Too many open DB connections

[Maik Qualmann]

Hi,

we have a problem with some database operations (MySQL) with too many open 
connections established. For example, recognize faces. Because QThreadStorage 
deletes the thread data when the thread is exit and thus also closes the DB, 
the DB is opened again at the next DB action. To test the patch extensively, I 
think only to commit for digiKam 5.9.0.
