Details:

This patch came out of the work on bug #45088. It improves the results of all
the filtering functions of the image package and adds Matlab compatible tests
to them. 

Currently the results of stdfilt.m are not Matlab compatible, this is fixed by
this patch. The results of entropyfilt.m are currently also not Matlab
compatible, this is improved in some sense by this patch. But mostly this
patch adds new tests, that's why I put it into the patch tracker, I hope this
is fine.

The patch fixes the call to __spatial_filtering__.cc (as described in bug
#45088) in
* entropyfilt.m
* stdfilt.m


It additionally adds Matlab compatible tests to
* entropyfilt.m: tests fail. But they also fails without the fix. This is
still an improvement since we now use __spatial_filterin__.cc as it is
intended. See details in bug #45088.
* medfilt2.m: tests pass
* ordfilt2.m: tests pass
* rangefilt.m: tests pass
* stdfilt.m: tests pass

This patch is ment to be applied AFTER the patch from bug #45088 (file
#39535). Because that patch fixes the call to __spatial_filtering__.cc in
rangefilt.m.
