Thanks for reviewing Stefan... committed it to CVS some seconds ago.

For the code duplication aka copy&paste design I'll think about some kind of
base class for all audio filters once I make the next one.

        * gst/audiofx/audiofx.c: (plugin_init):
        Add new element "audioamplify". This allows scaling of raw audio
        samples, similar to the "volume" element, but provides different modes
        for clipping and allows unlimited amplification. It's mainly targeted
        for creative sound design and not as a replacement of the "volume"
        element. Fixes #397162
