Add a way to declare _exported_ logging categories
If a library declares a logging category that needs to be used
by clients (e.g. via inline methods, macros, etc.), then the
logging category function generated by Q_DECLARE_LOGGING_CATEGORY
has to be exported.
We've seen this problem with Q_NAMESPACE, Q_GADGET, etc.: these
macros also declare functions or objects that in some cases need to
be exported.
And precisely like Q_NAMESPACE, Q_GADGET, etc., people end up
relying on the implementation details of Q_DECLARE_LOGGING_CATEGORY
(specifically, what does it expand to) in order to place the
export directives in the right place.
Introduce a more robust solution and apply it around qtbase.
Cleanup some minor code as a drive-by (remove `extern` and useless
semicolons).
[ChangeLog][QtCore][QLoggingCategory] Added the
Q_DECLARE_EXPORTED_LOGGING_CATEGORY macro, in order to allow dynamic
libraries to declare a logging category that can be then used by
client code.
