patch series

Patch 1/2 fixes the ordering_map bounds problem and sets channel-mask = 0 when
there are more than 64 channels.

Is that the kind of thing you meant Slomo?

Patch 2/2 addresses the hypothetical situation where the ordering map is not
filled out because self->channel_positions == NULL or some other reason, which
is indicated externally in gst_interleave_set_channel_positions by setting the
channel_mask to 0 but forgotten internally when gst_interleave_collected comes
to use the uninitialised array (I am not certain that this situation is
actually possible).
