[RFC PATCH v2 REBASE 03/18] conf: Introduce new address type mdev

[Erik Skultety <eskultet@xxxxxxxxxx>]

Since the address element is much easier extendible by attributes adding
more and more elements, starting with <uuid>, to the <source> element
once we find out we need more data to identify a mediated device. By
introducing a new address type rather than using plain elements, we also
remain consistent with all other devices that can make use of the
address element.
