A variable of static storage duration that is not zero-initialized

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."

The process of loading a plugin is examplified by the qLoadPlugin
function (though not all users of QFactoryLoader use this function, they
all do something similar):
const int index = loader->indexOf(key);
if (index != -1) {
QObject *factoryObject = loader->instance(index);
if (FactoryInterface *factory = qobject_cast<FactoryInterface *>(factoryObject))
if (PluginInterface *result = factory->create(key, std::forward<Args>(args)...))
return result;
}
QFactoryLoader::indexOf already locked the mutex, but not
QFactoryLoader::instance. This commit fixes that.
Note that calling the virtual create() in the plugin's factory is not
protected by the mutex. Each plugin's factory must be thread-safe and
also create an object that works on any thread too. It's also the
responsibility of the caller of qLoadPlugin to ensure that it's called
thread-safely.

QPluginLoader hasn't unloaded in its destructor since Qt 5.0, but we

unloading, which it won't anymore.
Not unloading plugins is Qt's policy, as decided during the 5.0
development process and reaffirmed now in 5.6. This is due to static
data in plugins leaking out and remaining in use past the unloading of
the plugin, causing crashes.
This does not affect QLibrary and QLibrary::unload(). Those are meant
for non-Qt loadable modules, so unloading them may be safe.

Both e_shentsize and e_shtrndx are ELF half-words, which means C
integers of rank less than int (they're quint16). That means this
multiplcation was done actually as int, due to integer promotion from
unsigned short. So preempt the integer promotion and force them to full-
word integers (unsigned int).
While the bit-pattern result of the multiplication is the same, the
addition with e_shoff (a qelfoff_t = quintptr) wouldn't: the promotion
from 32-bit int to 64-bit would first execute a sign-extension.
Now, this shouldn't happen on regular ELF files, but it cause QLibrary

dynamic_cast and catch evaluation.
In this second and last batch, we de-inline destructors of exported

Since they are already exported, users of these classes are unaffected
