During redistribution of the data objects were created with new and
deallocated using the allocator. This works for the standard allocator
but might break with others. This fix prevents this behaviour by using
the allocator for the creation and allocation, too.
Additionally, it prevents false positive during memory leak detection
of valgrind. 

Should fix flyspray #1047!

Currently this fails due to an ambigous overload (see fs#1024).

Added a method to AMG to check whether it uses a direct solver on the
coarse level.
