This plugin is cumbersome to support, now that MPD is migrating away
from GLib and the GLib event loop.  It has no practical advantages
over the CURL plugin.  Soup requires the bloated GType library.

Deprecated.

Fixes deprecation warnings.

This plugin has been in MPD for three years, and it has never worked.
Enough!

The hardware is obsolete, and the product does not exist anymore on
the Hauppauge web site.  Let's see if anybody complains about the
removal.

Eliminate the fallback strndup() and strnlen() implementations.
