    liveadder: Remove plugin, replace by compat subclass of audiomixer

    New subclass with a similar behaviour as the old liveadder, but
    a slightly different API as the latency is in nanoseconds, not
    milliseconds. Also, the new liveadder has a effective latency that
    is latency + output-buffer-duration. In practice, just setting a non-zero
    latency with the new audiomixer gives you the right behavior in 99% of the
    cases.


changed the type and unit of the "latency" property from milliseconds (guint)
to nanoseconds (guint64).

This can cause crashes in applications that use the liveadder element.

We should fix this to be really actually "compat", there's no good reason not
to do that.
