#4957 closed defect (fixed)

dlopen() needs a dlclose() for the dynlib handle to be given up

Description

In filtermanager.cpp there is a call to dlopen(). There is no corresponding call to dlclose(). The dynlib will be ref count incremented on the dlopen(). So the handle will never be reclaimed unless the count is decremented by the dlclose().

Closing the dynlib handle does not mean the symbol is closed too. Only that the ref count on the dynlib is decremented. When the symbol is closed the handle will eventually have a ref count of zero and the handle will be reclaimed.

(In [17232]) Fixes #4957. This removes most of the Qt3 stuff from the filter manager, adds some error reporting and makes sure external filter libraries are closed when we are done with them.
