QLibrary: introduce a mutex to protect non-atomic internals
And make pHnd atomic.
The majority of the variables is updated in QLibraryPrivate::load_sys
and updatePluginState(), which get the mutex protection.
QLibraryPrivate::unload_sys() doesn't need a mutex protection because we
have the refcounting.
[ChangeLog][QtCore][QLibrary & QPluginLoader] Fixed a number of race
conditions caused by having two QLibrary objects pointing to the same
library being operated in different threads.
Fixes: QTBUG-39642
Change-Id: I46bf1f65e8db46afbde5fffd15e1a5b3f5e74ea4
