Parameters: prepare for a generic Scale-join operation

The join()-operation allows to combine a value pulled from automation
to be combined with a local base value stored in the parameter.

When both the source and the target parameter use the same Scale,
this operation is simple; it becomes more tricky once they don't --
because then linear / logarithmic and type conversions must be handled.

I now decided to provide a generic implementation in the Scale (descriptor),
while the enclosing parameter shall handle the dispatch when connecting
to a opaque source with another Scale. And this generic implementation
relies on the same technique as was used for the parameter type conversions,
thus it should be factored out into a library header.
