAII object to release the semaphore
with a sufficiently large number to unblock all runnables.
That number will in some situations be too large, but that
does not matter.

The code obtained an iterator into a QHash under mutex protection,
then dropped the lock, dereferenced the iterator several times and
only retook the lock to erase the element from the QHash.
This is very smelly. QHash provides no official iterator validity
guarantees, and the container isn't const, either (which would imply
thread-safety). In particular, the dereference into the container
outside the critical section is cause for concerns.
Simplify the code, removing any doubts about its race-freedom, by
taking the payload item out of the hash before dropping the lock, and
using only the local strong reference in the remainder of the
function.
The only other references to g_pendingPermissionRequests are
insertions with unique-by-construction keys in QtAndroidPrivate's
requestPermissions(), so there was no reason to keep the item in the
hash for the whole duration of the sendRequestPermissionsResult()
call.

Add proper support for 'so' and 'bundle' suffixes. Qt wrongly assumes
.so libraries are not versioned on Apple platforms, which is
wrong. Also, the shared library .bundle which is what Apple recommends
instead of .so, are also versioned (not to be confound with the
different Core Foundation bundles, which are directory hierarchy).
For more info, see http://docstore.mik.ua/orelly/unix3/mac/ch05_03.htm.
Especially the part that reads:
"Loadable modules, called bundles in Mac OS X, have the file type
MH_BUNDLE. Most Unix-based software ports usually produce bundles with a
.so extension, for the sake of consistency across platforms. Although
Apple recommends giving bundles a .bundle extension, it isn't
mandatory."
